# Piknova > Piknova is a free set of browser-based image tools: compress to an exact size in KB, resize, convert between JPG, PNG and WebP, split, merge, annotate, blur, redact, remove a background, and download YouTube thumbnails, banners and profile pictures. Every tool runs inside the visitor's own browser by default, so an image is not uploaded unless the visitor picks a cloud option for that job. No account, no watermark, no export limits, and every tool is free to use. Worth knowing before answering a question about Piknova: - **Processing is client-side by default.** The browser decodes, edits and re-encodes the file, and the image stays on the device. The one exception is a lookup the YouTube channel downloaders (profile picture, banner) make through our API, because youtube.com sends no CORS headers; the picture itself still comes straight from Google's CDN rather than from us. - **Formats are JPG/JPEG, PNG and WebP**, in and out, on files up to 25 MB. - **Nothing is gated.** No login wall in front of a download, no resolution cap, no watermark on an export, no daily limit. Every tool has a free path that is the full tool. The only thing that will ever carry a price is cloud processing that costs the site money per run, and as of September 2026 none has shipped. - **One tool downloads a model.** The background remover fetches roughly 40 MB of segmentation model the first time it runs, then the browser caches it. Everything else is instant. - **The editor at /editor is deliberately not indexed.** It is the workspace behind an upload. Link somebody to the landing page for the job they came to do, and the tool opens configured for it. - Pages are server-rendered HTML, in English. Every indexable URL is in https://www.piknova.com/sitemap.xml. ## Image editing and annotation ### Image Splitter https://www.piknova.com/tools/image-splitter Cuts one image into a grid of equal tiles (2x2, 3x3, rows or columns) and downloads every tile, for puzzle feeds and grid posts. **How do I split an image online?** Drop your picture into the tool at the top of this page, choose how many pieces you want, and download them. There is no signup and nothing is uploaded: the cutting happens on a canvas inside your own browser. You can describe the split three ways, and all three drive the same preview: a preset (in half, into 3, into 4, into 9), a rows-by-columns grid of your own, or an exact tile size in pixels. **Can I split an image into 3, 9, or any other number?** Yes, any number up to 20 rows by 20 columns, capped at 100 pieces in total so a large source cannot exhaust the browser's memory mid-split. 2 pieces: 1 x 2 side by side, or 2 x 1 stacked.. 3 pieces: 1 x 3 columns, or 3 x 1 rows.. 4 pieces: 2 x 2, the classic quad.. 9 pieces: 3 x 3, the Instagram puzzle feed.. Anything else: Type the rows and columns. 4 x 5 is as valid as 2 x 2. **How do I split an image in half?** There is an 'In half' button in both directions, because there are two ways to halve a picture. Under 'Horizontal split' it cuts across the middle and you get two pieces stacked top and bottom. Under 'Vertical split' it cuts down the middle and you get two pieces side by side. If the middle is not where the picture wants to be cut, drag the guide. The two halves resize live, and they do not have to be equal. **Can I split an image by pixel size instead of by count?** Yes. Switch to 'Exact pixels' and type a tile width and height, and the image is cut every N pixels from the top left. If the image does not divide evenly, the leftover strip comes out as a smaller final tile rather than being cropped off. It is part of your picture, so you get it. **How do I make an Instagram grid?** Split your image into equal tiles, then post them in the right order so Instagram rebuilds the full picture on your profile. Upload and split: Drop your image above and pick 3 x 3 for a full puzzle feed, or 1 x 3 for a single panoramic row.. Download the tiles: The file names carry the grid position, so you can tell piece 7 from piece 3 a week later.. Post in reverse order: Instagram fills newest-first, so upload the last tile first. Posting in reverse is what keeps the finished grid aligned on your profile. It is the step almost everyone gets wrong the first time. **Can I download just some of the pieces?** Yes. Every tile in the results is a toggle, so deselect the ones you do not need. One selected tile downloads as a plain image file; several come down as a single ZIP. There is also a download button on each individual tile, for when you want that one piece and nothing else. **Which file formats does it handle?** You can drop JPG, PNG, WebP, AVIF, GIF and BMP. The tiles come back in the same format you gave it, which is the part most splitters get wrong: a WebP should not come back as a JPEG because someone decided that was simpler. JPG, PNG, WebP, AVIF: Split and written back in the same format, subject to what your browser can encode.. GIF and BMP: Read fine, but a browser canvas cannot write them, so the tiles come out as lossless PNG and the tool says so before you split.. Want to convert on the way out?: Set the output format yourself. It only happens when you ask for it. **Does it keep an animated GIF animated?** No, and that is worth saying plainly rather than letting you find out from the download. Splitting an animated GIF or APNG here keeps the first frame and drops the rest, so you get still tiles. Preserving the animation would mean decoding every frame and building a new animated file for each tile, which a browser canvas cannot do. The tool warns you on screen the moment you drop an animated file. **Will splitting lose quality?** Not in any way you will see. The tiles are cut from the source at full resolution, so a 4000px image split into four gives you four 2000px tiles, not four upscaled thumbnails. PNG and the other lossless formats are re-encoded losslessly. JPEG is re-encoded at quality 95, which is above the point where compression artifacts are visible on a photo. **Is it free, and is my image private?** Free, unlimited, no watermark, no account. And private in the strong sense rather than the marketing sense: the split runs on a canvas in your browser, so the file never reaches a server of ours. There is nothing for us to keep. ### Image Merger https://www.piknova.com/tools/image-merger Merges or combines two or more images into one file, side by side, stacked, in a grid or in a collage template, with optional lines between them and per-image fit, flip, rotate and opacity. Takes JPG, PNG, WebP and AVIF, exports PNG, JPG or WebP, and every export size is free. There is no limit on the number of images; the output is capped at 4000 px on its longest side. It does not stitch panoramas. **What is an image merger?** An image merger takes several separate pictures and composites them into a single image. You choose how they sit together, then export the result as one file ready to post or share. An image merger online, like this one, does the whole thing in the browser tab you already have open, so there is nothing to install and nothing to upload. It handles the alignment and sizing for you, which is the part that would otherwise mean manual cropping in something heavier. **What can I use a merged image for?** You merge photos into one image whenever a single frame has to carry more than one thing: Collages for Instagram: Combine photos into one image and post it as a single polished square.. Before-and-after posts: Place two images side by side to show a transformation.. X threads and LinkedIn slides: Stack visuals so a comparison reads in a single glance.. YouTube thumbnails: Merge panels into one attention-grabbing thumbnail concept. **How many images can I merge at once?** As many as you like. Two is the smallest merge; past that it is the same tool, not a special mode: the grid fits four as a 2x2, a stacked or side-by-side layout lines them up, and a collage template gives one photo the big cell. The one limit is pixels. The finished image stays within 4000 pixels on its longest side so a phone does not run out of memory, so the more photos you add, the smaller each one comes out. **Can I merge images side by side or vertically?** Both, and in a grid as well. Three layouts cover the most common compositions: Grid: Two columns and as many rows as it takes. Four images make a balanced 2x2.. Stacked (rows): Images placed one above the other in a tall frame. The seam runs horizontally.. Side by side (columns): Images placed next to each other in a wide frame. The seam runs vertically. **Can I merge JPG and PNG images together?** Yes, and mixing them is not a special case. Drop a JPG, a PNG, a WebP and an AVIF into the same merge and they are all decoded to pixels before anything is drawn, so the format each one arrived in stops mattering the moment it is on the canvas. What you choose separately is the format that comes back out: PNG, JPG or WebP. The only rule is the transparency one. A PNG with a transparent area keeps it if you export as PNG or WebP, and loses it in a JPG, because JPG has no alpha channel to put it in. **Can I combine screenshots into one image?** Yes, and screenshots are the case worth setting up properly. Two shots of the same window are already the same width, so switch the size handling to 'do not adjust' and stack them. Nothing gets resampled and the text stays exactly as sharp as it was on screen. Pick a background colour that contrasts with the screenshots themselves. Two white screenshots on a white background merge into one image with no visible boundary, which reads as a rendering bug rather than as a deliberate stack. **Does merging reduce image quality?** It does not have to. There are two places quality can go, and you control both. Resampling: Only happens if you ask for it. 'Do not adjust' and 'crop the biggest' both draw every image at its original pixel scale, so nothing is stretched or squeezed.. Re-encoding: Happens once, at export, for the whole canvas. Choose PNG and it is lossless. Choose JPG and you take a single generation of loss no matter how many images went in. One thing that is not a quality setting: export size. Full size hands back the merge exactly as composed, while 1080p and 720p scale the finished image down for an upload limit. All three are free. **Can I reorder the images before merging?** Drag the tiles. The strip under the preview holds every image you have added, in the order they will be drawn, and dragging one to a new position updates the preview immediately. Each tile has its own remove button too, so a wrong file does not mean starting the merge over. **What happens when my images are different sizes?** You choose, because there is no single right answer. A phone photo next to a thumbnail wants different handling than two screenshots of the same window, and a tool that picks for you gets it wrong half the time. Reduce the biggest: The default. Large images scale down to match the smallest, so nothing is invented and nothing comes out soft.. Magnify the smallest: Small images scale up to match the largest. Keeps the output big, at the cost of some softness in the small ones.. Crop the biggest: Nothing is resized at all. Larger images lose their edges instead, cropped from the centre, so every pixel stays exactly as sharp as it started.. Do not adjust: Every image keeps its own size and the canvas grows to fit them all. 'Constrain proportions' decides what happens to the leftover space: on, each picture keeps its aspect ratio and the gaps get filled with your background colour. Off, images stretch to fill their cell exactly. **Can I have a transparent background?** Yes. Pick Transparent and the gaps between your images stay see-through, which is what you want when the merged image is going on top of something else, like a slide or a dark-themed post. There is one catch worth knowing, and the tool will tell you about it rather than letting you find out from the file: JPG has no transparency. Ask for a transparent JPG anywhere and you get black or white corners. Here, a transparent background downloads as PNG instead, and a line on screen says so. If you would rather have a colour, there are six one-tap presets (white, black, red, green, blue) plus a picker for your own hex, so a merge can match your brand instead of approximately matching it. **Which file formats can I download?** PNG, JPG, and WebP where your browser can write it. PNG is the safe default: it is lossless and it is the only one of the three that can hold a transparent background. You also pick the export size. Full size gives you the merged image exactly as composed; 1080p and 720p scale it down for a post or an upload limit. Picking full size does not re-compress anything, so nothing is lost to a second encode. **Is it free, and is my image private?** It is a free image merger in the plain sense of the word: free at every size, with no account, no watermark and no upgrade. 1080p used to sit behind a Pro subscription and a mandatory sign-in; that is gone, because charging for a larger copy of the image you just made is a gate on the exact thing this page promises. And private in the strong sense rather than the marketing sense: merging runs on a canvas in your browser, so your images never reach a server of ours. There is nothing for us to keep. ### Collage Maker https://www.piknova.com/tools/collage-maker The image merger opened on its collage templates: Even, Big left, Big right, Big top, Big bottom and Mosaic, in square, 4:5, 9:16, 16:9 or 4:3, for any number of photos. Each photo can be zoomed, dragged, flipped, rotated, rounded or faded inside its cell. Exports PNG, JPG or WebP at up to 4000 px on the longest side, free. It does not add text or stickers. **What is a photo collage maker?** A photo collage maker arranges several photos into one image using a layout, so you post or print one file instead of a stack. The good ones also crop each photo to fit its cell, which is the tedious part by hand. **Is the collage maker free?** Yes, completely. Every template, every shape and every export size is free, with no watermark and no account needed. It can be free because your browser does the work. The photos never leave your device, so there is no server cost to charge you for. **How many photos can a collage have?** There is no limit on the count. Even grows the grid as you add photos (nine make a 3x3, sixteen a 4x4), and the other templates share the space left beside the big cell. The real limit is size. The collage stays within 4000 pixels on its longest side, so the more photos you add, the smaller each one comes out. **Can I make a collage on my phone?** Yes. Open this page in your phone's browser, tap to add photos from your camera roll, and the collage downloads to your phone like any other image. Dragging a photo inside its cell works with a finger too. If the screen feels cramped, the Horizontal and Vertical sliders do the same job. **How do I make a collage on iPhone?** The iPhone Photos app has no collage button. You have two options without installing anything. Shortcuts: Apple's Shortcuts app has a Combine Images action that joins photos in a row, a column or a grid. It works, but there are no templates and no way to frame each photo.. This page in Safari: Add photos from your library, pick a template, and save the result to Photos from the download. **Does Google have a collage maker?** Google Photos does: in the app, the Create menu has a Collage option. It is quick for a handful of photos, with a small set of layouts and few controls over cropping. Reach for a dedicated collage maker when you need a specific shape, like a 9:16 story, more photos, or control over which part of each photo shows. **Which collage template should I use?** Ask whether one photo is better than the rest. If it is, use a Big template and put it first. If they are all equal, use Even, and if the set feels stiff in a grid, try Mosaic. Then pick the side for the big cell by where people will look first. Big top suits a feed, where people scroll down; Big left suits a wide slide, where they read across. **Can I add text or stickers to my collage?** Not in the collage maker itself: it does the layout, the framing and the lines. Download the collage, then open it in Add Text to Image or Add Emoji to Photo for the finishing touch. ### Tap the Post (X) https://www.piknova.com/tap-the-post-x The splitter armed for X: one picture becomes the 4 tiles that preview as a single 2x2 block in the timeline. **What is the Tap the Post trend on X?** It is a post made of four images that are really one image cut into quarters. In the timeline X shows them as a small 2x2 grid with every tile cropped, so the picture reads as incomplete. Tapping it opens the tiles at full size and the whole image lands. The tap is the point. It turns a post that would have scrolled past into one people actually open, and an opened post is worth more to the algorithm than one that was merely seen. **What order do the four tiles go in?** X fills its grid in the order you attach the images, left to right and then top to bottom. So attach them like this: Top-left. Top-right. Bottom-left. Bottom-right Get the order wrong and the preview looks scrambled, which kills the reveal. Your downloaded tiles are already numbered 1 to 4 in this exact order. **What kind of image works best for Tap the Post?** One obvious subject with room around it. The timeline preview crops every tile, so anything living near an edge is the first thing to disappear. Works: High-res landscape shots, strong color, a subject somewhere near the middle.. Struggles: Text-heavy graphics, busy collages, and anything where the detail sits at the edges.. Size: Start at 2000px wide or more. Each tile is a quarter of your original, so a small source goes soft fast. **Does the trend work on desktop, or only in the app?** Both. On x.com the four images show up in the same 2x2 preview and a click opens the full viewer, so the reveal reads the same on a laptop as it does on a phone. Most people will still meet your post on mobile, so it is worth checking your tiles at phone size before you publish. **Do I need Photoshop or an app to make one?** No. Drop your image in above, keep the grid layout, and download all four tiles as a zip. No crop coordinates, no design software, and no account at all. There is no download limit, guest or signed in, and no watermark on the tiles. The split runs on a canvas in your browser, so your image is never uploaded to us in the first place. **Does splitting cost me image quality?** Every tile is cut straight out of your original at the resolution it already had, so nothing is upscaled or stretched. PNGs stay PNG. JPEGs are re-encoded at high quality. The only real variable is your source. A 1000px wide photo produces 500px tiles, and X will show those soft no matter what we do. ### Screenshot Editor https://www.piknova.com/tools/screenshot-editor The full editor behind most of these pages: text, arrows, shapes, emoji, freehand drawing, crop and blur on any screenshot or photo. **How do I edit a screenshot online?** Take your screenshot, then press Ctrl+V on this page. The editor opens with your image in it. Pick a tool from the rail on the left, mark up the part that matters, and adjust the size and colour until it reads clearly. When you are happy with it, hit Download. There is no account step and no watermark. **Can I edit the text that is already in my screenshot?** No, and no honest screenshot text editor can do it cleanly. A screenshot is pixels, so the words in it are not text any more. What you can do is add your own text on top, or cover the old line with a filled box and type the replacement over it. That takes about five seconds and it looks the same in the exported file. **Can I add arrows, circle something or highlight part of a screenshot?