## Questions fréquentes

### What is a WOFF2 file?

WOFF2 (.woff2, Web Open Font Format 2.0) is an improved web font format developed by Google and standardized by the W3C in 2018. It uses Brotli compression, achieving 30-50% smaller files than WOFF. WOFF2 is supported by all modern browsers and is the recommended format for web fonts.

### Are my WOFF2 files uploaded?

No. Font files you open from your device stay on your device and are rendered locally. Only the public sample font is requested from the server.

### Why should I use WOFF2 instead of WOFF?

WOFF2 uses Brotli compression which is significantly more efficient than WOFF's zlib, resulting in 30-50% smaller files and faster page loads. All modern browsers support WOFF2. Use WOFF only as a fallback for very old browsers.
