How do I optimize GIF files?

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

Is GIF optimization lossless?

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

What tools does optimo use for GIF?

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