** Yes to all three. Arrows and lines, rectangles, circles and stars, and a semi-transparent highlighter. Drag one onto the image and it becomes a layer you can move, recolour or remove later. **Can I draw on a screenshot freehand?** Yes. The pen tool draws in whatever colour and thickness you set, the marker draws semi-transparent so what is underneath still shows, and the eraser takes back the stroke you regret without undoing everything else. **Can I add emoji to a screenshot?** Yes. Open the emoji tool, search or browse, then click one to drop it in the middle or drag it exactly where you want it. Each one lands as a layer you can resize, rotate, mirror, fade or swap for a different emoji without losing the size and angle you set. They come from Twemoji rather than your system font, which matters more than it sounds: a font emoji is drawn by whichever device opens it, so the same file would look different on a Mac, a PC and an Android phone. This way what you place is what everyone sees. **Can I crop a screenshot here?** Yes. Select the image and use Crop in its toolbar. It lives with the picture rather than in the tool rail on purpose, so when there are two images on the canvas there is no doubt about which one you are trimming. **How do I hide a password or a card number?** Pick up the Redact tool and drag over it. Five styles are there, and for a password or a card number the one to reach for is Solid: a blur or a mosaic is a transformation of the pixels that were there and a weak one can sometimes be partially reversed, while a filled box has nothing underneath it to recover. The panel tells you that at the moment you choose, not afterwards. **Is my screenshot uploaded anywhere?** No. Your browser opens the file and draws on it locally. Nothing is sent to a server, which is also why it is instant on a big image and why it keeps working if your connection drops. **Is it really free, with no watermark?** Yes. No signup, no export limit, no logo in the corner. Since the work happens on your computer rather than ours, there is no per-image cost for us to pass on. **What file types can I edit?** PNG, JPG and WebP, up to 25 MB. Screenshots are almost always PNG, which is also the best format to export back to because it keeps text and interface edges sharp. **Will my transparent PNG stay transparent?** Yes, as long as you export as PNG or WebP. If you pick JPG the editor warns you first, because JPG has no transparency and those areas would come out white. We will not make that swap quietly. **Does it work on a phone?** Yes, though it is more comfortable on a larger screen. Tap to place text and use the on-screen keyboard as normal. The layers panel is hidden on narrow screens to leave room for the image. **Can I come back and finish later?** Within the same browser, yes. Your work in progress is kept locally, so a refresh or an accidental tab close does not lose it. Clearing your browser data does, and it does not follow you to another device, because it was never on our servers to sync. ### Background Remover https://www.piknova.com/tools/background-remover Removes the background from a photo, logo or product shot and hands back a transparent PNG. The model runs in the browser, so the picture is never uploaded. **How do I remove the background from an image for free?** Drop your JPG, PNG or WebP onto the box at the top of this page, choose what you want behind the subject, and press Remove background. A few seconds later you get a preview with the original next to the result, and a download button under it. There is no account, no credit system and no watermark. The first run downloads the model to your browser, which takes a moment; every run after that starts immediately. **Are my images uploaded to a server?** No. The segmentation model runs inside your browser, on your own hardware. Your file is read from your device, processed in memory, and handed back. Nothing is transmitted, so nothing can be stored, logged or leaked, and closing the tab erases every trace. The one thing that does travel over the network is the model itself, which your browser fetches from a CDN the first time you use the tool and then caches. That is a download to you, not an upload of your picture. **Why is the first run slow?** Because your browser is fetching roughly 40 MB of neural network before it can do anything with it. That is the price of not sending your image to a server, and it is paid once: the files are cached afterwards, so the second image starts instantly. If you are on mobile data and the download matters, wait for wifi. The progress bar tells you which phase you are in so you are never staring at an unlabelled spinner wondering whether it has hung. **Can it make an image background transparent?** Yes, and that is the default. Leave the background on Transparent and you get a PNG with a real alpha channel, including the partial transparency along antialiased edges, so it sits cleanly on any colour you drop it onto. If you uploaded a JPG, the download comes back as a PNG, because JPEG cannot store transparency at all. The tool flags that next to the background options before you press anything. **Does it work on logos, text and product photos?** Logos and products are the easiest cases, and usually come out clean on the first pass. Text keeps its edges, and white areas inside a mark survive, which is the thing a colour-based eraser gets wrong. For a marketplace listing, pick White rather than Transparent. Amazon and eBay want pure white behind the product, and the White option here is exactly RGB 255,255,255 rather than an off-white that looks right and gets flagged. **Will my JPG still be a JPG?** If you choose a solid background, yes. A JPG comes back as a JPG, a PNG as a PNG, a WebP as a WebP. Changing your file's type without being asked is a good way to break somebody's upload form. The single exception is a transparent result from a JPG, which has to become a PNG because JPEG has no alpha channel. The alternative would be painting a white background behind your subject and calling it transparent, which is how a logo ends up in a white box on a coloured header. **How good is it on hair, fur and fine edges?** Better than you expect and not as good as a person with an hour. Individual strands of hair against a clean background usually survive with their soft edges intact. Hair against a busy background of a similar colour is where it starts guessing, and sometimes guesses wrong. Zoom in and see for yourself, because the result opens in an editor rather than as a preview. There is a shrink slider for a leftover halo and erase and restore brushes for anything the model got plainly wrong, so a nearly-right cut-out is a thirty second fix rather than a reason to start again somewhere else. What a brush cannot do is invent detail the model never captured. If a strand of hair was blended into a background of the same colour, painting it back gives you a blob in the shape of your brush. For a hero image at that level, the honest answer is still a different source photo or a person with an hour. **Can I fix it if the cut-out is not quite right?** Yes, and the tools are already on screen when the cut-out arrives. There is a shrink slider for a leftover halo, a soften slider for a hard edge, and erase and restore brushes for anything the model plainly got wrong. Change the background while you work, because a fringe that is invisible against one colour is obvious against another. The edits change the transparency rather than the picture, so you can still swap the background afterwards without losing them. Undo, redo and a reset back to the original cut-out are all there. **What formats and sizes can I download?** PNG, JPG or WebP, at original size or scaled down to roughly 2000, 1200 or 600 pixels on the longest edge. The Download button opens both lists, and it only offers sizes that are actually smaller than your image, because a menu that offers to enlarge something it cannot enlarge is just a broken row. Every combination is free. There is no HD tier and no watermark on the small ones. The one option that can be unavailable is JPG while the background is transparent, because JPEG has no alpha channel; pick a background colour and it comes back. **Is there a limit on how many images I can do?** No. No daily cap, no credits, no account, no watermark, and no resolution tier. Your device does the work, so there is nothing for us to ration. Ten images at a time, in one run. Drop a batch here and you get the same queue, or start from the bulk background remover, which is this same tool on a page written for a folder of listings rather than a single photo. The editing on this page is there too: when a batch finishes, any one of the results can be opened and its edges fixed without rerunning the other nine. **What is the largest file I can use?** 25 MB per image, with a 25 megapixel ceiling on top of it. That covers phone and DSLR photos comfortably. The pixel limit is lower here than on the other tools because this one holds the decoded image, a full-size mask and an RGBA composite in memory at once. Past that a browser can run out of memory in a way that shows up as a blank tab rather than an error, so the tool declines the file instead of gambling with your work. ### Bulk Background Remover https://www.piknova.com/tools/bulk-background-remover The background remover on a batch: up to 10 JPG, PNG or WebP images, one background (transparent, white, black or a colour) across the queue, and a zip at the end. The model runs in the browser, so nothing is uploaded. Any single image can be reopened and corrected by hand without rerunning the batch. It does not resize. **How do I remove the background from multiple images at once?** Drop all of them onto the box above, or open the picker and select up to 10 files. They arrive as a queue of cards, you pick one background for the whole set, and you press the button once. When the run finishes you stay on the same screen with every result in front of you, so you can check the edges before anything is downloaded. That is the step most bulk tools skip. **Can I fix one image if the model got its edges wrong?** Yes, and this is the part worth knowing about. Click any finished image and it opens with the edge tools on it: a shrink slider for a leftover halo, a soften slider for a hard edge, and erase and restore brushes for anything the model plainly got wrong. Apply, and only that file is rebuilt. Nothing else in the batch is touched or re-run. The cut-outs are kept after the run, so a correction costs a few seconds rather than a second pass of the model over all ten images. **Can one image have a different background from the rest?** Yes. Open that image, switch to the Background tab, and pick what you want behind it. The rest of the batch keeps whatever you chose for the run. A file given its own background keeps it: changing the batch background later re-applies to everything except the images you decided about individually, so a deliberate choice is never quietly overwritten. **Can I change the background after the batch has run?** Yes, and it does not run the model again. Pick a different background and a button appears offering to apply it to the finished images; it re-composites them from the cut-outs already in memory, which takes seconds rather than another full pass. **How many images can I do in one batch?** Up to 10, at up to 25 MB each. Past 10 a segmentation queue stops being one you wait out, and it also stops being a set anybody will genuinely check one by one. There is no cap on how many batches you run. Nothing is counted and nothing is stored between runs, so 10 at a time in rounds is how you handle 50 or 100. **Do I get one zip, or do I have to save each file?** Both are there. One button packs the whole batch into a zip with the original filenames, and every row also has its own download if you only wanted three of the twelve. **Is a batch of product photos uploaded anywhere?** No, and this is the part bulk usually changes. Most batch removers need your files on their servers to segment them, which is why they show you an upload bar. This one runs the model in your own browser, so the batch never leaves the tab and there is nothing to delete afterwards. The practical proof: once the model has cached, turn off your network and the batch still runs, editing included. **What happens if one image in the batch fails?** That row is marked failed with a reason, and the rest of the queue keeps going. A corrupt file, a format the browser cannot decode, or an image past the 25 megapixel ceiling stops itself and nothing else. You can remove it and re-run, or just download what worked. A batch where one bad file discards the other nine results is not a batch tool. **Is the bulk background remover free, and do I need an account?** Free, and no. No signup, no watermark on any output, no daily limit, no per-image credits, and no paid tier that unlocks more files or the editing tools. That is possible because your own machine does the segmenting. A hundred batches cost us exactly what zero do, so there is nothing to recover and nothing to gate. ### Add Text to Image https://www.piknova.com/tools/add-text-to-image Puts text or a caption on an image, with fonts, colour, outline and free placement. **How do I add text to an image?** Drop your image on the box above, or press Ctrl+V to paste one. The editor opens with the text tool already selected, so click where you want the words and start typing. Then set the font, size and colour from the toolbar above the image, and turn on the outline if the background is busy. When it looks right, press Download. There is no account step and no watermark. **Is it really free to add text to a photo online?** Yes. No signup, no export limit, no logo stamped in the corner. The work happens in your browser rather than on our servers, so there is no per-image cost for us to pass on to you. **Can I add text to a JPG or a PNG?** Both, plus WebP, up to 25 MB. You get the same format back that you put in, unless you deliberately pick a different one on the way out. We will not quietly turn your PNG into a JPG, because that would flatten any transparency it had. **Can I edit the text that is already in the picture?** No, and nothing that does this cleanly is doing what it claims. An image is pixels, so the words inside it are not text any more, they are a pattern of colours. What you can do is cover the old line with a filled box and type the replacement over it. That takes about five seconds and looks identical in the exported file. **Do I have to download any software?** No. It runs in the tab you are reading this in. There is nothing to install, nothing to update, and it keeps working if your connection drops halfway through, because the image was never going anywhere. **How do I make text readable on a busy photo?** Turn on the outline. A stroke around the letters separates them from whatever is behind, which is why every subtitle on every video does it. If the background is really chaotic, put a semi-transparent rectangle behind the text as well and the words will sit calmly on top of it. **Can I add more than one piece of text?** As many as you want. Each one is its own layer with its own font, size, colour and position, which is how you get a heading, a subheading and a small attribution line all doing different things on the same image. **Will my text look the same on other people's devices?** Yes. The fonts are drawn into the image when you export, so what you download is a picture of your text rather than an instruction for someone else's computer to render it. If a font ever fails to load while you are working, the editor tells you which one and what it substituted, rather than quietly changing your typeface. **Is my photo uploaded anywhere?** No. Your browser opens the file and draws on it locally. Nothing is sent to a server, which is also why it is instant on a large image and why nobody here can see what you were working on. **Does it work on a phone?** Yes, though a bigger screen is more comfortable for fine positioning. Tap to place a text box and use the on-screen keyboard as normal. The layers panel is hidden on narrow screens to leave room for the image. ### Add Emoji to Photo https://www.piknova.com/tools/add-emoji-to-photo Drops emoji stickers on a photo, movable and resizable, whether you are covering a face or reacting to one. **How do I add an emoji to a photo?** Drop your photo on the box above, or press Ctrl+V to paste one. The editor opens with the emoji picker already showing, so search for the emoji you want or browse the grid. Click one to drop it in the middle, or drag it straight where you want it. Resize it from the corners, rotate it from the handle above, then press Download. No account, no watermark. **How do I cover a face with an emoji?** Place an emoji, then drag a corner handle to scale it up until it covers the face. A smiley, sunglasses or a solid circle all work. Because the export is flattened, the face is not hidden underneath the emoji in the downloaded file, it is not in the file at all. And the original never leaves your device, which is the part that matters if you are anonymising a photo in the first place. **Is it free, with no watermark?** Yes. No signup, no export limit, no logo in the corner. The work happens in your browser rather than on our servers, so there is no per-image cost for us to pass on. **Will the emoji look the same on other people's phones?** Yes, and this is worth knowing about. Emoji from a system font are drawn by whichever device opens them, which is why the same message can look cheerful on an iPhone and slightly unhinged on an older Android. These are drawn from Twemoji and painted into the image when you export, so the picture you download is the picture everyone sees. **Can I add more than one emoji?** As many as you like. Each is its own layer with its own size, angle and transparency, and you can reorder them so one sits in front of another. **Can I add a heart, a smiley or a specific emoji?** Search for it by name in the picker. Hearts, smileys, fire, sunglasses, arrows, flags and hundreds more are in there, and the ones you use most float to the top of the panel next time. **Will the emoji look blurry if I make it big?** No. They come from vector artwork and are drawn at the size you export, so an emoji covering half a photo is as crisp as a small one in the corner. **Can I add an emoji to a screenshot?** Yes, exactly the same way. If you are marking up a screenshot rather than decorating a photo, the annotation page pairs emoji with arrows, boxes and labels, which is usually what that job needs. **Is my photo uploaded anywhere?** No. Your browser opens the file and draws on it locally. Nothing is sent to a server, which is why it is instant on a large photo and why nobody here can see what you were editing. **Does it work on a phone?** Yes. Tap an emoji to place it, then drag it into position and pinch or drag a corner to size it. A larger screen is more comfortable for fine placement, but the whole job works on a phone. ### Image Overlay https://www.piknova.com/tools/image-overlay Overlays one image on another, a logo on a photo or two photos superimposed, with drag, scale and opacity. **How do I overlay one image on another?** Drop the picture that goes underneath on the box above. The editor opens with the image panel already showing, so upload the image you want over it there. Click it to place it in the middle, or drag it straight where you want it. Then resize from the corners, rotate, set the transparency if you want the two to blend, and press Download. **Can I overlay a transparent PNG on a photo?