Note that the decoder is 68K compressed. That's not much, and of course can be cached, but considering that the improvement (from WebP, anyway) seems to be most notable for the <50K images, it may not be terribly practical... Considering that the page says it's based on a Daala comparison page, it would be interesting to stick a Daala snapshot in the mix for comparison using the same images (reencoding to PNG like it does for WebP, I'm not suggesting porting Daala to emscripten). A quick browse of the original page shows Daala sometimes beating x265, sometimes losing to it, but I guess both x265 and the Daala {encoder, codec} may have been improved in the last six months.
