I've never experienced this behavior, but I see people do mention it online. I also just tried to save a JPEG image, and Chrome offered to save it as JPEG. Could it be that the web page offered different formats and Chrome chose WebP? Developers can do this now: <picture> <source srcset="some-image.webp" type="image/webp"> <source srcset="some-image.jpg" type="image/jpeg"> <img src="some-image.jpg" alt="..."> </picture> If Chrome chose to display the WebP image, that's what it will offer to save even if the <img> tag points to the JPEG version.
