There is webpjs I think.

http://webpjs.appspot.com/

Basically if a browser does support webp, the script does nothing, but otherwise I think this script ends up supporting the image via javascript.

Please don’t drain my battery with crap like this when my phone has dedicated hardware for JPEG decoding.

That script won't even run unless it's on a browser which doesn't support webp.

I don't have to support ios/safari.
