About formats

WOFF

WOFF (Web Open Font Format) is a font format designed for use in web pages, standardized by the W3C. WOFF wraps TrueType or OpenType font data with compression and metadata, reducing download size while preserving quality. WOFF is supported by all modern browsers and is the recommended format for serving custom web fonts via @font-face.
