Better Portable Graphics
You can see how unbelievably better this is than JPG (at almost any file size) here:http://xooyoozoo.github.io/yolo-octo-bugfixes/#swallowtail&j...Or here:https://bellard.org/bpg/lena.htmlThe difference between webp from the first link is actually quite small (http://xooyoozoo.github.io/yolo-octo-bugfixes/#swallowtail&w...).Additionally you can find the Javascript decoder here:https://github.com/xingmarc/bpg-decoderIt's 215k of Javascript though so isn't really that practical in most cases and I'd worry about how it was affecting battery life. It'd be very interesting to do some tests and see.
