I mean, they could have used APNG at this point. https://caniuse.com/apng https://caniuse.com/apng Doesn't compress stuff like that super well but no worse than a sequence of PNGs. I feel if you're gonna use JS animation anyway, you could just use 2 jpegs, one for masking and a canvas. Hm. Webp is doing darn well these days too. https://caniuse.com/webp https://caniuse.com/webp Avif isn't an option yet.
