woff-tools

OTF to WOFF · WOFF to OTF · TTF to WOFF · WOFF to TTF

Node.js font converter capable of converting SFNT (TrueType, OpenType) font files to WOFF and vice-versa.

Forked from https://github.com/odemiral/woff2sfnt-sfnt2woff and added some clearer documentation, a package.json and added to npm.

woff2sfnt-sfnt2woff is based on an Ubuntu package woff-tools, which contains the two commands woff2sfnt and sfnt2woff. As far as I can find, this Ubuntu package is the original package released with woff by Mozilla. I came across this project and gave it a small cleanup before releasing it, but if you'd like me to do a full refactor and cleanup of deprecated code and performance tweaks, and make a better CLI, give this project a star :)
