What is WOFF2?
WOFF2 (Web Open Font Format 2) is the most efficient font format for the web. It uses Brotli compression to produce files that are typically 30–50% smaller than their TTF or OTF equivalents, with no loss in visual quality. All modern browsers support WOFF2, making it the recommended format for web typography.
Why Convert TTF/OTF to WOFF2?
- Faster page loads — smaller file sizes mean fonts download quicker, improving your Core Web Vitals score.
- Better SEO — Google's PageSpeed Insights recommends serving fonts in WOFF2 format.
- Universal browser support — Chrome, Firefox, Safari, Edge and all modern mobile browsers support WOFF2 natively.
- No quality loss — WOFF2 is a lossless compression wrapper, so glyphs look identical to the original TTF/OTF.
