How do I optimize AVIF files?

Run "npx optimo image.avif" in your terminal. Optimo applies format-specific ImageMagick-powered compression that reduces AVIF file size while preserving quality. The original file is kept if the optimized output is not smaller.

Is AVIF optimization lossless?

By default, optimo uses lossless optimization for AVIF. For additional compression, add the --lossy flag to allow minor quality trade-offs for significantly smaller files.

What tools does optimo use for AVIF?

Optimo uses ImageMagick, MozJPEG, and SVGO (depending on format) under the hood with format-specific settings tuned for AVIF files.
