So animated GIFs can be replaced by Animated PNGs with alpha blending with transparent backgrounds and lossless compression! Some nostalgia from 2000s websites can be revived and relived :)

Curious if Animated SVGs are also a thing. I remember seeing some Javascript based SVG animations (it was a animated chatbot avatar) - but not sure if there is any standard framework.

When it comes to converting small video snippets to animated graphics, I think WEBP was much better than APNG from the beginning. Only if you use GIF as intermediate format then APNG was competitive.

Nowadays, AVIF serves that purpose best I think.

webm or any other non-gimped video codec would be a much better format for that use case. Unfortunately browsers don't allow those in image contexts so we are stuck with an inferior "state of the art" literally-webm-with-deliberately-worse-compression webp standard.

AVIF is only starting to become widespread so can't be used without fallback if you care about your users. Not sure how it compares to AV1 quality/compression wise but hopefully its not as gimped as webp and there will encoders that aren't as crap as libwebp that almost everyone uses.