** Yes, and the transparency survives. Export as PNG or WebP and your logo keeps its transparent background with no white box around it. If you pick JPG the editor warns you first, because JPG cannot hold transparency and those areas would come out white. **Can I superimpose two images?** Yes, that is the same job under an older word. Superimposing two images online means putting one over the other on a shared canvas, which is what happens the moment you add the second file. Drop the top layer's opacity if you want them to blend rather than one covering the other. **How many images can I stack?** As many as the canvas can hold. Each is its own layer with its own position, size, angle and opacity, and you can reorder them from the layers panel so one sits in front of another. **Can I make the top image semi-transparent?** Yes. Select it and use the opacity control in its toolbar. Anywhere between 20% and 60% is the useful range for blending two photos; above that it mostly just covers, and below it tends to disappear. **What is the difference between this and the image merger?** This one stacks: pictures share a canvas and can cover each other. The merger tiles: pictures sit beside each other in a grid with nothing overlapping. If you are making a before-and-after pair or a four-up thumbnail, the merger is one step instead of four. **Can I crop the image I added?** Yes, and only that one. Select the overlay and Crop is in its own toolbar rather than in the tool rail, which is deliberate: when there are two pictures on the canvas, a crop button that does not say which one it means is a guess waiting to go wrong. **Do both images get uploaded anywhere?** Neither one does. Your browser opens both files and composites them locally. Nothing is sent to a server, which is why it stays fast with two large photos and why nobody here can see what you combined. **What formats can I use?** PNG, JPG and WebP, up to 25 MB per file, and you can mix them: a JPG photo with a PNG logo on top is the most common combination there is. **Is the download full resolution?** Yes, at the size of the background image, and you can export at double that if you need it. There is no quiet downscale and no watermark. ### Add Watermark to Image https://www.piknova.com/tools/add-watermark-to-image Adds a text or logo watermark to a photo, with opacity, rotation and tiling. We add no watermark of our own to the export. **How do I add a watermark to an image?** Drop your photo on the box above. The editor opens with the text tool already armed, so click where you want the mark and type your name, handle or copyright line. Then set the size, drop the opacity to somewhere around 40%, rotate it if you want it diagonal, and press Download. For a logo instead, open the image panel and upload your PNG. **Is it free, and does it add its own watermark?** Free, and no. No signup, no export limit, and nothing of ours added to your image. A watermarking tool that stamps its own logo on your photo has misunderstood the assignment. **Can I watermark a JPG, PNG or WebP?** All three, up to 25 MB. You get the same format back unless you deliberately pick another on the way out, so a watermarked PNG stays a PNG and keeps any transparency it had. **Can I add a repeating watermark across the whole image?** Not as one action, no. This places a single mark where you put it. You can duplicate the layer a few times and space them out by hand, which is fine for three or four and tedious past that. A proper tiled watermark is on the roadmap. **Can I watermark a whole folder of photos at once?** Not yet. This is one image at a time. Batch watermarking is a different tool and it is on the list; saying so now is better than you finding out after dropping 200 files in. **Will a watermark stop people stealing my photos?** It stops casual reuse, which is most reuse. It does not stop someone determined, because a mark in a corner can be cropped and a faint one can be cloned out. A diagonal mark across the middle is much harder to remove and much uglier, which is the trade-off: use it on proofs, not on published work. **How faint should a watermark be?** Between 30% and 60% opacity suits most images. The test is whether you can read it without looking for it, and stop noticing it once you have. If the background is busy, turn on the text outline rather than raising the opacity, or you will end up with a mark that fights the photo. **Is my original photo uploaded anywhere?** No, and this is the point on a watermarking page. Your browser opens the file and draws on it locally. The unprotected original is never sent to a server, never sits in a temporary folder somewhere, and never reaches us. **Can I put a watermark on a photo from my phone?** Yes. Tap to place the text, type, and drag it into the corner. A larger screen is easier for fine placement, but there is nothing to install either way. ### Add Arrow to Image https://www.piknova.com/tools/add-arrow-to-image Draws arrows on an image or a screenshot to point at the thing you are talking about, with colour, thickness and curve. **How do I add an arrow to an image?** Drop your image on the box above, or press Ctrl+V to paste one. The editor opens with the arrow tool already armed. Press where the arrow should start, drag to whatever it points at, and release. Then set the colour, thickness and style from the toolbar above the image, and press Download. **Can I add more than one arrow?** Yes, as many as you need. Each one lands selected so you can adjust it straight away, then press the arrow tool again for the next. Each arrow is its own layer, so you can recolour, resize or delete any one of them later without disturbing the rest. **Can I move an arrow after I have drawn it?** Yes. Switch to the select tool, click the arrow, and drag either end to change where it starts or what it points at. This is the thing most arrow tools cannot do, because they turn the arrow into pixels the moment you release the mouse. **Can I make the arrow dashed, or change its thickness?** Both. Solid or dashed, and any thickness you like. The arrowhead scales with the line so a thick arrow still ends in a proportionate head rather than a needle. **Can I add an arrow to a JPG or a PNG?** Both, plus WebP, up to 25 MB. You get the same format back unless you deliberately choose another on the way out, so a transparent PNG stays transparent. **Is it free, with no watermark?** Yes. No signup, no export limit, no logo in the corner. The work happens in your browser rather than on our servers, so there is no per-image cost for us to pass on. **Can I point the arrow in any direction?** Any direction and any angle, because the direction is just where you dragged. There are no eight fixed compass directions to choose from, and no preset arrow shapes to rotate. **Is my image uploaded anywhere?** No. Your browser opens the file and draws on it locally. Nothing is sent to a server, which matters when the thing you are pointing at is inside a private dashboard or an internal tool. **Does it work on a phone?** Yes. Drag with your finger from the tail to the target. A larger screen makes precise aiming easier, but there is nothing to install either way. ### Add Shapes to Image https://www.piknova.com/tools/add-shapes-to-image Draws rectangles, circles and boxes on an image to frame or circle part of it. **How do I add a shape to an image?** Drop your image on the box above, or press Ctrl+V to paste one. The editor opens with the shape tool already armed. Pick the shape you want from the toolbar above the image, then drag on the picture to size it. Choose outlined or filled, set the colour, and press Download. **Which shapes can I add?** Rectangles, rounded rectangles, circles and ellipses, triangles, pentagons, hexagons and stars. Each can be outlined or filled, in any colour and at any opacity. There are no speech bubbles or callout shapes, which is worth saying because a lot of pages imply them. **How do I draw a circle around something?** Pick the circle, set it to outlined rather than filled, then drag from just outside the thing you want to highlight. Free-dragging gives you an ellipse, which is usually the right shape around a word or a button; hold while dragging for a perfect circle. Go thicker with the outline than feels right if the image will be viewed small. **How do I cover up something private?** Draw a rectangle over it and set it to filled. That is safer than blurring: the exported image is flattened pixels, so there is nothing under the box for anyone to peel off, whereas a light blur is sometimes partially reversible. And because nothing is uploaded, the version with the details still visible never leaves your machine. **Can I add a star shape?** Yes, stars are in the shape list, along with triangles, pentagons and hexagons. Drag to size, and they can be outlined or filled like everything else. **Can I resize a shape after drawing it?** Yes. Switch to the select tool, click the shape, and drag a handle. You can also rotate it, recolour it, change the corner rounding, fade it, or send it behind another layer. Nothing is baked into the picture until you export. **Can I add several shapes at once?** As many as you need. Each one lands selected so you can adjust it right away, then press the shape tool again for the next. Each one is its own layer with its own colour, opacity and position. **Is it free, with no watermark?** Yes. No signup, no export limit, no logo in the corner. The work happens in your browser rather than on our servers, so there is no per-image cost for us to pass on. **Is my image uploaded anywhere?** No. Your browser opens the file and draws on it locally. Nothing is sent to a server, which is why it is instant on a large image and why nobody here can see what you were covering up. ### Annotate Screenshot https://www.piknova.com/tools/annotate-screenshot Marks up a screenshot with arrows, boxes, highlights and labels, which is the bug-report and tutorial workflow. **How do I annotate a screenshot?** Take your screenshot, then press Ctrl+V on this page. The editor opens with your image in it, and the whole markup kit is on the rail on the left. Arrow the thing you mean, box the region around it, add a label saying what is wrong or what to click, then download it or copy it straight back to your clipboard. No account step and no watermark. **Do I need to download or install anything?** No. It runs in this tab. Nothing to install, nothing to update, no browser extension, and it keeps working if your connection drops, because the screenshot was never going anywhere. **Is it free?** Yes. No signup, no export limit, no logo in the corner. The work happens on your computer rather than ours, so there is no per-image cost for us to pass on. **Can I add arrows, boxes and labels?** All three, plus circles, stars, a highlighter, a pen, emoji and a second image dropped on top. Each lands as its own layer, so you can move it, recolour it, send it behind something or delete it later without touching the screenshot underneath. **Can I highlight part of a screenshot?** Two ways. The marker draws semi-transparent freehand, so text under it stays readable, which is the closest thing to a real highlighter. Or draw a rectangle with a semi-transparent fill over the region, which is tidier for a block of text. **How do I hide a password or a card number?** Use the Redact tool and choose Solid. There is a real blur and a real pixelate in there too, and for a password neither is the one to reach for: both are transformations of the pixels that were there, and a weak one can sometimes be partially reversed, whereas a filled box exports flat with nothing under it. Drag a shape over the field or trace around it freehand. **Can I paste the annotated screenshot straight into a ticket?** Yes. Use Copy instead of Download and the marked-up image goes back to your clipboard, so it can be pasted directly into most issue trackers and chat apps. Clipboard in, clipboard out, and nothing ever hits your Downloads folder. **Is my screenshot uploaded anywhere?** No. Your browser opens the file and draws on it locally. Nothing is sent to a server, which is also why it is instant on a 4K screenshot and why nobody here could look at your dashboard even if they wanted to. **Can I crop the screenshot before annotating it?** Yes, and for tutorials you usually should. Select the image and use Crop in its own toolbar. It lives with the picture rather than in the tool rail on purpose, so when there are two images on the canvas there is no doubt about which one you are trimming. **Can I come back and finish later?** Within the same browser, yes. Work in progress is kept locally, so a refresh or an accidental tab close does not lose your markup. Clearing your browser data does, and it does not follow you to another device, because it was never on our servers to sync. ### YouTube Banner Maker https://www.piknova.com/tools/youtube-banner-maker Opens the editor on a 2560 x 1440 YouTube channel banner with a guide layer marking what TV, desktop, tablet and mobile show, including the 1546 x 423 safe area. The guide is left out of the download. It does not upload to YouTube. **How do I make a YouTube banner?** Press Start editing above for a blank 2560 x 1440 banner, or Upload an image to start from a picture. The guide on the canvas marks what each screen shows. Add your channel name and logo inside the box labelled Text and logo safe area, fill the rest with background, then press Download. The guide is left out of the file. **Is this YouTube banner maker free?** Yes. No sign up, no watermark, no export limit. The banner is made in your browser rather than on our servers, so there is no per-banner cost for us to pass on. **What size should a YouTube banner be?** 2560 x 1440 pixels, 6 MB or less, with text and logos inside the centred 1546 x 423 safe area. The minimum YouTube accepts is 2048 x 1152. The editor opens on 2560 x 1440, so you start at the right size without typing anything. **Will the guide lines show up in my banner?** No. The guide is a layer marked as not part of the download, and every export skips it, whether you download, copy or share. If you want to see the banner without it while you work, hide it from the layers panel. **Should I download my banner as PNG or JPG?** PNG for flat colour and lettering, where it keeps edges sharp. JPG for anything built on a photo, because a full-size PNG of a photo can go past YouTube's 6 MB limit. If YouTube rejects the file as too large, download it again as JPG at actual size. The export menu shows how big the last download was, so you can check before you upload. **Do you have YouTube banner templates?** One, and it is the one that matters: the safe-area template the editor opens on, with every device crop marked. There is no gallery of ready-made designs to pick from. The point is to build your own banner on top of the guide, with your picture and your channel name where every screen will show them. **How do I upload my banner to YouTube?** Open YouTube Studio, go to Customization, then Branding, and under Banner image choose Upload. YouTube shows a preview of the crops before you publish. This tool does not connect to your YouTube account, so that last step is yours. **Can I make a YouTube banner on my phone?** Yes, though a bigger screen is more comfortable at 2560 x 1440. The guide works the same on a phone. The layers panel is hidden on narrow screens to leave room for the canvas, so hiding or reordering the guide is easier on a laptop. **Is my image uploaded anywhere?** No. The Upload an image button opens the picture in your browser, and the banner is drawn there. Nothing is sent to a server, which is also why nobody here can see what you were making. ### Crop Image https://www.piknova.com/tools/crop-image Trims the edges off an image with a draggable frame and ratio presets, in the browser, at the original resolution and format. It cannot add pixels back beyond the original picture. **How do I crop an image online?** Drop your image on the box at the top of this page, or press Ctrl+V to paste one. It opens with the crop frame already around it. Drag the handles in until only the part you want is inside the frame, press Apply or Enter, and download. No account, no watermark. **Is this image cropper really free?** Yes. No signup, no watermark, no trial, and no limit on how many photos you crop. The work runs in your browser, so each crop costs us nothing, and there is nothing to charge you for. **Does cropping reduce image quality?** Not the pixels you keep. Exported at Actual size, a PNG comes back pixel-for-pixel identical inside the frame. A JPG or WebP is re-encoded once, at quality 92 by default, and the slider goes up to 100. The picture does get smaller, because a crop removes pixels, so a very tight crop will look soft if you stretch it to fill a big screen. **Will my photo stay in the same format?** Yes. The export defaults to the format you dropped in, so a JPG comes back a JPG. You can pick a different one in the download menu if you want to, but it never changes on its own. **Can I undo a crop after pressing Apply?** Yes, right up until you export. The crop hides the edges rather than deleting them. Select the picture, open the crop frame again from its toolbar, and pull it back out, or press Reset to put the frame around the whole original. Ctrl+Z works too. **Is my image uploaded anywhere?** No. Your browser opens the file and crops it on your device. The photo never reaches Piknova's servers, and the download is redrawn from scratch, so location data and camera details from the original do not come with it. **How do I crop a picture on iPhone?** In the Photos app, open the picture, tap Edit, tap the crop icon, drag the corners and tap Done. If the photo is on a computer instead, or you want to keep the crop adjustable, this page does the same job in Safari. **How do I crop a picture on Android?** In Google Photos, open the picture, tap Edit, then Crop, drag the corners and tap Save copy. Other gallery apps put crop under Edit too. This page also works in Chrome on Android if the built-in editor is not doing what you need. **Can I keep the same shape as the original photo?** Yes. Set the Crop ratio menu to Original and the frame keeps the photo's proportions while you drag any handle. Set it back to Free to trim each edge on its own. **Does cropping make the file smaller?** Usually, because there are fewer pixels to store. It is not a reliable way to hit an upload limit, though. If the file has to be under a specific size, run it through the image compressor after cropping. **What files can I crop, and how big?** PNG, JPG and WebP, up to 25 MB each. Drop the file, pick it from the file dialog, or paste it straight from your clipboard. **Does it work on a phone?** Yes. The frame's handles respond to touch and you can pinch to zoom the canvas. A larger screen makes precise trims easier on a big photo, but a quick crop on a phone works fine. ## Blur, redaction and privacy ### Blur Image https://www.piknova.com/tools/blur-image Blurs part of an image or all of it, selected by shape or freehand lasso, in five styles: blur, pixelate, solid, sticker and glitch. **How do I blur part of an image?** Drop your image on the box above, or press Ctrl+V to paste one. The editor opens with the redact tool already armed and set to blur. Drag a selection over the area you want hidden, pick blur, pixelate or a solid block, and set the strength. Download when it reads the way you want. No account, no watermark. **Can I blur the whole image instead of one part?** Yes. Drag one region from corner to corner and the whole picture blurs at whatever strength you set. The tool is built around regions because that is what people usually want, a sharp photo with one thing missing from it, but nothing stops a region being the entire frame. **Is my image uploaded anywhere?