Encodes images into AVIF — a modern format that, at comparable quality, weighs roughly half of JPG, which directly speeds up page loads.
For example: You want to speed up your website — convert your images to AVIF and the same product photos will weigh about half as much at visually identical quality.
Who uses it most: Web developers, SEO specialists, site owners, performance engineers
All current versions of Chrome, Firefox, Edge, and Safari support AVIF. For very old browsers, it's worth keeping a JPG or WebP fallback.
The AVIF encoder (a WebAssembly module called libavif) downloads and compiles right in your browser the first time you use it — every conversion after that is faster.
