It's a .webp file for me.
Chances are the program you're using supports all this crap, and ignores the extension anyway, because far too many people just rename files to "convert" them.
Only real way to be sure is to open it with a hex editor. The first few bytes will tell you what a file type really is.
Lemmy probably returns images in different formats depending on what client supports (and ones with better compression take precedence).
