No matter how much unnecessary css/js or general load time I shave off my website, Google Audits always penalises me massively for not using "next-gen formats" such as JPEG2000, JPEGXR and WebP in my pages.
So, fine, I thought, I'll add support for those. But both JPEG2000 and JPEGXR are barely supported (respectively by Safari and IE only) while Webp is supported by everything BUT Safari.
So what's the solution here? Am I supposed to have a bunch of media queries for specific edge cases to make this work on every browser? Surely Google wouldn't ask people to do this unless support was at a point where it was actually feasible.
I'm open to suggestions, any way to easily target all browsers that support WebP?
