Almost everyone doing this conversion has hit the same wall: an image saved from the web is a WebP, and something downstream will not take it — an older photo editor, a print service, a job application upload, a device gallery.
JPG is the safest thing to hand such a system. The cost is another round of lossy compression on an already lossy file, and the loss of any transparency the WebP carried.

How it works
- Choose the WebP files that will not open.
- Set the quality; keep it high to limit a second round of loss.
- Convert and download the JPG files.
Frequently asked questions
Why will nothing open my WebP file?
Browsers support WebP broadly, but plenty of desktop software, print services, and upload forms still do not. That gap is the usual reason for this conversion.
Does converting lose quality?
Some. A lossy WebP is decoded and then compressed again as JPG, and each lossy pass costs a little. Choosing a high quality setting keeps it small enough to be hard to see.
What happens to a transparent WebP?
The transparency is filled with white, because JPG cannot store it. Convert to PNG instead if you need to keep it.
