Overview
WOFF (Web Open Font Format) is a font format specifically designed for use on web pages. It wraps TrueType or OpenType fonts with compression (typically zlib) to reduce file size while maintaining all font data and features.
Developed collaboratively by Mozilla, Microsoft, and Opera, WOFF became a W3C Recommendation in 2012. It includes metadata support and licensing information, making it ideal for web font distribution.
WOFF provides excellent compression (typically 40% smaller than TTF) while maintaining compatibility with existing font tools and renderers.
Common Use Cases
Recommended For
- • Web typography and @font-face
