Has anyone else noticed that 4chan allows webp for advertisers but not for users? I always keep hearing that webp isn't that much better for JPG but I'm not really convinced because I opened up my JPG screenshot in gimp, saved it to webp with 75% quality and I don't really notice a huge difference between the original JPG and the webp quality wise and I shaved off about 2MB so to me it looks like webp is about 50% more efficient than JPG.
