What is it
The successor to WOFF with significantly better compression — 30-50% smaller files thanks to Brotli compression. WOFF2 is the current standard for web fonts and the only format you should be serving in production. Every modern browser supports it (Chrome, Firefox, Safari, Edge). The font data inside is identical to TTF or OTF; WOFF2 just wraps it in a web-optimised, compressed container. Smaller files mean faster page loads, which means better user experience and better Core Web Vitals scores.

FAQ
Should I use WOFF or WOFF2 on my website?
Use WOFF2 as primary with WOFF as fallback. WOFF2 is 30-50% smaller and supported by every modern browser. You only need WOFF as a fallback for very old browsers.
Can I install WOFF2 fonts on my computer?
Not directly on most systems — WOFF2 is designed for web use. Convert to OTF or TTF for desktop installation. Some newer OS versions can handle WOFF2 installs, but desktop font formats are more reliable.
