This document specifies a simple compressed file format for fonts, designed primarily for use on the web. The WOFF format is directly based on the table-based sfnt structure used in TrueType[1], OpenType[2] and Open Font Format[3] fonts, which are collectively referred to as sfnt-based fonts. A WOFF font file is simply a repackaged version of a sfnt-based font in compressed form. The format also allows font metadata and private-use data to be included separately from the font data. WOFF encoding tools convert an existing sfnt-based font into a WOFF formatted file, and user agents restore the original sfnt-based font data for use with a webpage. In general, the structure and contents of decompressed font data should match that of the original font file. Tools producing WOFF font files may provide other font editing features such as glyph subsetting, validation or font feature additions but these are considered outside the scope of this format. Independent of these features, both tools and user agents must assure that the validity of the underlying font data is preserved.
