Right now you can only select webp and avif but gif and png are available when you change the url so a button would be nice.
#Add buttons to preview more formats

apng is banned (too big), so png would be static (yuck)
gif is yucky too, but at least would work
overall I don't think this feature is needed. Making gif downloads this easy would encourage people to use those versions to make emote variants, which will end up looking more horrible with every iteration. I think most emote artists are savvy enough to take a webp or avif and convert it to an editable format, if their software of choice doesn't support them. But the more ideal end goal would be putting pressure on image editing software to support webp or avif natively. (very pagman)
