Wonder what happened to the WebP format from Google? Last when I tried using it, there were no nice image converters that would convert my PNGs into WebP properly. Any live websites using it?
Mozilla is still against it. Makes me kinda angry, actually. They killed MNG/JNG, because it added like 100kB to the installer and because we should just use Flash instead (seriously). It's now a decade later and we still don't have a lossy RGBA format. If quantized PNG8s aren't good enough, you can only use gigantic PNG32 files, which are over 5 times larger than JNG or WebP files. I've seen websites which were over…
background-image: image("wavy.svg", 'wavy.png' , "wavy.gif"); and so on...
It seems that Google lowered emphasis on the project, or is still working on it behind-the-scenes. I'd much prefer to have 'less of images' moving over the web (without cutting back on visuals, you know) and save precious bandwidth.

And then the fact that Google Chrome has over 30% market share. Makes sense to promote WebP.
