woff-tools

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.
