The Web Open Font Format (WOFF) is a font format for use in web pages. It was developed during 2009[2] and is in the process of being standardized as a recommendation by the World Wide Web Consortium (W3C) Web Fonts Working Group.[3]
WOFF is mostly TTF with compression and additional metadata. The goal is to support font distribution from a server to a client over a network. This means that bandwidth is an important parameter.

[edit] Submission as a standard
Following the submission of WOFF by the Mozilla Foundation, Opera Software and Microsoft on April 8, 2010,[4][5] the W3C commented that it expects WOFF to soon become the "single, interoperable [font] format" supported by all browsers.[6] The W3C published WOFF as a working draft on July 27, 2010.[7][8] Later on August 04, 2011 the W3C published WOFF as Candidate Recommendation.
[edit] Specification
WOFF is essentially a wrapper that contains sfnt-based fonts (TrueType, OpenType, or Open Font Format) that have been compressed using a WOFF encoding tool to enable them to be embedded in a web page.[2] The format uses zlib compression (specifically, the compress2 function),[2] typically resulting in a filesize reduction from TTF of over 40%.[9] Like OTF fonts, WOFF supports both Postscript and TrueType outlines for the gylphs[10].
[edit] Vendor support
The format has received the backing of many of the main font foundries[11] and has been supported by all major browsers:
- Firefox since version 3.6[12]
- Google Chrome since version 6.0,[13]
- Opera since version 11.10 [14] (Presto 2.7.81).[15]
- Konqueror since KDE 4.4.1.[16]
- Internet Explorer 9,[17]
- Safari[18] 5.1.[19]
- other WebKit-based browsers since WebKit build 528.[20][21]
