🖼️ svico

An SVG to ICO converter optimized for the smallest lossless output

svico renders the SVG into PNG layers at each requested size, losslessly compresses them with oxipng, and assembles them into a single .ico file.

🕹️ CLI

cargo install svico

or download a prebuilt binary

Usage: svico <input.svg> [options]

  -o, --output <path>  Output .ico path [<input>.ico]
  -s, --sizes <list>   Comma-separated sizes in 1..=256 [16,24,32,256]
  -h, --help           Print help
