@realcaseyrollins @mia @lucy @realcaseyrollins nothing. it's just 20+ years old.

pretty much the whole industry wanted jxl because you can repack existing jpegs, with no loss of quality, and save maybe 5%, which amounts to a lot when you are facebook and are pushing millions of images. plus it handles lossless, so you can repack the pngs too, smaller, and open both with just one decoder. it's totally better.
