Script for generating optimised favicons from an SVG using open source tools. The code accompanies the post on open source favicon generation. If you have any questions, please drop a comment at the bottom of that page.

This script uses Inkscape, OptiPNG and Scour so you need these installed to run it.

On macOS, you can install them with Homebrew:

brew install inkscape optipng scour

Once you have the apps installed, just run the script:

sh optimised-favicon-generator.sh input-svg-file.svg

This creates the optimised favicon files:

• output/apple-touch-icon.png
• output/favicon.ico
• output/icon.svg
• output/icon-192.png
• output/icon-512.png

which are the five favicon files needed for wide support in legacy and modern browsers. More details in the post mentioned above.