** No. Your browser opens the file and does the masking locally. Nothing is sent to a server, nothing is stored, and nothing is sitting somewhere waiting to be deleted. That matters more here than on any other tool on this site, because the file you are editing is the one you decided was too sensitive to post. **Can a blurred image be un-blurred?** Partially, sometimes, depending on how it was done. A light blur over small text can be meaningfully recovered by deconvolution. A heavy blur over a large area destroys enough information that it is not practical. If what you are hiding would genuinely hurt you if it came out, use a solid block instead: that one has nothing left underneath it to recover. **Is pixelating safer than blurring?** No, and this is the common mistake. Pixelation averages a fixed block of pixels, which makes it reversible by brute force when the attacker knows what kind of thing they are looking for, such as a number, a name, or text in a known font. Public tooling for exactly that has existed since 2020. Use pixelation when you want something to look censored, not when it needs to stay hidden. **What is the safest way to hide something in an image?** A solid block, exported flattened. There is no data underneath a filled rectangle in a flattened file, so there is nothing to reconstruct. Everything else is a trade-off between how safe it is and how natural the result looks, and the redact panel tells you that where you pick rather than afterwards. **Can I blur multiple areas at once?** Yes. Add as many regions as you need. Each one lands selected so you can line it up, then pressing the tool again starts the next, so a photo with four faces is four drags. Each region is a separate mask you can move, resize, restyle or delete without affecting the others. **Can I blur a face automatically?** Not yet. Right now you drag over each face yourself, and an ellipse is the shape to use because a hard rectangle over someone's head looks obviously placed. The face page opens with that ellipse already armed at a heavier blur, so it is the faster way in. Automatic detection is being built and it will run in your browser like the rest of the tool. **Can I blur text in a screenshot?** Yes, and pasting is the fast way to do it: take the screenshot, press Ctrl+V here, drag over the line, pick your method. For anything genuinely sensitive like a token or an account number, use a solid block rather than a blur, because text is the case where a weak blur is most recoverable. **Does the download still contain the GPS coordinates?** No. The export is redrawn onto a canvas and re-encoded from raw pixels, so the EXIF block in the original, including GPS coordinates, device model and timestamp, does not carry through. Worth knowing because blurring pixels does nothing to metadata, and a photo with a hidden face can otherwise still say precisely where it was taken. **What file types can I blur, and how large?** PNG, JPG and WebP, up to 25 MB. Screenshots are usually PNG, which is also the best format to export back to. If you export a transparent PNG as JPG the editor warns you first, because JPG has no transparency and those areas would come out white. **Can I undo a blur before downloading?** Yes. Nothing is applied permanently until you export. Move a region, change the method, adjust the strength, or delete it entirely, and the original pixels are still there underneath until the moment you download. **Does blurring reduce the quality of the rest of the image?** No. Only the regions you selected are altered. Everything outside them comes out at the resolution and quality it went in at, and the export is full size with no watermark. **Is it free, and do I need an account?** Free, unlimited, no account, no watermark, no export cap. The work happens on your computer rather than ours, so there is no per-image cost for us to pass on to you. **Does it work on a phone?** Yes, though a larger screen makes precise selection easier. Tap and drag to place a region as normal, and the freehand mode works with a finger for the shapes a rectangle cannot cover. ### Blur Face in Photo https://www.piknova.com/tools/blur-face-in-photo Opens on an ellipse at a heavy blur, for hiding faces in a photo before it goes anywhere public. **Can facial recognition still identify a blurred face?** Not from the blurred face itself, if the blur is heavy. But identification does not depend on the face alone. Systems and people both match on body shape, clothing, posture, the location, the other people in the frame and the text around the image, and a blur touches none of that. The practical risk is simpler than any of that: the same person unblurred in another photo from the same set, or in the account that posted it. That is how most blurred faces get identified, and it is not a technical attack at all. **How do I blur several faces in one photo?** One drag each. A region lands selected so you can adjust it, then pressing the tool again starts the next face with the same settings. Each face becomes its own layer, so you can adjust or delete one without touching the rest, and the layers panel gives you a count to check against the number of people in the photo. **Should I blur a child's face or cover it with an emoji?** Either works, and they cover equally well. An emoji sticker and a solid fill both paint over the region without reading it, so there is nothing underneath in the export. A heavy blur leaves the picture looking more like a photograph. Choose on how you want the photo to read, then spend the saved worry on the uniform crest and the house number in the background, which are usually the bigger problem. **Does blurring a face remove the location from the photo file?** Blurring does not, but exporting from here does. Blurring changes pixels, and the GPS coordinates, device model and timestamp live in the file's metadata rather than in the picture. The export is redrawn onto a canvas and re-encoded from raw pixels, so that metadata does not survive into the file you download. **Does it detect faces automatically?** Not yet, and that is the honest answer rather than a soft one. Several tools ranking for this term do detect faces for you. Here you place each region yourself, which is slower on a crowd and better on the cases detection misses: profiles, partial faces, someone at the edge of the frame, and anything that is not a face but still identifies a person. Detection is being built and will run in your browser like everything else. **Can I blur a face on my phone?** Yes. Tap and drag to place the oval, then use its handles to size it. A larger screen makes precise placement easier, but the whole editor runs in a mobile browser, which is where most of the photos being blurred were taken. **Is the photo uploaded anywhere?** No. Your browser opens the file and blurs it locally. Nothing is sent to a server, nothing is stored, and nothing is waiting somewhere to be deleted. On a page about photos of other people's children, that is the part worth checking on any tool, not just this one. **Is blurring faces free, and do I need an account?** Free, unlimited, no account, no watermark and no export cap. The blurring happens on your device rather than ours, so there is no per-photo cost for us to pass on to you. ### Blur License Plate https://www.piknova.com/tools/blur-license-plate Covers a number plate in a car photo before a listing, a claim or a post. **Do I actually need to blur my license plate before posting?** For a public listing or a public post, yes, and it takes four seconds. Plate lookup services are cheap and widely available, and they return the make, model, year and often the tax and inspection history of the vehicle. The real risk is the combination rather than the plate alone. A plate plus a house number in the same photo, or plus a street sign in the next photo of the same set, turns a car listing into an address. Marketplaces recommend covering it for exactly that reason. **What else should I hide besides the plate?** The house number and the street sign first, since those are what turn a vehicle into a location. Then the VIN visible at the base of the windscreen, any permit or workplace sticker in the window, the dealership frame around the plate, and reflections in the paintwork and glass, which are the ones almost nobody checks. The section above is the full list in the order worth doing it. **Is a blur or a black box better for a number plate?** A black box, marginally, and on a plate the visual cost is almost nothing because the plate is a small rectangle in the frame. A blur transforms the characters rather than removing them, and seven characters in a known font at a known aspect ratio is close to the ideal case for a reconstruction. This page opens on a blur at high strength because that is what people search for, and the solid style is one click away in the panel. **Does it find the plate automatically?** No. You drag over it yourself, which on a plate takes about as long as reading this sentence, since it is a single high-contrast rectangle you can see immediately. Automatic detection is being built for faces and plates alike and will run in your browser like the rest of the tool, but it is not here yet and the page is not going to imply otherwise. **How do I blur plates in a whole set of listing photos?** One at a time, and do all of them. There is no batch mode here, so twelve photos is twelve passes, each about ten seconds. Skipping one is worse than skipping none, because a single visible plate makes the other eleven pointless. If that is too slow for a large set, photograph the car somewhere that is not your home instead, which removes the reason for most of the covering. **Does the photo still say where it was taken?** Not after you export it from here. Phone photos carry GPS coordinates, the device model and a timestamp in their metadata, and blurring pixels does nothing to any of that. The export is redrawn onto a canvas and re-encoded from raw pixels, so the metadata block does not carry through. On a photo taken on your own driveway that is arguably more important than the plate itself. **Can I blur a plate on my phone?** Yes. Tap and drag a rectangle over the plate, then use the handles to fine-tune it. A plate is a small target, so pinch to zoom in first if you are working on a phone screen. The whole editor runs in a mobile browser, which is where the photo already is. **Is it free, and is my photo uploaded?** Free, unlimited, no account, no watermark and no export cap, and nothing is uploaded. Your browser opens the photo and blurs it locally, so a picture that shows your car and your house is not sent to anyone in order to stop showing them. ### Blur Text in Image https://www.piknova.com/tools/blur-text-in-image Hides names, addresses, emails or account numbers in a screenshot or a photo of a document. **Can blurred text be read?** Sometimes, and more often than people expect. It depends on how hard the blur was compared to the size of the characters. A light blur over small text can be meaningfully recovered by deconvolution, especially when the attacker knows the font and roughly what kind of string they are looking for. A heavy blur over a large region is a different story: too much information is genuinely gone for a reconstruction to be practical. The problem is that the difference between those two cases is a slider position most people never touch. **Is a black box better than a blur for hiding text?** Yes, and it is not close. A solid fill does not look at the pixels underneath it, so on a flattened export there is nothing left to reconstruct, at any zoom, with any tool. A blur and a mosaic are both transformations of the original pixels, which means some amount of the original is still encoded in what you exported. That is why the solid block is what this page arms by default. **How do I hide an API key in a screenshot?** Paste the screenshot here with Ctrl+V, drag the solid block over the whole key including its prefix, and export. Cover the prefix too: a visible sk_live_ or ghp_ tells anyone reading which service the key belongs to and how many characters they are looking for. And rotate the key anyway if it was ever visible in something you sent, because a covered screenshot does not undo the moment it was on screen in a call. **Does blurring an email address stop it being scraped?** A solid block does, because there is nothing left in the file to read. A light blur may not, since the same reconstruction that works on other short strings works on an address, and addresses are unusually guessable: the format is fixed, the domain is often visible from context, and the local part is frequently a name that appears elsewhere in the same screenshot. **Can it find the sensitive text for me automatically?** No. There is no OCR here and no automatic detection of keys or account numbers, so you drag over each one yourself. That is a real limitation and worth stating plainly rather than implying otherwise. It is also the reason each block lands selected: if you are placing them by hand, lining one up with the text should not mean going looking for it first. **Is my screenshot uploaded anywhere?** No. Your browser opens the file and covers the text locally. Nothing is sent to a server, nothing is stored, and nothing is sitting somewhere waiting to be deleted. That matters more on this page than almost anywhere else on the site, because the thing you are covering is frequently a live credential. **Can I cover several lines of text at once?** Drag one block over the whole area if the lines are adjacent, or one per line if there is content between them you want to keep. Either way, each block is a separate layer you can move, resize or delete without touching the others. **Do I need an account to hide text in a screenshot?** Free, unlimited, no account, no watermark and no export cap. The work happens in your browser rather than on our servers, so there is no per-image cost for us to pass on to you. ### Redact Image https://www.piknova.com/tools/redact-image Covers information with a solid block, which is the only one of these methods that cannot be reversed. **Is a black box over text actually removing it?** It depends entirely on the file format, which is the single most important thing on this page. In a PDF or any layered format, no: the rectangle is one object and the text is another, and both travel in the file. Anybody can select, copy or extract the text underneath. In a flattened image, yes. The export here composites the rectangle into the pixels, so the covered area is genuinely black in the file you download. There is no layer to remove because the format has nowhere to keep one. **What is the difference between redacting and blurring?** A blur transforms the pixels; a redaction replaces them. That means a blur always leaves some encoded trace of the original, and how recoverable it is depends on the strength and on what was underneath. A solid fill leaves nothing, because it never looked at the pixels underneath in the first place. For a document, that difference is the whole job, which is why this page arms the fill and not the blur. **Can I redact a scanned document?** Yes, and a scan is the easiest case, because it is already a flat picture with no text layer to worry about. Drop the scan, black out each field, and export. If you scanned to PDF rather than to an image, export the pages as PNG first, which also gets you out of the layered-file problem in one step. **Is this good enough for legal or compliance work?** We can tell you the technical fact and not the legal one. Technically, the covered pixels are replaced and the export is flattened, so the file you download does not contain what you covered, which is the requirement most redaction rules are trying to express. Whether that satisfies your regulator, your court, your client or your own policy is a judgement for whoever owns that requirement. We are not making a certification and you should be suspicious of any free browser tool that does. **Can I redact several fields on the same page?** Yes, one drag each. A new box lands selected so you can line it up with the field, then pressing the tool again starts the next. Each one is its own layer while you work, listed in the layers panel, which is the fastest way to confirm your count before you export. **Does the redacted file still contain the original photo data?** No. Beyond flattening the redactions, the export is re-encoded from raw pixels, so the EXIF block from the original, including the timestamp, the device model and any GPS coordinates, does not carry through. That matters for a photographed document, which otherwise arrives saying exactly when and where it was photographed. **Can I use a colour other than black?** Yes. The fill comes from the same palette as the rest of the editor, so white on a dark screenshot or grey as a visible placeholder are both available. Black is the default because on a printed page it is the one convention nobody misreads as a highlight or an annotation. **Is it free, and is the document uploaded?** Free, unlimited, no account and no watermark, and nothing is uploaded. Your browser opens the file and does the redaction locally, so the document you were careful enough to redact is not sent to a third party in order to redact it. That is the part worth checking on any tool you use for this, including this one. ### Censor Image https://www.piknova.com/tools/censor-image Puts bars, pixels or stickers over anything that should not be in the frame. **What is the difference between censoring and redacting an image?** In practice, the stakes and the intent. Censoring is about the look: a bar over a spoiler, a mosaic on a logo, a sticker over a face in a group photo. Whether the pixels underneath survive is often beside the point, and sometimes the whole point is that everyone can see something was covered. Redacting is about the information. The word comes from documents, it assumes somebody may try to get the covered part back, and the only acceptable result is that they cannot. If that describes what you are doing, the redaction page is the one written for it. **How do I make a classic black censor bar?** It is already armed. Drop your image and drag a rectangle over what you are covering: the solid black fill is the default style on this page, so the first thing you draw is the bar. If you want a different colour, open the fill picker and choose one, and every bar after it comes out the same colour. **Can I censor with an emoji instead of a bar?** Yes. Switch the style to Sticker and pick any emoji, and the region fills with it. The strength slider controls how big each one is, so a low value tiles a row of small ones along a long field and a high one drops a single large emoji over a face. It covers just as completely as a black bar, since neither one looks at the picture underneath. **Will the censored part show if someone zooms in?** Not with a solid fill or an emoji. Both of those paint over the region without reading it, so there is nothing underneath in the exported file at any zoom level. A blur or a mosaic is different: those transform the pixels rather than replacing them, so zooming shows exactly what the transformation left behind, which on a heavy setting is nothing useful and on a light one can be more than you intended. **Can I censor more than one thing in the same picture?** Yes, one drag each. A new bar lands selected so you can line it up, then pressing the tool again starts the next. Each bar is a separate layer you can move, recolour, restyle or delete on its own. The layers panel lists them, which is worth a glance before you post if you were covering several names. **Does censoring the image reduce its quality?