What is a WOFF file

WOFF files mostly belong to FontForge by FontForge Developers. A WOFF file is a font saved in Web Open Font Format (officially WOFF Version 1.0). It provides a compressed solution for embedding an OpenType or a TrueType font in a web page. WOFF fonts were developed in order to distinguish fonts intended for web use from those intended for desktop use and to reduce the latency of fetching fonts from a server. It can be ported into a CSS file using @fontface rule. Compared to uncompressed TrueType and OpenType fonts, WOFF files are compressed so they take less bandwidth. Most browsers support WOFF format.

How do you open WOFF files?

You need a suitable software like FontForge to open a WOFF file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your WOFF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a WOFF file directly in the browser:. Just drag the file onto this browser window and drop it.

WOFF file format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Knowledge is power - this also applies when dealing with unknown or faulty files. Below is our analysis of the WOFF files:

WOFF is one of the most common file extensions and is primarily used by a single program. The two most popular formats are as follows:

97% of all WOFF files are Web Open Font Format files. These are binary files, so they do not contain words or text. The average file size is 33 KB with most files being between 6 KB and 98 KB in size. The file type is relatively new. The files contain the following words: wOFF, cmap, glyf, GDEF, FFTM, gasp, GSUB, head, GPOS, hhea and cvt. These files are attributed to regular, icons, webfont, bold, sans, fontawesome, font and light.

All other WOFF files (3%) have no uniform format. Sometimes used for icomoon, black, glyphicons, medium, halflings, material, italic or icon. If you want to find out what your WOFF file contains, drag and drop it onto this page.
