How do I optimize SVG files?

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

Is SVG optimization lossless?

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

What tools does optimo use for SVG?

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