The file usually gets much smaller, and any transparent areas are filled with white because JPEG cannot store transparency. Nothing is uploaded, no account is needed, and the width and height stay the same.
Why make this conversion?
A photograph saved as PNG is often several times the size of the same picture as a JPEG, which is why upload forms, email attachments and web pages usually want JPEG.
Screenshots and logos are the exception: those stay sharper, and often smaller, as PNG.
How much does the file size change?
We saved the same seven images, five photographs and two graphics, as PNG and as JPEG with this converter, at its default quality of 82. Only the format changed.
PNG has no quality setting: it keeps every pixel, which is why its files are so large.
| Image | PNG (KB) | JPEG (KB) | Change |
|---|---|---|---|
| Waterfall in forest | 12,754 | 1,168 | -91% |
| Cityscape with signage | 21,421 | 1,755 | -92% |
| Sunflower, blurred background | 7,588 | 453 | -94% |
| Mountain range and sky | 10,177 | 709 | -93% |
| Waterfall, close crop | 2,699 | 341 | -87% |
| Screenshot of a web page | 131 | 69 | -48% |
| Share card with text | 109 | 43 | -61% |
On the five photographs, JPEG came out 87 to 94 percent smaller than PNG.
How close each format stayed to the original is in JPG vs PNG vs WebP vs AVIF, measured.
A conversion never improves a picture
Changing the format changes how the pixels are stored, not what they show. Detail an earlier save discarded is gone, and no later format can work out what used to be there.
If the original file still exists, convert from that instead.
Where it does matter is the order of the work. Resize and crop first, convert last.
Every save to a lossy format costs a little quality, so the fewer round trips a file makes, the better it looks when you are finished.
What happens to your photo?
Your selected photo is processed in your browser, without an image upload to a server. The page may download code and codecs needed for editing.
Save your result before closing the tab; unsaved edits are kept in memory rather than in an online account.
Common questions
What happens to a transparent background?
It is filled with white before the JPEG is written, because the format has no way to record transparency.
If that area mattered, keep the PNG as well: once it has been flattened there is no way to recover it from the JPEG.
Will the picture look worse as a JPG?
On a photograph, at the default quality, the difference is hard to see.
On a screenshot, a logo or anything with hard edges and flat colour it is obvious: JPEG smears a sharp edge into a faint halo.
Those are the images to leave as PNG.
