FontForge's user interface in 2012, using the Sky theme
|Stable release||20120731 / July 31, 2012|
|License||BSD license (Free software)|
FontForge (known until March 2004 as PfaEdit) is a full-featured font editor which supports all common font formats. Developed primarily by George Williams, FontForge is free software and is distributed under the 3-clause BSD license. It is available for several operating systems (including Linux, Windows and Mac OS X) and is localized into 12 languages.
To facilitate automated format conversion and other repetitive tasks, Fontforge implements two scripting languages: its own language and Python. FontForge can run scripts from its GUI, from the command line, and also offers its features as a Python module so it can be integrated into any Python program.
Fontforge supports Adobe's OpenType feature file specification (with its own extensions to the syntax). It also supports the unofficial Microsoft mathematical typesetting extensions (
MATH table) introduced for Cambria Math and supported by Office 2007, XeTeX and LuaTeX. At least one free OpenType mathematical font has been developed in FontForge (see below).
FontForge uses FreeType for rendering fonts on screen. Since the November 15, 2008 release, FontForge can use libcairo and libpango software libraries for graphics and text rendering providing anti-aliased graphics and complex text layout support.
The FontForge source code includes a number of utility programs in the 'fonttools' directory, including 'showttf' which shows the contents of binary font files, and a WOFF converter and deconverter.
FontForge supports a wide variety of font formats. Its native "spline font database" format (
.sfd file name extension) is text-based and facilitates collaboration between designers, as difference files can be easily created. The software supports many other font formats and converts fonts from one format to another. Supported font formats include: TrueType (TTF), TrueType Collection (TTC), OpenType (OTF), PostScript Type 1, TeX Bitmap Fonts, X11 OTB bitmap (only sfnt), Glyph Bitmap Distribution Format (BDF), FON (Windows), FNT (Windows), and Web Open Font Format (WOFF). FontForge also imports and exports fonts to and from the Scalable Vector Graphics (SVG) format and the Unified Font Object (UFO) format.