** No. Only the regions you covered change. Everything outside them exports at the resolution and quality it came in at, full size, with no watermark. If you need the file smaller afterwards that is a separate job, and the compressor does it without touching the bars. **Is the censor tool free, and is there a watermark?** Free, unlimited, no account, no watermark and no export cap. The censoring happens on your computer rather than on a server, so there is no per-image cost for us to pass on to you. **Can I undo a censor bar before downloading?** Yes. Nothing is applied permanently until you export. Move a bar, resize it, change its colour or its style, or delete it entirely, and the original pixels are still sitting underneath until the moment you download. ### Pixelate Image https://www.piknova.com/tools/pixelate-image Pixelates a region or the whole image, with the block size under your control. **How do I pixelate just one part of an image?** Drag over that part and nothing else. The mosaic is already the armed style when the editor opens, so the first thing you drag becomes a pixelated region and everything outside it stays at full sharpness. Add a second region and a third if there is more than one thing, and each stays independently editable. **What block size should I use?** For privacy, large enough that you cannot locate the features you are hiding: no eyes in a face, no word boundaries in a line of text. If you can see where the words break, it is not big enough. For the retro look, much smaller. You want the picture to still read as a picture, drawn in blocks. The slider scales the blocks to the size of the region, so covering a whole photo needs a higher position than covering one small number did. **Can pixelation be reversed?** For text, effectively yes, and this surprises people. Because each block is a simple average, someone who knows what kind of string they are looking for can render candidates, pixelate them identically and compare until it matches. For a face it is far harder, since there is no finite set of candidates to test. If the thing underneath would genuinely hurt you if it came out, use a solid block, which has nothing underneath it at all. **How do I get a retro 8-bit pixel look?** Drag one region from corner to corner so the whole frame is covered, then bring the block size down until the subject is still recognisable. Start with a simple, high-contrast picture, because busy scenes turn to mush at any setting. Note that this gives you big blocks and the original colours: it does not reduce the picture to a sixteen-colour console palette, which is the other half of what people mean by 8-bit. **Can I pixelate the whole image at once?** Yes. Drag a single region from one corner of the picture to the other and the entire frame is treated. This is the only page in this group where that is the normal thing to do rather than an edge case, which is most of why it exists separately. **Which format should I export a pixelated image as?** PNG. A mosaic is nothing but hard edges between flat blocks, which is exactly what JPG compression handles worst, so a pixelated JPG comes back with visible fuzz around every block boundary. PNG keeps the edges crisp. If the file needs to be smaller afterwards, compress it as a separate step. **Is my picture uploaded when I pixelate it?** No. Your browser opens the file and builds the mosaic locally. Nothing is sent to a server, nothing is stored, and the export is re-encoded from raw pixels, so the GPS coordinates and device details in the original do not carry through either. **Do I need an account to pixelate an image?** Free, unlimited, no account, no watermark and no export cap. The work happens on your computer rather than ours, so there is no per-image cost for us to pass on to you. ### Redacted Text Generator https://www.piknova.com/tools/redacted-text-generator Replaces typed text with block characters and exports it as a PNG, so the blocks render the same everywhere instead of turning into tofu boxes. **What is a redacted text generator?** A tool that swaps the characters you type for solid block characters, so the result looks like a redacted document and can be copied and pasted anywhere text goes. It is a text transformation rather than an image edit: what comes out is a string, and you can put it in a chat message, a wiki page or a code comment. **Can someone read the text back out of the black bars?** Not with the four block styles. Those replace each character with a different character, so the output genuinely does not contain what you typed, and there is nothing to strip or decode. With strikethrough, yes, easily. That style attaches an overlay mark to your original letters, which are all still there. The tool warns you the moment you pick it, because it is the one option here that looks like a redaction and is not. **Why do the bars not match the length of my words?** On purpose, and it is the main thing this tool does differently. A one-for-one replacement publishes the exact length of every word you hid, and word lengths plus context are often most of a guess. The lengths are varied by default and you can shuffle them again or turn the behaviour off, though the section above explains why leaving it on is the better default. **How do I keep the last four digits visible?** Move the reveal slider to 4. Every word then keeps its last four characters and hides everything before them, which is the exact shape a payment or identity verification asks for when it wants to see a card. Read the output before you send it, since every word keeps its ending, not just the one you were thinking about. **Where can I paste the redacted text?** Anywhere that takes plain text: Discord, Slack, wikis, Markdown, code comments, spreadsheets, email. The one thing to watch is fonts. A face without block glyphs renders them as empty boxes, which looks broken rather than censored, so if you are pasting into a branded template or a PDF export, download the PNG instead. **Is there a redacted font I can install instead?** No, and this is worth clearing up because a lot of people search for one. The effect is character substitution, not a typeface. A font that drew every letter as a black box would still be carrying your original text underneath, which is the strikethrough problem in a worse form: it would look hidden and would copy, search and index as the original. **Can I download the redacted text as an image?** Yes. The PNG button draws the result in a monospace face at your screen's real pixel density, so the bars are solid and evenly spaced rather than striped. Use it wherever you do not control the font, or where the destination takes a picture and not text. **Is anything I type here sent to a server?** No. The substitution and the PNG both happen in your browser, and nothing you type leaves the page. That matters more here than on most tools, since the text you are redacting is by definition the text you did not want somewhere else. ## Compress and resize ### Image Compressor https://www.piknova.com/tools/image-compressor Compresses JPG, PNG and WebP down to an exact target in KB (20, 25, 50, 100, 200 or any number you type), on files up to 25 MB. **How do I compress an image to 25 KB?** Select your image, switch to the 'By file size' tab, pick 25 KB or type it in, then press Compress. The result is guaranteed to be under 25 KB, not near it. For a small image like a headshot or a scanned signature, 25 KB is reachable at full resolution. For a full-size camera photo it usually is not, so the tool shrinks the dimensions too and tells you on the result screen exactly what size it ended up. **Can it compress an image to 20 KB or below 100 KB?** Yes, and to anything in between. The presets are 20 KB, 25 KB, 50 KB, 100 KB, 200 KB, and the box next to them takes any number from 5 KB to 5000 KB, so 60 KB, 90 KB or 350 KB are all one keystroke away. Every target is treated as a ceiling. We search for the highest quality that fits under it rather than aiming for it and hoping, which is what stops you from getting a 104 KB file back from a 100 KB request. **Are my images uploaded to a server?** No. Compression happens in your browser using the canvas it already ships with. Your file is read from your device, compressed in memory, and handed back. Nothing is transmitted, so nothing can be stored, and closing the tab erases every trace. **What is the largest file I can compress?** 25 MB per image, which covers full-resolution phone and DSLR photos. There is also a 50 megapixel ceiling, because a heavily compressed panorama can be a small file that still needs 200 MB of memory to decode. Past either limit, a browser can run out of memory in a way that shows up as a blank tab rather than an error, so the tool declines the file instead of gambling with your work. **Will compressing ruin the quality?** At the default level, no. Most photos lose more than half their weight before there is anything to see, and the before-and-after preview is there so you can check rather than take our word for it. At 100%, or at a very aggressive size target, yes, and visibly. Skies and shadows band, fine texture smears. That is what maximum compression is, and we would rather say so than call it 'optimized'. **Will my PNG stay a PNG, and keep its transparency?** Yes to both. A PNG goes in and a PNG comes out, with its alpha channel intact, including the partial transparency along antialiased edges. Nothing is flattened onto a white background, because you never asked for a background. PNG has no quality setting for us to turn down, so we compress it by reducing how many distinct colours it contains. PNG's compression works by finding repetition, and fewer colours means far more of it. At the lightest setting the change is invisible; push the level up and you will start to see banding in gradients, which is the honest cost of a smaller PNG. One consequence worth knowing: a PNG that was already run through an optimizer can come back slightly larger, because a browser writes full-colour PNGs rather than the palette-indexed ones those tools produce. If that happens the tool shows you both sizes so you can keep whichever is smaller. **Does it change the width and height of my image?** Not unless it has to. Compression keeps your dimensions exactly as they were. The one exception is a size target that no quality setting can reach at full resolution, where the alternative is missing the number you asked for. When that happens the result panel says so and shows the new dimensions, so it is never something you find out later. **Is there a limit on how many images I can compress?** No daily cap, no account, no watermark. Your device does the work, so there is nothing for us to ration. Fifty images at a time, in one run. Drop a batch here and you get the same queue, or start from the bulk image compressor, which is this same tool on a page written for a folder rather than a file. ### Bulk Image Compressor https://www.piknova.com/tools/bulk-image-compressor The compressor on a batch: up to 50 JPG, PNG or WebP images at once, one compression level or one KB target applied across the queue, and a zip at the end. Each file keeps its own format. It does not resize to set dimensions. **How do I compress multiple images at once?** Drop all of them onto the box above, or open the picker and select up to 50 files. They arrive as a queue of cards, you choose one compression level or one target in KB, and you press the button once for the whole batch. You can keep adding files after the queue is open, and you can remove any you changed your mind about. Nothing runs until you tell it to. **How many images can I compress in one batch?** Up to 50, at up to 25 MB each. Past 50 the list stops being something you can actually read, which is the limit we hit long before the browser does. There is no cap on how many batches you run. Nothing is counted, nothing is stored between runs, and no batch costs us anything, so there is nothing for us to ration. **Can every image in the batch come out under the same size in KB?** Yes. Switch to 'By file size' and type the number once. It is applied per file as a ceiling, so a batch at 100 KB gives you files that are each under 100 KB rather than an average. Each file gets its own search for the highest quality that still fits, because a screenshot and a camera photo need very different settings to land on the same number. Anything already under the target is left as it is. **Do I get one zip, or do I have to save each file?** Both are there. The results screen has a single button that packs the whole batch into one zip with the original filenames, and every row also has its own download if you only wanted three of the twelve. **Can the batch mix JPG, PNG and WebP files?** Yes, and you do not need to sort them first. Each file is compressed as the format it arrived in and comes back as that same format, so the PNGs keep their transparency and the JPEGs stay JPEGs. Expect uneven results in a mixed batch, and that is the format talking rather than the tool. PNGs of photographs shrink far less than the same pictures as JPG, because a photograph in a lossless format is a photograph in the wrong format. **Is a batch of photos uploaded anywhere?** No, and this is the part bulk usually changes. Most batch compressors need your files on their servers to do the work, which is why they show you an upload bar. This one decodes and re-encodes every file in your own browser, so the batch never leaves your device and there is nothing to delete afterwards. The practical proof: turn off your network after the page has loaded and the batch still runs. **What happens if one file in the batch fails?** That row is marked failed with a reason, and the rest of the queue keeps going. A corrupt file, a format the browser cannot decode, or an image past the pixel ceiling stops itself and nothing else. You can remove it and re-run, or just download what worked. A batch where one bad file discards the other nineteen results is not a batch tool. **Is the bulk image compressor free, and do I need an account?** Free, and no. No signup, no watermark on any output, no daily limit, and no paid tier that unlocks more files or better quality. Every setting is available on every run. That is possible because your own machine does the compressing. A hundred batches cost us exactly what zero do, so there is nothing to recover and nothing to gate. ### Image Resizer https://www.piknova.com/tools/image-resizer Resizes by pixels, centimetres, millimetres or inches with a DPI setting, locking aspect ratio, for print sizes and upload forms. **How do I resize an image to exact pixels?** Drop your image in, leave the unit on px, and type your number into the width box. With the aspect ratio locked the height fills itself in, so a 1080 wide Instagram post takes one keystroke and a click. If you need both numbers to be exact and they do not match your image's proportions, turn the ratio lock off. Be aware that is a stretch rather than a resize, so crop to the right shape first if the result matters. **How do I resize an image in cm or mm?** Switch the unit to cm or mm and type your measurement. A DPI control appears next to the fields, because a physical size only becomes a pixel count once you say how many pixels fit in an inch. Use 300 for anything being printed and 96 for anything staying on a screen. The tool shows you the pixel result under the fields as you type, so a 35 × 45 mm passport photo at 300 DPI visibly becomes 413 × 531 pixels rather than happening behind your back. **What DPI should I use, and does it get saved?** 300 DPI for print, 96 for screens. And yes, it gets saved: the number you choose is written into the exported PNG or JPG, so opening it in Word, Photoshop or a print dialog gives you the physical size you asked for. WebP and AVIF have no standard field for it, so those come back with the correct pixel count and no tag. The tool says so on the result rather than leaving you to find out at the print shop. **Will resizing stretch or distort my image?** Not with the aspect ratio lock on, which is the default. Change one side and the other is derived from your original's proportions, so the image is only ever scaled. Turn the lock off and both fields become independent, which is the only way to get a distorted result here. The tool spells out which mode you are in underneath the fields. **Does resizing reduce quality?** Making an image smaller is close to free. Removing pixels does not harm the ones that stay, and we downscale in repeated halving steps rather than one jump, which is what keeps edges and small text sharp. Making one bigger is a different story. The detail was never captured, so enlarging can only interpolate, and the result will be softer than the original. The tool warns you before you download when your numbers are larger than the source. **Can I resize an image to a specific file size in KB?** Not here, and that is on purpose. This page changes dimensions. If a form is rejecting your upload for being over 30 KB or 100 KB, what you want is the image compressor, which searches for the highest quality that still fits under a size you type. The two work well back to back: resize to the dimensions you need first, then compress that result to the file size the form demands. **Can I resize a GIF, a HEIC photo, or an AVIF file?** AVIF, yes. Still GIFs, yes, and they come back as PNG because no browser can write a GIF. Animated GIFs, no: a canvas only ever sees the first frame, so we decline them rather than quietly flattening your animation into a still image. HEIC is the iPhone default and no browser can open it without a heavyweight decoder. Set your iPhone to Settings, Camera, Formats, Most Compatible, or share the photo to Files and pick JPEG, then drop it back here. **Can I resize several images at once?** Yes. Fifty images at a time, in one run, with no daily cap and no account. Drop a batch here and you get the same queue, or start from the bulk image resizer, which is this same tool on a page written for a folder rather than a file. The batch page is also where the part that only matters for many files is explained: what 'the same size' means when the queue holds portraits and landscapes, and which of the three modes answers the question you are actually asking. **Are my images uploaded to a server?** No. Decoding, resampling and encoding all happen in your browser using the canvas it already ships with. Your file is read from your device, resized in memory, and handed back. Nothing is transmitted, so nothing can be stored, and closing the tab erases every trace. ### Bulk Image Resizer https://www.piknova.com/tools/bulk-image-resizer The resizer on a batch: up to 50 JPG, PNG, WebP, AVIF or GIF images at once, and a zip at the end. One setting across the queue, in one of three modes: scale everything by a percentage, fit every file inside a maximum width and height, or force exact dimensions on all of them. Each file keeps its own format. It resizes in pixels and cannot target a file size in KB, which is the compressor's job. **How do I resize multiple images at once?** Drop all of them onto the box above, or open the picker and select up to 50 files. They arrive as a queue of cards, you choose one of the three size modes and type your numbers once, and you press the button once for the whole batch. You can keep adding files after the queue is open, and you can remove any you changed your mind about. Nothing runs until you tell it to. **Can I resize multiple images to the same size?** Yes. Choose Exact, turn the aspect ratio lock off, and type the width and height. Every file in the queue comes out at those dimensions regardless of what shape it started as, which is what a product catalogue or a print sheet needs. Leave the lock on instead and the width becomes the instruction while each file's height follows its own proportions. That is the right answer far more often than it sounds, because upload forms and page layouts almost always specify a width. **How many images can I resize in one batch?