Change a PNG to JPG

To change PNG to JPG, select or drop your PNG on this page, keep Balanced or pick another Image quality, and press Convert to JPEG. The JPG is made in your browser, so nothing is uploaded, and it keeps the name of the PNG: holiday.png is saved as holiday.jpg.

A PNG stores every pixel exactly. That keeps screenshots and logos crisp, but it makes photos heavy. JPEG compresses the picture: it leaves out fine detail your eye is unlikely to miss. We tested this PNG to JPG converter with a photo of 2400 × 1600 pixels. As a PNG it was 6.2 MB; as a JPG at Balanced it was 622 KB, about a tenth of the size, with the same number of pixels.

That loss is why the route is graded Very good rather than Exact: some fine detail is gone, but a photo looks right at normal size. For how JPEG chooses what to leave out, read our guide to lossy vs lossless compression.

A JPG has no see-through pixels, so the converter puts a white background behind the picture before it saves. A logo on a transparent background comes out on a white rectangle. A half see-through shadow or edge is blended with that white, so it looks paler than before.

A logo is also where JPG saves nothing: our 2.9 KB transparent PNG logo came out at 11.9 KB as a JPG. To keep the background see-through, keep the PNG, or convert PNG to WebP, which keeps transparent areas. For a logo that must stay sharp at any size, PNG to SVG traces it into vector shapes.

Image quality has three settings, and each one trades file size against detail. These are the sizes our 6.2 MB test photo came out at in Chrome:

Each browser has its own JPEG encoder, so the sizes differ a little: in Firefox the same photo came to 630 KB at Balanced. For a high quality JPG, choose Best. No setting keeps every pixel, though, so a picture that must stay exact should stay a PNG.

Sharp letters, thin lines and flat colour are where JPEG does worst, and a screenshot is made of them. It often gets no smaller either. A 2560 × 1600 screenshot of a settings screen, 114 KB as a PNG, came out at 122 KB as a JPG at Balanced in Chrome, and at 156 KB in Firefox. Convert a screenshot only when a form or app takes nothing but JPG, or try the PNG converter, which shows the size a picture would come to in each format before you pick one. For the rule of thumb in full, read when to send a JPEG and when to send a PNG.

Whatever the picture, the JPG has the same width and height in pixels as the PNG, and a colour profile such as Adobe RGB comes with it, so colours do not shift. Camera and location details are not carried over, so a photo shared as the JPG does not say where it was taken.

There is nothing to install. The converter runs in current Chrome, Edge and Firefox, so the steps are the same on a Mac and on a Windows PC, and it is free with no daily limit.

To batch convert PNG to JPG, add up to 100 PNGs at a time. They convert one after another on your device, each JPG named after its PNG. Save each one with its own Download button, or press Download all (ZIP) to get them together in whatafile-converted.zip.

Other pictures have pages of their own: convert WebP to JPG, convert SVG to JPG or convert GIF to JPG. Going back the other way, convert JPG to PNG gives a lossless copy, but the detail the JPG left out does not return.
