Desktop browser support for WOFF at 61,87 %

→ As of July 20, 2011 all major desktop browsers are now represented with a GA (General Availability) version offering WOFF support. This means all eyes are on the mobile browser market now.
It is worth mentioning though that specs for the WOFF format have not even been finalized yet. The WOFF specification was published as Candidate Recommendation on August 4, 2011.

Does your browser support WOFF fonts? If you see the frowning emoticon here above the answer is unfortunately a big fat nope. However if you do have WOFF support it will say so too.

At a glance: Right now, how many web users can see WOFF?
The graphic above represents the state of affairs for the month of August, 2012. IEv.9 came out on 15 March 2011 and is surprisingly slow to proliferate. Keep in mind that these statistics are more than a little skewed though, considering the huge popularity IE6 still enjoys in China.

How did we get here?
In the summer of 2009 Kombinat-Typefounders along with a large number of colleagues and friends at some of our favorite type foundries, publicly put our support behind the Web Open Font Format. Of the design firms on my personal radar edenspiekerman_ were certainly the first to put their name squarely behind WOFF. Now the design community's focus turned to the browser manufacturers who quickly started showing interest in supporting this new font format too. At this point all major dektop browsers support WOFF.

Microsoft Internet Explorer (53.6% usage share)

Last updated September 9, 2012
The GA version of IE9 supporting WOFF was made available world wide (localized language versions) on 15 March, 2011.
Microsoft was one of the parties submitting the WOFF format to the W3 Consortium on April 8 2010. Then on June 23 2010 the preview 3 build of IE9 showed up and indeed WOFF support was one of the new features. The release candidate (the last version before the official final build) was unveiled on February 10, 2011.

Apple Safari (4.64%)

Last updated September 9, 2012
With version 5.1, which is part of the Lion update, Safari is the last of the big browsers to finally implement WOFF support.

The technology purring under Safari's hood is called WebKit. On August 12, 2010 there was a "nightly build" of WebKit — version 5.0.1, an early beta release if you will — that supported WOFF.

• In spite of a major system update (v. 10.6.5) on November 11, 2010 and the latest discrete Safari update taking it to version 5.0.5 (made available on April 15, 2011) Safari still does not support WOFF.

Opera is one of the three organizations that submitted the WOFF format to the W3 Consortium.