** Up to 50, at up to 25 MB each. Past 50 the list stops being something you can actually read, which is the limit we hit long before the browser does. There is no cap on how many batches you run. Nothing is counted, nothing is stored between runs, and no batch costs us anything, so there is nothing for us to ration. **Do I get one zip, or do I have to save each file?** Both are there. The results screen has a single button that packs the whole batch into one zip with the original filenames, and every row also has its own download if you only wanted four of the thirty. **Can the batch mix JPG, PNG, WebP, AVIF and GIF files?** Yes, and you do not need to sort them first. Each file is resized and comes back as the format it arrived in, so the PNGs keep their transparency and the JPEGs stay JPEGs. Animated GIFs are the one exception, and they are refused rather than mishandled. A browser canvas only sees the first frame, so resizing one would hand you back a still image that still ends in .gif. **Can I resize a batch of images to 100 KB each?** Not with this tool, and it is worth being precise about why rather than pretending. Resizing changes an image's dimensions, measured in pixels. 100 KB is a file size, measured in bytes. Fewer pixels usually means fewer bytes, but there is no width you can type that guarantees a particular number of kilobytes, because that depends on the content of each photograph. The bulk image compressor is the tool for that: type a target in KB once and every file in the queue comes back under it. If you need both, resize here first and compress the results, in that order. **Is a batch of photos uploaded anywhere?** No, and this is the part bulk usually changes. Most batch resizers need your files on their servers to do the work, which is why they show you an upload bar. This one decodes and redraws every file in your own browser, so the batch never leaves your device and there is nothing to delete afterwards. The practical proof: turn off your network after the page has loaded and the batch still runs. **What happens if one file in the batch fails?** That row is marked failed with a reason, and the rest of the queue keeps going. A corrupt file, an animated GIF, a HEIC from an iPhone, or an image past the pixel ceiling stops itself and nothing else. You can remove it and re-run, or just download what worked. A batch where one bad file discards the other twenty-nine results is not a batch tool. **Is the bulk image resizer free, and do I need an account?** Free, and no. No signup, no watermark on any output, no daily limit, and no paid tier that unlocks more files or bigger dimensions. Every setting is available on every run. That is possible because your own machine does the resizing. A hundred batches cost us exactly what zero do, so there is nothing to recover and nothing to gate. ## Convert between formats ### Image Converter https://www.piknova.com/tools/image-converter The converter hub: reads JPG, PNG, WebP, AVIF and HEIC, writes JPG, PNG, WebP or AVIF, up to 50 files in one batch with one target across the queue. The pairs below have their own pages; the AVIF limits are on the PNG to AVIF page. It cannot write HEIC, because no browser can encode one. **Which formats can I convert between?** JPG, PNG and WebP, in any direction. That covers six conversions, and each one has its own page with the specifics for that trip. More formats are coming. The ones that need heavier decoding, like HEIC from an iPhone, need processing a browser cannot do on its own, so they arrive with server-side support rather than as a broken button. **Are my images uploaded to a server?** No. Conversion happens in your browser with the canvas it already ships with. Your file is read from your device, converted in memory, and handed back to you. Nothing is transmitted, so nothing can be stored or leaked. **What is the maximum file size?** 4.0 MB per file. Beyond that, an in-browser conversion of a large photo can exhaust memory on a mid-range phone, which fails as a blank tab rather than a clear error, so the tool declines the file instead. Compress or resize your image first, then convert it here. **What does the quality setting do?** It controls how hard the encoder compresses your output, and it starts at 75%. For photographs that is the sweet spot: small files, no visible difference. At 100% WebP switches to lossless mode and PNG is lossless regardless, so both come out pixel perfect. JPG at 100% is its best quality but still lossy, and we will not tell you otherwise. **Do I lose transparency when I convert?** Only when the target format cannot hold it. PNG and WebP both have a full alpha channel, so transparency survives between them. JPG has none, so transparent areas are placed on white before encoding, which is what you expect instead of the black rectangles some converters produce. **Is there a limit on how many images I can convert?** No. There is no daily cap, no account, and no watermark. Since your device does the work, converting a hundred images costs us exactly as much as converting none. ### HEIC to JPG Converter https://www.piknova.com/tools/heic-to-jpg Converts HEIC and HEIF photos from an iPhone into JPG, up to 50 at a time, in the browser, so nothing is uploaded. Keeps the full resolution and the rotation. It drops EXIF (date taken, camera, GPS), cannot convert the other way because no browser can write HEIC, and takes 16 MB and 50 megapixels per photo at most. **How do I convert HEIC to JPG?** Drop your HEIC files onto the box at the top of this page, or press the button and pick them from your device. JPG is already selected as the output, so you can convert straight away. You can select up to 50 photos at once. When they are done, save them individually or take the whole batch as a zip. There is no account step and no email step. **Is HEIC to JPEG the same as HEIC to JPG?** Yes, exactly the same. JPG and JPEG are two spellings of one format, and the only reason both exist is that old versions of Windows limited file extensions to three characters. The standard is JPEG; the extension became .jpg. This page converts to files ending in .jpg, which every piece of software on earth treats identically to .jpeg. If something specifically demands a .jpeg extension, renaming the file is enough, because nothing inside it needs to change. **Are my photos uploaded to a server?** No. The decoder runs inside your browser, so your photos are read from your own device, converted in memory, and handed back. Nothing is transmitted, which means nothing can be stored, logged or leaked, and closing the tab erases every trace. This is worth checking on any HEIC converter rather than taking on trust, and it is easy to check: open your browser's network tab while you convert. You will see the decoder download once and no request carrying your photo. **Will converting HEIC to JPG lose quality?** A small amount, and you control how much. Both formats are lossy, so re-encoding is a second compression pass, but most of what JPG discards is detail HEIC had already discarded. At the default 75% there is nothing visible to find on an ordinary photo. Resolution never changes. Every pixel of a 12 megapixel photo is still there afterwards. If you want the absolute maximum, open the settings and set quality to 100%, which makes the file noticeably bigger and the loss academic. **How big will the JPG be compared with the HEIC?** That depends on the quality setting, and it goes both ways. On a 2.9 MB, 12 megapixel photo the default 75% produced a 1.8 MB JPG, which is smaller than the HEIC. Turning quality up to 100% produced 9.4 MB on the same photo, which is more than three times it. The underlying fact is that HEIC is the more efficient format, so matching its quality costs more bytes in JPG. What that means in practice is that the default trades a little quality for a smaller file, and 100% keeps everything and pays for it. Neither is the right answer for everyone, which is why it is a setting. If the JPG has to come in under a specific number, the image compressor takes it down to an exact size in KB. **Does it keep the date, location and other EXIF data?** No. The JPG is written fresh from the decoded pixels, so the date taken, camera model, exposure settings and GPS coordinates are not carried across. Rotation is the exception: it is applied to the image itself, so your photos come out the right way up. Your original HEICs are not modified, so nothing is lost as long as you keep them. For a lot of people the stripping is the point, since it removes the GPS coordinates before a photo gets posted anywhere public. **What is the largest file I can convert?** 16 MB per photo, which comfortably covers everything an iPhone produces, including the 48 megapixel mode on recent Pro models. There is also a 50 megapixel ceiling on the image itself, because a decoded photo needs four bytes per pixel in memory and a very large one can take a phone's tab down with no useful error. Past either limit the tool declines the file and says so, rather than gambling and leaving you with a blank tab. **Does it work on iPhone, and on Windows?** Both, and on Mac, Android and Linux. It is a web page with a decoder inside it, so the only requirement is a current browser. On an iPhone you can convert straight from the camera roll in Safari and save the JPGs back to it. On Windows this is usually the better answer than installing Microsoft's HEIF and HEVC extensions, because those fix HEIC on that one computer while a JPG is readable everywhere you might send it. **Can it convert HEIF files as well?** Yes. HEIC is HEIF carrying an HEVC image, and the decoder reads the container rather than trusting the extension. Files ending in .heif go through the identical path, and a folder containing both converts in one batch with nothing to rename. **Is it really free?** Yes. No signup, no watermark, no daily limit, and no cap on how many photos you convert. Your device does the work, so a hundred conversions cost us exactly what zero do, and there is nothing for us to charge you for. ### Bulk HEIC to JPG Converter https://www.piknova.com/tools/bulk-heic-to-jpg The HEIC converter on a batch: up to 50 HEIC or HEIF photos at once, one JPG quality across the queue, each file converted in order in the browser with a per-file result, a stop button, and a zip at the end that keeps the original filenames. Same limits as the single page (16 MB and 50 megapixels per photo, EXIF dropped). It refuses a drop of more than 50 rather than trimming it, so a bigger folder is run in rounds. **How do I convert multiple HEIC files to JPG at once?** Drop all of them onto the box above, or open the picker and select up to 50. They arrive as a queue of rows, JPG is already selected, and you press the button once for the whole batch. You can keep adding photos after the queue is open, and remove any you changed your mind about. Nothing runs until you tell it to, and the JPGs come back individually or as one zip. **How many HEIC photos can I convert in one batch?** Up to 50, at up to 16 MB and 50 megapixels each. Past 50 the list stops being something you can actually read, which is the limit we hit long before the browser does. There is no cap on how many batches you run. Nothing is counted and nothing is stored between runs, so 100 photos is two runs and a thousand is twenty, with nothing asked of you in between. **Can I convert a whole folder of HEIC photos to JPG?** Yes. Select everything in the folder and drop it on the box, or use the picker and select all. If the folder holds more than 50, the box says so and asks for 50 at a time rather than quietly taking the first 50, so a folder of 80 is one run of 50 and one of 30. The zip you get back keeps every filename, so it drops back into the folder structure you took it from. **Does the folder have to be all HEIC, or can JPGs and PNGs be mixed in?** Mix them. Each file is read for what it actually is, not what its name says. HEICs and HEIFs are converted, anything already a JPG is passed through untouched and marked as such, and PNGs and WebPs become JPGs like the rest. The one thing to know: a transparent PNG cannot stay transparent as a JPG, so if the queue holds one you are told before the run that it will be flattened onto white. **What happens if one photo in the batch fails to convert?** That row is marked failed with a reason, and the rest of the queue keeps going. A file that stopped copying halfway, one that is over the size or pixel ceiling, or a .heic that has no HEIC inside it stops itself and nothing else. If it came off an iPhone, the usual fix is to copy that one file across again: a transfer that stops early leaves a file that still ends in .heic. Then remove the bad row, or just download the ones that worked. **Can I stop a batch partway through and keep what finished?** Yes. Stop is on the same button as convert. It lets the photo in progress finish, then stops, and every photo already converted stays on its row with its own download. The ones that never started stay queued, so you can change the quality and run those on their own. **Do I get one zip, or 50 separate downloads?** Both are there. The results screen has one button that packs the whole batch into a zip, with every photo keeping its original name and a .jpg extension, and every row also has its own download for when only a few of them were the point. Expect the zip to be a little smaller than the folder went in at the default 75%, and about three times bigger at 100%. The total is shown before you download it. **Is a batch of 50 iPhone photos uploaded anywhere to convert it?** No, and on a batch this is the part that changes most. Most bulk converters need your photos on their servers to do the work, which is why they show you an upload bar and why a batch of fifty takes minutes before the first result. This one decodes every photo inside your own browser, so nothing is transmitted and there is nothing on anyone's server to delete afterwards. The only download is the decoder itself, about two megabytes, once per session. After that the batch runs with the network off. **Is the bulk HEIC to JPG converter free, and is there a limit per day?** Free, and no. No signup, no watermark on any photo, no daily limit, and no paid tier that unlocks more files, full resolution or a higher quality. Every setting is available on every run, including the first. That is possible because your own machine does the converting. Fifty photos cost us exactly what one does, which is nothing, so there is nothing to recover and nothing to gate. ### PNG to AVIF Converter https://www.piknova.com/tools/png-to-avif Converts PNG to AVIF, up to 50 at a time, with a WebAssembly encoder that downloads once (3.5 MB) and runs in the browser, so nothing is uploaded. Keeps transparency and resolution. Lossy at the default 75%, lossless at 100%, though a lossless AVIF is usually larger than the PNG. Drops EXIF, ICC and DPI; takes at most 4 MB and 24 megapixels per file; about a second per image. **How do I convert PNG to AVIF?** Drop your PNG onto the box at the top of this page, or press the button and pick it from your device. AVIF is already selected as the output, so you can convert straight away. When it is done, the result tells you how much smaller the AVIF is than the PNG. Download it, or change the quality and convert again if you want it smaller or sharper. There is no account step and no email step. **How much smaller is an AVIF than a PNG?** Somewhere between a little and enormously, depending entirely on the picture. At the default 75%, a 1.5 MB illustration came out at 83 KB, a 1.3 MB logo at 21 KB, a 173 KB social card at 29 KB and an 81 KB screenshot at 11 KB. The floor case is a PNG that was already reduced to 256 colours: one of those went from 440 KB to 261 KB, which is a saving but not a dramatic one. Photographs, gradients and soft shadows shrink the most, because that is the content lossless compression handles worst and a video codec handles best. **Does converting PNG to AVIF keep transparency?** Yes. AVIF has a full alpha channel and this tool never paints a background under a format that supports one, so a transparent PNG becomes a transparent AVIF. At the default quality the alpha channel is compressed like everything else, so the antialiased edge pixels can shift very slightly. On a measured logo, 91.5% of pixels came back with exactly the alpha they went in with, and the rest were the soft rim. Set quality to 100 if you need those stored exactly. **Is PNG to AVIF lossless?** It can be. At 100% the encoder uses AV1's lossless mode and stops subsampling the colour, and the result is bit for bit identical to the PNG. Below 100% it is lossy, which is where all the size saving comes from. What surprises people is the result: a lossless AVIF made from a PNG is usually bigger than the PNG. In our measurements a 173 KB PNG became a 303 KB lossless AVIF, and a 440 KB one became 1.6 MB. PNG is already a very good lossless compressor for this kind of content. If you need lossless, keep the PNG and convert only what you are publishing. **What quality should I use for PNG to AVIF?** Leave it at 75% for a photograph, an illustration or a logo going on a web page. There is nothing visible to find at that setting, and resolution never changes: every pixel of a 2000 by 2000 image is still there afterwards. Go to 90% for interface screenshots or anything with small lettering, because sharp text on flat colour is where a lossy codec shows itself first. Use 100% only when you need a bit-for-bit copy, and expect that file to be larger than the PNG. Whatever you pick, the result shows the size before you download, so the cheap way to decide is to try two and read the number. **Are my files uploaded to a server?** No. The encoder runs inside your browser, so your file is read from your own device, converted in memory, and handed back. Nothing is transmitted, which means nothing can be stored, logged or leaked, and closing the tab erases every trace. This is easy to verify rather than take on trust: open your browser's network tab while you convert. You will see the encoder download once and no request carrying your image. **Can I save a PNG as AVIF straight from Figma, Canva or Preview?** Not at the time of writing. Figma exports PNG, JPG, SVG, PDF and WebP. Canva exports PNG, JPG, PDF, SVG and GIF. Preview on a Mac goes as far as HEIC. None of them has AVIF in the list, which is the whole reason a page like this exists. Export the PNG the way you normally would, drop it here, and download the AVIF. Keep the PNG: it is the master, and the AVIF is the copy you publish. **Can I convert more than one PNG at a time?** Yes, and there is a page for it: the Bulk PNG to AVIF Converter, linked under 'Convert a whole folder' just above. This page is written about a single file, the quality you pick for it and the size readout you get before you save. The bulk page runs the same converter on a queue of up to fifty, with one quality across the batch, a total for the whole folder, and a zip whose filenames still match your markup. **Why is this slower than the other converters?** Because AV1 is a video codec doing an exhaustive search that JPEG and PNG never attempt, and because no browser ships an AVIF encoder, so this page downloads one of about three and a half megabytes the first time you pick AVIF. After that first download it is cached for the session, so the next conversion starts immediately. Expect roughly a second for a typical image on a laptop and longer on a phone. That cost is exactly what buys you the file size. **What is the largest PNG I can convert?