> Animated PNG is supported in every single modern browser, and degrades gracefully (the first frame is at least rendered.)

That’s part graceful and part a security hole. It means you can hide any image you want if moderation tools don’t show past the first frame.

One interesting aspect of WebP support (or lack thereof) is that it doesn't work in Slack or Discord, even when those are running in a supported browser. I think things like this are inhibiting adoption of newer formats.

That is a way better solution, although APNG didn't help much for my test in terms of data, a 1.8mb gif was converted to a 1.5mb apng, not even worth my time to google gif to apng converter.

Webp worked well though, resulting in a 300kb webp. Might try to start using it

edit: nevermind, webp doesn't work on whatsapp.
