As demonstrated here by the most recent image uploaded to Community Central, which serves a webp instead of jpg for Chrome, Firefox, Opera - and Chrome on Android. Please name a browser it doesn't serve a webp for, or stop claiming it only effects "specific browser versions" without evidence. Vivaldi 2.6.1566.49 downloads the jpg (or at least file extension says so), as well as an outdated version of Firefox (didn't check the exact number, though). The updated Firefox 73.0.1 downloads the same file with the webp extension. All of the three downloaded files have the exact same file size, so all of them might actually be webp, and the two jpgs are incorrect extensions or vice versa.

Nevertheless, MS Paint (Windows 10) did not have any issue opening them. The test wiki accepted the two "jpg" files without any issue, the webp was accepted after I replaced the file extension on my computer. No resaving in image editor was necessary.

Intriguing, the browser version does seem to have influence, but there seems to be another puzzle piece missing.