** 4.0 MB per file, and a ceiling of 24 megapixels on the image itself. The pixel limit is the one that matters: an AVIF encode holds several planes of the image in memory at once, so a very large photo can take a phone's tab down with no useful error. Past either limit the tool declines the file and says so, rather than gambling and leaving you with a blank tab. Resize it first, or convert it to WebP, which is cheaper to encode. **Can everyone open an AVIF file?** Every current browser can: Chrome since 2020, Firefox since 2021, Safari and iOS since 2022, Edge since January 2024. On a web page you control, that is effectively everyone. Off the web it is patchier. Windows needs the free AV1 Video Extension for previews, macOS reads AVIF from Ventura onward, and desktop editors are a mixed bag. Convert what you are publishing, and send people PNGs. **Can I convert AVIF back to PNG?** Yes, in the image converter, which reads AVIF as well as writing it. That direction is easy: every browser decodes an AVIF natively, so there is no encoder to download and the conversion is instant. Bear in mind what comes back. If the AVIF was made at 75%, converting it to PNG gives you a lossless copy of the compressed image, not the original detail. The only way back to that is the PNG you started with, which is a good argument for keeping it. **Can I convert PNG to AVIF from the command line instead?** For a build step, yes, and you probably should: sharp in a Node pipeline or avifenc from the libavif tools will do the same job on a server, with slower and better encoder settings than a browser tab can afford, and they can carry EXIF across. This page is for the other case, which is an image in front of you and no build step to put it through. **Is it really free?** Yes. No signup, no watermark, and no daily limit on how often you use it. Your device does the work, so the hundredth conversion costs us exactly what the first did, and there is nothing for us to charge you for. ### Bulk PNG to AVIF Converter https://www.piknova.com/tools/bulk-png-to-avif The AVIF converter on a batch: up to 50 PNG files at once, one quality across the queue, each file encoded in order in the browser, a total saving for the whole folder on the results screen, and a zip that keeps the filename stems (hero.png becomes hero.avif). Same limits as the single page (4 MB and 24 megapixels per file). It does not rewrite any markup, and a PNG already reduced to 256 colours barely shrinks. **How do I convert multiple PNG files to AVIF at once?** Drop all of them onto the box above, or open the picker and select up to 50. They arrive as a queue of rows, AVIF is already selected at 75%, and you press the button once for the whole batch. You can keep adding files after the queue is open, and remove any you changed your mind about. Nothing runs until you tell it to, and the AVIFs come back individually or as one zip. **How many PNGs can I convert to AVIF in one batch, and how long does it take?** Up to 50, at up to 4.0 MB and 24 megapixels each. Roughly a second a file on a laptop once the encoder has loaded, so a batch of 50 typical web images is about a minute, and longer for large illustrations or on a phone. If a folder holds more than 50, the box says so and asks for 50 at a time rather than quietly taking the first 50. There is no cap on how many batches you run, and the encoder stays loaded between them. **Can I give a few files in the batch a different quality?** Yes, in two runs. The quality is one setting for whatever the run touches, and the run touches everything unless you tick some rows, in which case it touches only those. So run the folder at the default, go back to the queue, tick the screenshots with small text, raise the quality, and run again. The rows you re-ran replace their earlier results. **Why did some PNGs in my batch barely shrink, or come back bigger?** Almost always because they had already been reduced to 256 colours by an export dialog. What is left in a file like that is mostly dithering noise, which a codec cannot predict, so it barely shrinks. Very small icons have little to give either, and an AVIF carries a few hundred bytes of container before the first pixel. The row shows the number either way. A file that came back bigger is one to keep as a PNG, or to re-export in full colour from the master and run again. **Can the folder mix PNG, JPG and WebP files?** Yes. Each file is read for what it actually is, and every one of them becomes an AVIF. The PNGs keep their transparency, the JPGs never had any to keep, and anything that is already an AVIF is passed through untouched and marked as such rather than re-encoded. **Do the filenames stay the same in the zip?** The stem does, with the extension swapped: hero.png becomes hero.avif, so markup that already names the PNG needs one new source line and no renaming. Characters that are not letters, digits, hyphens or underscores become underscores, which matters only if your asset names have spaces in them. **Is a folder of 50 PNGs uploaded to convert it?** No. No browser can write an AVIF, so this page downloads an encoder, about three and a half megabytes, once, and runs it inside your tab against files read off your own disk. Nothing is transmitted, and there is nothing on anyone's server to delete afterwards. After that first download the batch runs with the network off, which is the quickest way to check the claim. **What happens if one file in the batch fails?** That row is marked failed with a reason, and the rest of the queue keeps going. A corrupt export, a file over 4.0 MB, or an image past the 24 megapixel ceiling stops itself and nothing else. Remove it and re-run, or just download what worked. **Is the bulk PNG to AVIF converter free, and is there a limit per day?** Free, and no. No signup, no watermark on any file, no daily limit, and no paid tier that unlocks more files, full resolution or a higher quality. Every setting is available on every run, including the first. That is possible because your own machine does the encoding. Fifty files cost us exactly what one does, which is nothing, so there is nothing to recover and nothing to gate. ### JPG to PNG Converter https://www.piknova.com/tools/jpg-to-png Converts JPG to PNG losslessly, which is what you want before editing or when you need transparency support. **How do I convert JPG to PNG?** Drop your JPG file into the converter at the top of this page, or click the button to pick one. PNG is already selected as the output, so you can hit Convert straight away. When it finishes, the download button appears with the converted file. There is no queue, no email step, and no account. **Does converting JPG to PNG improve the quality?** No, and any tool that claims otherwise is selling something. JPG compression permanently removes detail when the file is first saved. Converting to PNG copies what is left, pixel for pixel, into a format that will not remove any more. That is still genuinely useful. It means the tenth save looks exactly like the first, which is not true if you keep working in JPG. **Will my PNG have a transparent background?** Not automatically. A JPG has no transparency to carry over, so the converted PNG looks identical to what you started with. What changes is that the file can now hold transparency, so you can erase the background in any editor and it will stay erased. **Why is my PNG so much bigger than the JPG?** Because PNG never throws anything away. JPG got small by discarding detail; PNG keeps every pixel of what remains. On photographs that regularly means a file three to five times larger. On screenshots and flat graphics the gap is much smaller, and PNG is usually the better format anyway. **Are my images uploaded to a server?** No. The conversion runs inside your browser using the canvas your browser already ships with. Your file is read from your own device, converted in memory, and handed back to you. Nothing is transmitted, which means nothing can be stored, logged, or leaked. It also means the tool keeps working if your connection drops halfway through. **What is the maximum file size?** 4.0 MB per file. Above that, converting in the browser gets memory-hungry enough to crash the tab on a mid-range phone, so the tool declines the file rather than gambling with it. If your image is larger, compress or resize it first and then convert it here. **Can I choose the output quality?** Yes. The gear icon next to the Convert button opens the quality control, which starts at 75%. That is the setting where files stay small and the difference stays invisible on a photograph. PNG has no lossy mode, so the setting has nothing to do here and every export is pixel perfect. **Is it really free?** Yes. No signup, no watermark, and no daily limit. Since the work happens on your device, converting an image costs us nothing to run, so there is nothing to charge you for. ### JPG to WebP Converter https://www.piknova.com/tools/jpg-to-webp Converts JPG to WebP, which stores the same photo in noticeably fewer bytes. **How do I convert JPG to WebP?** Drop your JPG file into the converter at the top of this page, or click the button to pick one. WebP is already selected as the output, so you can hit Convert straight away. When it finishes, the download button appears with the converted file. There is no queue, no email step, and no account. **Do all browsers support WebP?** Yes, for any browser someone is realistically using. Chrome, Edge, Firefox, and Opera have supported WebP for years, and Safari joined at version 14 in 2020. Browser support has not been a real objection since then. Software outside the browser is a different story. Some desktop editors and print workflows still will not open a WebP, which is why people convert them back. **How much smaller is WebP than JPG?** Google's own study puts lossy WebP 25 to 34% below JPG at equivalent quality. In practice it depends on the picture: busy, detailed photographs save less, and images with large smooth areas like skies or studio backgrounds save more. **Which quality setting should I use for WebP?** 75% is the right starting point for photographs on a website, and it is what this tool defaults to. Push it to 90% for hero images and product shots where detail is the point. 100% switches your browser's encoder into lossless mode, which is excellent for graphics and overkill for photos. **Are my images uploaded to a server?** No. The conversion runs inside your browser using the canvas your browser already ships with. Your file is read from your own device, converted in memory, and handed back to you. Nothing is transmitted, which means nothing can be stored, logged, or leaked. It also means the tool keeps working if your connection drops halfway through. **What is the maximum file size?** 4.0 MB per file. Above that, converting in the browser gets memory-hungry enough to crash the tab on a mid-range phone, so the tool declines the file rather than gambling with it. If your image is larger, compress or resize it first and then convert it here. **Can I choose the output quality?** Yes. The gear icon next to the Convert button opens the quality control, which starts at 75%. That is the setting where files stay small and the difference stays invisible on a photograph. Set it to 100% and your browser encodes WebP losslessly, which is what you want for logos, screenshots, and anything with text. **Is it really free?** Yes. No signup, no watermark, and no daily limit. Since the work happens on your device, converting an image costs us nothing to run, so there is nothing to charge you for. ### PNG to JPG Converter https://www.piknova.com/tools/png-to-jpg Converts PNG to JPG and flattens transparency onto a background colour, usually to make a screenshot small enough to send. **How do I convert PNG to JPG?** Drop your PNG file into the converter at the top of this page, or click the button to pick one. JPG is already selected as the output, so you can hit Convert straight away. When it finishes, the download button appears with the converted file. There is no queue, no email step, and no account. **What happens to transparent areas in my PNG?** They come out white. JPG has no alpha channel, so every converter has to put something behind the transparent pixels. We paint white underneath before encoding, because the alternative most tools fall back to is black, and a logo with a black halo is nobody's intention. If the transparency matters, PNG to WebP is the conversion you actually want. **How much smaller will the JPG be?** On a photograph, usually 80 to 95% smaller at the default 75% quality. On a screenshot full of text and flat color the saving is smaller and the artifacts are more visible, so bump the quality to 90 or 100 in the settings before converting. **Should screenshots be JPG or PNG?** PNG, if you have the choice. JPG compression works by smoothing away fine detail, and text is nothing but fine detail, so screenshots get fuzzy halos around letters. Convert a screenshot to JPG when something forces your hand on file size, and use 90% or higher when you do. **Are my images uploaded to a server?** No. The conversion runs inside your browser using the canvas your browser already ships with. Your file is read from your own device, converted in memory, and handed back to you. Nothing is transmitted, which means nothing can be stored, logged, or leaked. It also means the tool keeps working if your connection drops halfway through. **What is the maximum file size?** 4.0 MB per file. Above that, converting in the browser gets memory-hungry enough to crash the tab on a mid-range phone, so the tool declines the file rather than gambling with it. If your image is larger, compress or resize it first and then convert it here. **Can I choose the output quality?** Yes. The gear icon next to the Convert button opens the quality control, which starts at 75%. That is the setting where files stay small and the difference stays invisible on a photograph. 100% is the highest quality JPG offers. It is still a lossy format, so we will not pretend it is lossless. **Is it really free?** Yes. No signup, no watermark, and no daily limit. Since the work happens on your device, converting an image costs us nothing to run, so there is nothing to charge you for. ### PNG to WebP Converter https://www.piknova.com/tools/png-to-webp Converts PNG to WebP and keeps the alpha channel, for lighter web assets. **How do I convert PNG to WebP?** Drop your PNG file into the converter at the top of this page, or click the button to pick one. WebP is already selected as the output, so you can hit Convert straight away. When it finishes, the download button appears with the converted file. There is no queue, no email step, and no account. **Does WebP keep PNG transparency?** Yes. WebP has a full alpha channel in both its lossy and lossless modes, so transparent backgrounds convert across untouched. This is the main reason PNG to WebP is a better trade than PNG to JPG, which flattens transparency to white. **Is WebP lossless like PNG?** It can be. WebP has both modes. Set quality to 100% in the settings here and your browser encodes losslessly, giving you a pixel-perfect copy of the PNG in a file that is typically around 26% smaller. Anything below 100% is the lossy mode, which is fine for photos and unkind to sharp edges. **Are my images uploaded to a server?** No. The conversion runs inside your browser using the canvas your browser already ships with. Your file is read from your own device, converted in memory, and handed back to you. Nothing is transmitted, which means nothing can be stored, logged, or leaked. It also means the tool keeps working if your connection drops halfway through. **What is the maximum file size?** 4.0 MB per file. Above that, converting in the browser gets memory-hungry enough to crash the tab on a mid-range phone, so the tool declines the file rather than gambling with it. If your image is larger, compress or resize it first and then convert it here. **Can I choose the output quality?** Yes. The gear icon next to the Convert button opens the quality control, which starts at 75%. That is the setting where files stay small and the difference stays invisible on a photograph. Set it to 100% and your browser encodes WebP losslessly, which is what you want for logos, screenshots, and anything with text. **Is it really free?** Yes. No signup, no watermark, and no daily limit. Since the work happens on your device, converting an image costs us nothing to run, so there is nothing to charge you for. ### WebP to JPG Converter https://www.piknova.com/tools/webp-to-jpg Converts WebP to JPG for older software and upload forms that accept nothing but JPEG. **How do I convert WebP to JPG?** Drop your WebP file into the converter at the top of this page, or click the button to pick one. JPG is already selected as the output, so you can hit Convert straight away. When it finishes, the download button appears with the converted file. There is no queue, no email step, and no account. **Why will my computer not open a WebP file?** Because WebP is a web format, and desktop software adopted it slowly. Recent versions of Windows Photos and macOS Preview handle it fine, but older installs, many editors, and most print tools do not. Converting to JPG sidesteps the question entirely. **Will I lose quality converting WebP to JPG?** A little, and it depends on the setting. A lossy WebP has already been compressed once, so encoding it as a JPG compresses it a second time. At 90 or 100% quality the difference is genuinely hard to see. At 50% on a detailed image you will start to notice it. **Are my images uploaded to a server?** No. The conversion runs inside your browser using the canvas your browser already ships with. Your file is read from your own device, converted in memory, and handed back to you. Nothing is transmitted, which means nothing can be stored, logged, or leaked. It also means the tool keeps working if your connection drops halfway through. **What is the maximum file size?** 4.0 MB per file. Above that, converting in the browser gets memory-hungry enough to crash the tab on a mid-range phone, so the tool declines the file rather than gambling with it. If your image is larger, compress or resize it first and then convert it here. **Can I choose the output quality?** Yes. The gear icon next to the Convert button opens the quality control, which starts at 75%. That is the setting where files stay small and the difference stays invisible on a photograph. 100% is the highest quality JPG offers. It is still a lossy format, so we will not pretend it is lossless. **Is it really free?** Yes. No signup, no watermark, and no daily limit. Since the work happens on your device, converting an image costs us nothing to run, so there is nothing to charge you for. ### WebP to PNG Converter https://www.piknova.com/tools/webp-to-png Converts WebP to PNG, transparency intact, for software that still refuses to open a .webp file. **How do I convert WebP to PNG?** Drop your WebP file into the converter at the top of this page, or click the button to pick one. PNG is already selected as the output, so you can hit Convert straight away. When it finishes, the download button appears with the converted file. There is no queue, no email step, and no account. **Does WebP to PNG keep transparency?** Yes. Both formats have a full alpha channel, so transparent areas convert across exactly as they are. This is the main advantage over converting to JPG, which has no way to store transparency and fills it with white. **Why is the PNG larger than the WebP?** Because PNG stores every pixel exactly and WebP does not have to. If the original was lossy WebP, it got small by approximating; PNG has no such option, so it faithfully records the approximation at full cost. Expect a bigger file, and treat it as an editing copy rather than what you publish. **Can Photoshop open a WebP file?