there are appropriate uses for each, but 99.9% of people don't know or care what to use, and lots of sites will indiscriminately convert things which further reduces quality. and then there's people on phones who just take screenshots of a meme because they're on a phone and they either can't be bothered with trying to save the original file, or the site intentionally obfuscates it in such a way as to prevent direct saving, which then results in wasted space. the modern internet is an absolute clusterfuck
