WOFF2, explained
WOFF2 (Web Open Font Format 2) is a font wrapped in Brotli compression, built specifically for the web. Compared to a raw TTF/OTF, a WOFF2 is roughly 30% smaller — which means faster page loads and better Core Web Vitals. Every modern browser supports it.
When to use which format
- WOFF2 — your first choice for websites (@font-face).
- TTF / OTF — desktop apps, design software, and installing fonts on your OS.
- WOFF — only needed for very old browsers.