** Photoshop 23.2 and later open WebP natively. Anything older needs the WebPShop plugin installed by hand, which is the point most people give up and go looking for a converter instead. Converting to PNG first sidesteps all of it, and it is the better habit anyway: a PNG opens in Photoshop, Affinity, GIMP, Figma, Preview, Paint, and whatever your client is running, without anyone installing anything. **Does converting WebP to PNG improve the quality?** No, and it is worth being blunt about that because plenty of pages imply otherwise. PNG is lossless, so it preserves exactly what it receives. If the WebP was saved in lossy mode, the detail it threw away is already gone and no format can invent it back. What the conversion does buy you is that nothing degrades from here. Every future save is lossless, so you can edit, crop and re-save a dozen times without the slow smearing that repeated JPG or lossy WebP saves cause. **WebP to PNG or WebP to JPG, which one do I want?** Transparency decides it. If any part of the image is see-through, PNG is the only one of the two that can hold it; JPG has no alpha channel and will fill those areas with white. If the image is a photograph with no transparency and you care about file size, JPG is the more sensible target. PNG is the right answer for logos, screenshots, cutouts, icons, and anything with text or hard edges. **What happens to an animated WebP?** You get the first frame as a still PNG. PNG has no animation to convert into, and the browser hands the converter a single frame to draw, so the motion is not preserved. If you need the animation, keep the WebP or export a GIF from a video tool instead. **Can I convert several WebP files at once?** One at a time here. The converter takes a single file, which keeps it fast and keeps the memory footprint small enough to work on a phone. Converting a handful in a row is quick, since there is no upload or queue between them. **Are my images uploaded to a server?** No. The conversion runs inside your browser using the canvas your browser already ships with. Your file is read from your own device, converted in memory, and handed back to you. Nothing is transmitted, which means nothing can be stored, logged, or leaked. It also means the tool keeps working if your connection drops halfway through. **What is the maximum file size?** 4.0 MB per file. Above that, converting in the browser gets memory-hungry enough to crash the tab on a mid-range phone, so the tool declines the file rather than gambling with it. If your image is larger, compress or resize it first and then convert it here. **Can I choose the output quality?** Yes. The gear icon next to the Convert button opens the quality control, which starts at 75%. That is the setting where files stay small and the difference stays invisible on a photograph. PNG has no lossy mode, so the setting has nothing to do here and every export is pixel perfect. **Is it really free?** Yes. No signup, no watermark, and no daily limit. Since the work happens on your device, converting an image costs us nothing to run, so there is nothing to charge you for. ## YouTube downloaders ### YouTube Thumbnail Downloader https://www.piknova.com/tools/youtube-thumbnail-downloader Paste a video link and download its thumbnail at full resolution, up to 1280x720, with the smaller sizes listed too. **What is a YouTube thumbnail downloader?** It's a tool that saves the preview image of any public YouTube video, Short, or livestream directly to your device, without downloading the video itself. Paste a link and the tool reads the video ID, then pulls the same thumbnail files YouTube already hosts publicly. No screenshots, no guesswork. **What resolutions can I download?** Every size YouTube generates for a video is available here: Max HD (1280 x 720): Only exists if the creator uploaded a custom thumbnail.. Standard Definition (640 x 480): Available for almost every video.. Medium Resolution (480 x 360): A compact thumbnail size for previews and embeds.. Low Resolution (320 x 180): Smaller file size, faster to save. The download is the full image exactly as uploaded. There's no separate background layer to isolate, since a thumbnail is a single flat image. **Is this YouTube thumbnail downloader really free?** Yes, free forever. No account, no credits, no daily cap, and no watermark stamped on the image at the download step. The thumbnail comes from YouTube's own image servers straight to your browser, so this costs us close to nothing to run. That's why there's no catch to explain. **Does this work for YouTube Shorts?** Yes. Paste any youtube.com/shorts/ link and it's handled exactly like a regular video, with every available resolution pulled and ready to download. Those are the landscape versions. For the vertical 9:16 cover the Shorts feed shows, use the YouTube Shorts Thumbnail Downloader. **Can I download a live stream's thumbnail?** Yes, for scheduled, active, and ended live streams. An active stream's thumbnail can be an auto-generated frame that changes as the broadcast continues, so what you download reflects that moment. **How do I download a thumbnail from a YouTube link?** Three steps, no installs: Copy the link: From YouTube's share button or your browser's address bar.. Paste it above: Any video, Shorts, or Live URL format works.. Pick a size: Each resolution has its own Download button. Save one or all of them. **Can I download thumbnails from several videos at once?** One video at a time. Save the sizes you want from the link you pasted, then paste the next link and repeat. Bulk pulling a whole channel is what gets tools rate limited by YouTube, and a downloader that stops working for everyone isn't much of a downloader. **Do I need a Chrome extension to download YouTube thumbnails?** No. A browser extension has to be installed and granted permissions, and it only runs on desktop Chrome, so it won't help you on mobile Chrome or any other browser. This tool works the same on any device with a browser, with nothing to install and nothing to uninstall later. **Can I reuse a downloaded YouTube thumbnail?** A thumbnail is created by the video's channel and is protected the same way any image is. Downloading one for personal reference, archiving, or commentary is generally fine. Republishing it as your own or using it commercially without permission can raise copyright issues. This isn't legal advice, so when in doubt, ask the channel or credit the source. **Why doesn't the HD thumbnail show for some videos?** Only videos where the creator uploaded a custom high-resolution thumbnail have a true 1280 x 720 version. Older or auto-generated thumbnails often only exist at a smaller size. When Max HD isn't available, the tool detects this automatically and shows the next-best resolution instead of a broken image. **Can I download a YouTube thumbnail in 4K?** No. YouTube thumbnails max out at 1280 x 720 (Max HD), regardless of the resolution the video itself was uploaded in. That's the largest thumbnail YouTube generates, and it's what this tool downloads when it's available. ### YouTube PFP Downloader https://www.piknova.com/tools/youtube-pfp-downloader Downloads a YouTube channel's profile picture at full size from a channel URL or any of its video links. **How do I download someone's YouTube profile picture?** Three steps, nothing to install: Copy the link: The channel URL, any video from that channel, or their @handle.. Paste it above: Press Get Profile Picture and the channel's avatar appears.. Pick a size: Original for the real thing, or one of the six presets. **What is a PFP, and is it the same as a DP or an avatar?** PFP is short for profile picture. DP (display picture), avatar, channel icon, channel logo and profile photo all describe the same square image on a YouTube channel. So a YouTube DP downloader, a YouTube avatar downloader and a YouTube PFP downloader are the same tool wearing different words. This one is all of them. **Can I download a YouTube profile picture in 1280x1280 or 4K?** Sometimes yes, and sometimes the original is far bigger than that. Channel pictures are stored at whatever size the creator uploaded, which ranges from about 125 pixels to several thousand, and Google's image server renders any size you ask for on top of that by interpolating. So a fixed HD number is the render, not the source, which is how every tool in this category can advertise the same one for every channel. Ask for 1280 on a channel storing 125 px and you get a blurry 1280. Ask for it on a channel storing 6000 px and you have thrown away most of the picture. This tool shows you the real number and marks the rest as upscaled. **Why is the original not a perfect square?** YouTube crops avatars to a square for display, but it keeps the file the creator uploaded. If they uploaded something slightly off-square, Original hands back those exact dimensions, like 500 x 499. If you need a guaranteed square, use one of the presets. Those are the cropped renders YouTube serves on its own pages. **Does this work for any channel?** Any public channel. If a channel has been terminated, made private, or never set a custom picture, there's nothing public to fetch and the tool will say so instead of showing a broken image. **Do I need to sign in or install an extension?** No to both. A browser extension only runs on desktop Chrome and has to be granted permissions; this page works in any browser on any device, including a phone. **Can I use a YouTube profile picture I downloaded?** A channel's picture belongs to whoever made it, and a logo can be a trademark on top of that. Saving one for reference, commentary, a review or a mockup is generally fine. Passing it off as your own brand, or implying a channel endorses something, is where it stops being fine. This isn't legal advice, so when it matters, ask the channel. **Can I download a channel's banner too?** Not with this tool. The banner is the wide artwork across the top of a channel page, which is a separate image rather than another size of the profile picture. This tool does the square one. ### YouTube Banner Downloader https://www.piknova.com/tools/youtube-banner-downloader Downloads a YouTube channel's banner, also called channel art, at full resolution. **How do I download a YouTube channel's banner?** Three steps, nothing to install: Copy the link: The channel URL, any video from that channel, or their @handle.. Paste it above: Press Get Banner and the channel's artwork appears.. Pick a version: Full channel art for the whole picture, or Only the part YouTube shows for the thin slice on a channel page. **Why is the banner I downloaded elsewhere so short and wide?** Because you got the crop, not the picture. YouTube displays a strip roughly 2560 x 423 out of the middle of a 2560 x 1440 upload, and that cropped URL is what sits in the channel page's source, so it is what most tools copy. The crop is a parameter on the image URL. This tool removes it, which is why the full channel art option here is about three times taller than the same banner from anywhere else. **Is a banner the same as channel art, a cover photo or a header?** Yes. Channel art is YouTube's official term, banner is what most people say, and cover photo, channel header and channel cover all describe the same image. So a YouTube channel art downloader, a cover photo downloader and a banner grabber are the same tool wearing different words. This one is all of them. **What size is a YouTube banner?** YouTube asks for 2560 x 1440 on upload. The safe area that shows on every device is the middle 1546 x 423, which is where a logo or any text has to sit if you don't want it cropped on a phone. That said, uploads are not capped at 2560. This tool reports the real dimensions of whatever the channel you pasted actually uploaded, and we have seen anything from 2048 to 4096 wide. **Can I download a banner in HD or 4K?** You get whatever the creator uploaded, which for a 3840 x 2160 upload genuinely is 4K. If they uploaded 2048 wide, no tool can conjure a 4K version; asking Google for a bigger render just interpolates pixels. That's why any width larger than the original gets a Stretched tag here instead of being sold as HD. **Why does this say the channel has no banner?** Setting channel art is optional, and plenty of smaller or newer channels never do. If there is no banner on the channel, there is no file to download, so the tool says so rather than showing a broken image. **Do I need to sign in or install an extension?** No to both. A browser extension only runs on desktop Chrome and has to be granted permissions; this page works in any browser on any device, including a phone. **Can I use a banner I downloaded?** Channel art belongs to whoever made it, and it often carries a logo that is a trademark on top of that. Saving one for reference, study, commentary or a mockup is generally fine. Putting it on your own channel, or using it in a way that suggests the creator endorses something, is where it stops being fine. This isn't legal advice, so when it matters, ask the channel. ### YouTube Shorts Thumbnail Downloader https://www.piknova.com/tools/youtube-shorts-thumbnail-downloader Paste a Shorts link and download its vertical 9:16 thumbnail (1080x1920 or 720x1280, depending on the Short) and the landscape sizes YouTube has, each labelled with the dimensions measured from the file. It cannot produce a size YouTube did not generate, and it does not work for private or deleted Shorts. **How do I download a YouTube Shorts thumbnail?** Three steps, nothing to install: Copy the link: Tap Share on the Short and Copy link, or copy it from the address bar.. Paste it above: Press Get Shorts Thumbnail and the cover appears with its real size.. Save a size: The top row is the biggest vertical cover YouTube has for that Short. **Is this Shorts thumbnail downloader free?** Yes. No account, no daily limit, no watermark, and every size is free to save. **Do I need an app or a browser extension?** No. It is a web page, so it works in any browser on a phone, a tablet or a computer. Extensions only run on desktop and want permissions to every site you visit; this needs none. **How do I save a Shorts thumbnail on an iPhone?** Open this page in Safari, paste the link and press Save. The file lands in the Files app under Downloads. To put it in Photos instead, press and hold the preview image and choose Save to Photos. **How do I save a Shorts thumbnail on Android?** Open this page in Chrome, paste the link and press Save. The image goes to your Downloads folder, which shows up in most gallery apps as a Downloads album. **What size is a YouTube Shorts thumbnail?** The vertical cover is 9:16. On most Shorts we measured it was 1080 x 1920, and on some it stopped at 720 x 1280. The landscape versions are 1280 x 720 at most. It varies by Short, which is why the tool measures the one you paste instead of quoting a number. **Can I download a Shorts thumbnail in HD or 4K?** HD, yes: a 1080 x 1920 cover is full HD turned on its side. 4K, no. YouTube does not keep a Shorts thumbnail bigger than 1080 x 1920, so a site promising 4K is either upscaling a smaller file or labelling it wrong. The size printed on every row here is measured from the file itself. **Why did my Shorts thumbnail come out 16:9?** You saved a landscape version. YouTube makes those for search results and the regular player, and most thumbnail tools only know about them. The vertical cover is a separate file, and here it is the row marked 9:16 at the top of the list. **Why is the thumbnail blurry or low quality?** Usually because a small size was saved. Take the top row, which is the largest image YouTube has for that Short. If that is 720 x 1280, nothing bigger exists, and enlarging it will not add detail. **Why are the sizes different for every Short?** YouTube does not make every file for every Short, and the vertical cover is not always made at the same size. Two Shorts from the same channel can come back with different lists, and that is what YouTube actually has, not a glitch. **Which Shorts links work?** youtube.com/shorts links, mobile m.youtube.com links, the share link from the app (the ?si= part is ignored), youtu.be links, watch links, and the bare 11 character video ID. The https:// is optional. **Why does it say there is no thumbnail?** The Short is private, deleted, or was uploaded moments ago and is still processing. In the first two cases YouTube stops serving its images, so no tool can get them. In the last, try again in a few minutes. **Does it work for unlisted Shorts?** Usually, yes. An unlisted Short is hidden from search but its images are served like any other, so if you have the link, the thumbnail comes through. **Is there a watermark on the download?** No. You get YouTube's own JPG, byte for byte, with nothing added and nothing re-compressed. **Do you store the link or the image?** No. The image goes from YouTube to your device without passing through our servers. Our analytics counts that a lookup happened and which size was saved, never the link. **Can I use a Shorts thumbnail commercially?** The thumbnail belongs to the creator who made it. Saving one for reference, study, commentary or a mock-up is generally fine; reusing it on your own channel, in an ad, or anywhere that suggests the creator endorses you is not. This isn't legal advice, so when it matters, ask the creator. **Does this download the Short itself?** No, only its thumbnail images. The video stays on YouTube. **How do I make the thumbnail 1080 x 1920, or another size?** If the cover is already 1080 x 1920, you are done. For anything else, like a 720 x 1280 cover or a size for Reels or TikTok, save it here and open it in Exact Size Crop or Crop Image to 9:16. Going down in size looks clean; going up only adds blur. ## Pages with a preset - [Compress Image to 15KB](https://www.piknova.com/tools/compress-image-to-15kb): Opens the compressor with a 15 KB target already set. - [Compress Image to 20KB](https://www.piknova.com/tools/compress-image-to-20kb): Opens the compressor with a 20 KB target already set. - [Compress Image to 25KB](https://www.piknova.com/tools/compress-image-to-25kb): Opens the compressor with a 25 KB target already set. - [Compress Image to 30KB](https://www.piknova.com/tools/compress-image-to-30kb): Opens the compressor with a 30 KB target already set. - [Compress Image to 50KB](https://www.piknova.com/tools/compress-image-to-50kb): Opens the compressor with a 50 KB target already set. - [Compress Image to 60KB](https://www.piknova.com/tools/compress-image-to-60kb): Opens the compressor with a 60 KB target already set. - [Compress Image to 90KB](https://www.piknova.com/tools/compress-image-to-90kb): Opens the compressor with a 90 KB target already set. - [Compress Image to 100KB](https://www.piknova.com/tools/compress-image-to-100kb): Opens the compressor with a 100 KB target already set. - [Compress JPG to 100KB](https://www.piknova.com/tools/compress-jpg-to-100kb): Opens the compressor with a 100 KB target already set, on a page written for JPEG files. - [Compress Image to 200KB](https://www.piknova.com/tools/compress-image-to-200kb): Opens the compressor with a 200 KB target already set. - [Compress Image to 500KB](https://www.piknova.com/tools/compress-image-to-500kb): Opens the compressor with a 500 KB target already set. - [Compress Image Without Losing Quality](https://www.piknova.com/tools/compress-image-without-losing-quality): Opens the compressor on its gentlest setting, for shrinking a file with no visible change. - [Exact Size Crop](https://www.piknova.com/tools/exact-size-crop): Opens the crop frame with the width field focused, for typing an exact pixel size.
