The short version
Why convert JPG to PNG?
Almost everyone doing this is solving one of three problems, and it is worth knowing which one is yours.
- Something on the other end demands PNG: App icon uploaders, custom emoji, print portals, and plenty of internal tools accept a PNG and reject everything else. This is the most common reason by a wide margin.
- You are about to edit it repeatedly: Every JPG save re-compresses the whole image. Converting to PNG first freezes the current state, so ten rounds of edits cost you nothing more in quality.
- You need a transparent background: JPG has no alpha channel at all. Converting to PNG gives your editor somewhere to put the transparency once you cut the background out.
Worth knowing: Converting to PNG does not undo what JPG already discarded. It preserves the image exactly as it is now, artifacts included. Expect the file to grow too: a photo that is 800 KB as a JPG often lands between 3 and 5 MB as a PNG, because photographic noise is the hardest thing there is to compress losslessly.

What is a JPG?
JPG is the format your camera, your phone, and most of the internet reach for when the picture is a photograph. It throws away detail your eye is bad at noticing and keeps the file small in return.
That trade is the whole point. A 12 megapixel photo would be roughly 36 MB with nothing thrown away. As a JPG it lands somewhere near 3 MB and still looks like the photo you took, which is why it has survived since 1992 while flashier formats came and went.
The catch is that the throwing away happens every single time you save. Edit a JPG, save, edit again, save again, and you are compressing an already compressed image. It shows up first as blocky halos around hard edges and text, which is also why JPG is a poor home for screenshots, logos, and anything with flat color.
JPG also has no transparency. There is no alpha channel in the format at all, so a transparent background becomes a solid one the moment you save.
Best for: Photographs, camera output, and anything headed for an upload form with a size limit.

What is a PNG?
PNG is the lossless one. What goes in comes back out pixel for pixel, however many times you open and re-save it, and it carries real transparency.
It was built in 1996 as a patent-free answer to GIF, and it inherited GIF's best trick while fixing its worst limit: PNG supports a full 8-bit alpha channel, so a logo can sit on any background with soft, properly anti-aliased edges instead of a jagged cutout.
Because nothing is discarded, PNG is the safe container for images made of flat color and hard edges: screenshots, UI mockups, charts, diagrams, line art, and any graphic with text in it. Those are exactly the images JPG mangles.
The price is size. On a detailed photograph a PNG can easily be five to ten times larger than the equivalent JPG, because photographic noise is the worst possible input for lossless compression.
Best for: Screenshots, logos, diagrams, anything with text, and any image that needs a transparent background.
Other JPG and PNG converters
Same tool, same privacy, different formats. Pick the conversion you need next.
Everything the JPG to PNG conversion needs, nothing it does not.
One file, two dropdowns, one button. The rest is your browser doing the work.
Converts in a blink
Your browser decodes and re-encodes the file locally, so a JPG becomes a PNG in about as long as it takes to read this.
Never leaves your device
No upload, no server, no copy of your image sitting in someone's bucket. Close the tab and it is gone.
You pick the quality
Default is 75%, which keeps files small. Push it to 100% when the detail matters more than the size.
Room for transparency
JPG has no alpha channel and PNG does, so once it is converted you can cut out the background and it will stay cut out.
No install, no signup
It is a web page. Nothing to download, no account to make, no watermark on the way out.
Works on your phone
Same tool, same speed on mobile. Convert a screenshot on the train and download it straight to your camera roll.
JPG to PNG: common questions
What people ask before converting JPG files 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.
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.
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.
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.
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.
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.
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.
Yes. No signup, no watermark, no daily limit, and no ads on the page. Since the work happens on your device, converting an image costs us nothing to run, so there is nothing to charge you for.
