Most websites, image management and optimization are going to be the biggest thing to help and aid in web performance. WebP was an introduced nearly 10 years ago at this point. It took a long time for the format to gain any traction at all. I started when Firefox started adopt the format last year.

Last month, at WWDC Apple announced that the latest Safari will support webP images this fall. This is big news because now all major browsers support the format as well as another less step, we will eventually have to polyfil.
