Convert PNG to JPG
The usual reason to go from PNG to JPG is size: JPG throws away detail the eye barely notices and keeps the rest, which is a good trade for a photograph and a bad one for anything with hard edges or a transparent background.
Add a PNG here and it converts straight to JPG — this page already has that output selected. Expect a 75–85% smaller file for a photograph, and know before you start that any transparent area becomes solid, because JPG cannot store an alpha channel at all. Nothing is uploaded.

What you lose, specifically
Transparency is the one that surprises people. JPG has no alpha channel, so a transparent area is filled with a solid colour on the way out — usually white — and there is no getting it back afterwards. If the image needs to stay transparent, this is the wrong conversion; PNG to WebP keeps it and still saves space.
The compression itself is lossy, which matters most on hard edges. Screenshots and anything containing text develop visible fringing around letters at low quality settings; photographs mostly hide it.
- Check for transparency first — if the PNG has any, decide whether losing it is acceptable
- Raise the quality setting above 90 for anything with text or fine lines
- Photographs shrink the most; flat graphics shrink the least and sometimes grow
Nothing is uploaded to convert it
The conversion runs on your own device. Your image is decoded and re-encoded in the browser tab and the result is written back — no copy of it, at any stage, is ever sent anywhere.
You can confirm it: open the Network tab before you start, or disconnect from the internet once the page has loaded and convert anyway. The only thing that needs a connection is the first load of the page itself.
Questions
- Will my transparent background survive?
- No. JPG cannot store transparency in any form, so a transparent area becomes a solid colour — usually white — in the converted file, and that cannot be undone afterwards. Convert to WebP instead if transparency matters.
- How much smaller will the file be?
- For a photograph, typically 75–85% smaller than the original PNG at a reasonable quality setting. Flat graphics with few colours save far less, because PNG already compresses that kind of image well.
- Is this lossy?
- Yes. Some detail is discarded to reach the smaller size. At the default quality it's very hard to see on a photograph; at low quality it shows up as blotchiness in flat areas and fringing around text.
- Is my image uploaded to convert it?
- No. The whole conversion runs in your browser — confirm it in the Network tab, or disconnect after the page loads and it still works.
- Can I convert several PNGs to JPG at once?
- Yes, with no limit on how many. Each is processed on your device and appears with its own download as soon as it's done.
