Why are 90% of the images WebP format? (lemmy.world)

is it a formatting step that an image goes through when uploaded? I'm tired of converting image after image back into jpg, so if there's like a step I can take to avoid it being a webp, it would help to know

I don't see a reason to convert to jpg even for photos. Its advantages are related to the way compression artifacts looked more natural than the compression artifacts of contemporary formats. Why save as a format that's prone to obvious compression artifacts at all anymore?

Depends if you are aiming for best quality for a given file size, or if you don't care how big the file is.

Jpg has some advantages with photos, because it takes advantage of pixel fuzzing which isn’t visually noticeable in photos and can contribute greatly to higher compression.
It’s objectively terrible for everything else, though (because of the pixel fuzzing).
