      They use 3D graphs to show the Math.

    I usually have a script&#x2F;alias cmd to automatically convert images to webp. The webp format has pretty much replaced jpg&#x2F;jpeg (lacks transparency&#x2F;alpha support) and png (no compression) formats for me.<p>There is also AVIF format which is newer and better but it needs to still mature a bit with better support&#x2F;compatability.<p>If you are hosting images it is nice to use avif and fallback to webp.

      It is not that trivial, because there are tons of existing JPEG files and lossy recompression costs quality. (PNG does get replaced primarily because lossless WebP is kinda a superset of what PNG internally does.)
