WOFF and WOFF2 are two font formats that are compressed and specifically created for the web. In terms of size, they are much smaller than TrueType or OpenType font files, allowing a much faster loading speed. WOFF has been used since 2009, and is supported by most web browsers such as Mozilla’s Firefox.

WOFF2 (or WOFF 2.0) was created in 2022, supported by more browsers like Google’s Chrome.
