Convert PNG images to JPG. Usually a large drop in file size — and you choose what colour fills the transparent parts.

The reason is usually size
PNG stores every pixel exactly, which is the right choice for a logo and the wrong one for a photograph. A screenshot of a photo saved as PNG can easily be five or ten times the size of the same picture as a JPG, and that is what makes upload forms reject it and email attachments bounce.
Converting to JPG lets the encoder discard the detail nobody can see, and the saving on photographic content is dramatic. On flat graphics — a screenshot of a spreadsheet, a chart with thin lines — the saving is smaller and the damage is more visible, so those are better left as PNG.
The transparent part has to become something
JPEG has no alpha channel, so a transparent background cannot survive the conversion — it has to be painted. White is the default because it is what most documents and most upload forms sit on.
White is not always right, though. A logo destined for a dark slide will arrive with a white box around it, which looks worse than not converting at all. So the colour is yours to pick: set it before or after dropping the files, and every result is rebuilt with the new colour straight away.
When to keep the PNG instead
Anything that needs its transparent background — logos, stickers, UI assets, product cut-outs. Once it is a JPG the background is painted on permanently and no tool can take it off again.
Also anything that is mostly flat colour and sharp edges. JPG compresses by smoothing, and smoothing is exactly wrong next to a hard black line on white; the letters in a screenshot pick up a visible haze. If you only wanted the file smaller and the picture is that kind of image, the compress tool on this site will keep it as a PNG.

- Drop your .png files onto the box above, or click it to browse.
- If the images have transparent areas, choose the colour to fill them with.
- Download each JPG, or take the whole batch as one ZIP.
Usable on a work computer
Plenty of workplaces block file uploads to outside websites, to keep contracts and customer records from leaving the building. On those machines the usual online converters simply fail.
This one has no upload to block. Whether your organisation permits a particular site is still its own call, so check with your IT team if you handle regulated material.
Why this is built this way
Files that pass through someone else's server can be logged, cached, retained after the promised deletion window, or exposed in a breach. Contracts, ID scans, medical records and private photos are exactly the files people most often have to convert, and exactly the ones that should not be handed to a stranger's machine.
It is also why there is no file size limit, no daily quota, and no account. Those restrictions exist to control server costs. With no server in the loop, there is nothing to ration.
Questions about PNG to JPG
Are my images uploaded anywhere?
No. The picture is decoded and re-encoded by your own browser, and no request leaves the page while it works. You can confirm it: open the browser's developer tools, switch to the Network tab, and process a file — the only requests are for this page's own script files, and none of them carry your image.
How much smaller will the file be?
For a photograph saved as PNG, typically 80–90 percent smaller. For a flat graphic — a screenshot of text, a simple chart — often much less, and sometimes larger, because JPG is not built for hard edges. The result card shows both sizes so you can see what actually happened.
Can I get the transparency back afterwards?
No. The fill colour becomes ordinary pixels in the JPG, indistinguishable from any other part of the picture. Keep the original PNG if there is any chance you will need the transparent version again.
Why does my screenshot look fuzzy around the text?
That is JPG doing what JPG does: it compresses by smoothing, and smoothing next to a hard edge produces a faint halo. Text and line art are exactly the worst case for it. For those images, keep the PNG and use the compress tool if size is the problem.
Does the photo keep its shot date and location?
No. The result is re-encoded from the pixels, so EXIF metadata — the shot date, camera model and GPS location — is not carried over. The rotation is applied to the pixels first, so the picture stays the right way up. If you need the shot date preserved, use the HEIC to JPG converter on this site instead: keeping EXIF is what that tool is for.
