WOFF becomes the W3C Recommendation
This document specifies the WOFF font packaging format. This format was designed to provide lightweight, easy-to-implement compression of font data, suitable for use with CSS @font-face rules. Any properly licensed TrueType/OpenType/Open Font Format file can be packaged in WOFF format for Web use. User agents decode the WOFF file to restore the font data such that it will display identically to the input font.
The WOFF format also allows additional metadata to be attached to the file; this can be used by font designers or vendors to include licensing or other information, beyond that present in the original font. Such metadata does not affect the rendering of the font in any way, but may be displayed to the user on request.
The WOFF format is not intended to replace other formats such as TrueType/OpenType/Open Font Format or SVG fonts, but provides an alternative solution for use cases where these formats may be less optimal, or where licensing considerations make their use less acceptable.
