Back in ancient July I released a video that dug into how lossy and lossless image compression works and how to apply that knowledge to compress a set of different images for the web. Well, that's already out of date because AVIF has arrived. Brilliant. AVIF is a new image format derived from the keyframes of AV1 video. It's a royalty-free format, and it's already supported in Chrome 85 on desktop
