(how it rendered in Chrome) Is it Chrome-related or did the OP compress with bad settings? As for the TestWebP iOS lib itself, it takes 25 LOC to load an image, which takes 1 LOC with system libraries. Somebody needs to go in and put a category on UIImage to do the heavy lifting. I just ran a grep across about 15 iOS apps I develop and the average size of art assets is about 1MB. So this is a neat hack, and I am sure there are apps out there with 300MB in art assets that could benefit from it. But for the typical app, not worth the effort.
