    What is a WOFF file?

    WOFF (Web Open Font Format) became a W3C recommendation in 2012. It wraps the tables of a TTF or OTF font and compresses each one with zlib, typically saving around 40% compared with the raw font.

    WOFF2 has largely replaced it, but WOFF remains a safe fallback for very old browsers. ConvertCove reads and writes WOFF using its own implementation of the W3C specification.
