I don’t know what a .webp file is but I don’t like it. They’re like a filthy prank version of the image/gif you’re looking for. They make you jump through all these hoops to find the original versions of the files that you can actually do anything with.
Edit: honestly I assumed it had something to do with Google protecting themselves from image piracy shit
As opposed to what widely supported animated image format?
APNG, WebP, AVIF, WebM. Not sure about JpegXL
GIF is size and ressource heavy
