The short version

Why convert PNG to JPG?

This one is almost always about size. A PNG is lossless, and lossless is expensive.

A full screen grab on a modern display can leave you with a 6 MB PNG. The same image as a JPG at 75% quality is frequently under 400 KB and looks the same at a glance, which is the difference between an attachment that sends and one that bounces.

  • Attachment and upload limits: Job portals, forms, and older email setups routinely cap uploads at 2 MB or reject PNG entirely.
  • Photos that were saved wrong: If a phone or an app handed you a photograph as a PNG, it is wasting megabytes for nothing. JPG is the format that photo should have been in.
  • Anywhere you are paying for bandwidth: Email campaigns, marketplace listings, and bulk product images all get cheaper and faster in JPG.

Worth knowing: JPG cannot store transparency. Any transparent area in your PNG comes out as solid white here, which is the sane default and prevents the black boxes that some converters produce. If you need the transparency, convert to WebP instead, which keeps it and still saves you most of the size.

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.

Joint Photographic Experts Group

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.

Everything the PNG to JPG 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 PNG becomes a JPG 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.

No black boxes

JPG cannot store transparency, so we paint white behind it first. That is the result you expected, not the dark rectangle other converters hand you.

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.

PNG to JPG: common questions

What people ask before converting PNG files 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.

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.

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.

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.

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.

100% is the highest quality JPG offers. It is still a lossy format, so we will not pretend it is lossless.

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.
