FontForge -- An outline font editor
that lets you create your own postscript, truetype, opentype, cid-keyed,
multi-master, cff, svg and bitmap (bdf, FON, NFNT) fonts, or edit existing
ones. Also lets you convert one format to another. FontForge has support
for many macintosh font formats.
FontForge's user interface has been localized for: (English), Russian, Japanese,
French, Italian, Spanish, Vietnamese, Greek, Simplified & Traditional
Chinese, German, Polish, Ukrainian and Catalan.
This website itself has been translated into Japanese
and the tutorial into traditional Chinese
. Translations are often out of date, I fear.
I have no one to do QA for me except users on the net, so this is essentially
(and eternally) beta software. Expect to find bugs. Please
let me know when you do (this is a public mailing list).

There are currently three mailing lists established for FontForge. You may
subscribe to any of them on sourceforge:
You may not post to a list until you have subscribed (sorry about that, but
we were getting too much spam).
Caveat: Posting to these mailing lists exposes
your email address.
FontForge is by no means perfect. And probably has some bugs. Be prepared
to save frequently and consider working on a copy of the original.
No attempt has been made to be efficient.
Many type 3 fonts will not be read in correctly
Importing a type0 font loses the encoding. FontForge only imports simple
type0 fonts (such as those made by itself), will get confused if there's
more than one font with a chars dictionary.
FontForge's does not support contextual ligatures for Apple Advanced Typography
There are a number of opentype/AAT tables which FontForge does NOT support.
|O, don't the days seem lank and long
When all goes right and nothing goes wrong,
And isn't your life extremely flat
With nothing whatever to grumble at!
Princess Ida, Act III, W.S. Gilbert (& Sullivan)
This list includes the gross bugs that I'm aware of but don't know how to
fix. Minor bugs get reported to me and are generally fixed within a week
and rarely appear on this list.
Some truetype fonts (kaiu and mingliu) do not store the correct outline.
Instead they rely on using the instructions to move points around to generate
the outline. The outline does not appear to be grid-fit at all, just positioned.
FontForge does not apply the instructions when loading. In most fonts this
would be the wrong thing to do, and I don't know how I could tell when it
needs to be done...
After adding the Johab encoding 23/Nov/01, any old fonts (in sfd files) which
had a unicode encoding will suddenly claim to have a Johab encoding. I don't
see a way around this at the moment. Just reencode them as unicode and all
should be well.
I'm told AutoKern doesn't work too well. (I may have fixed this, but
I'm not sure)
FontForge is confused by small splines, on the order of one em unit. If you
need something that small, scale the font up by a factor of 2 or more (including
the ascent and descent).
There is a fundamental problem when importing a type3 font (or an eps file).
In an most postscript programs each contour is stroked or filled individually,
but in a type1 character, all contours are filled together. This can lead
to unexpected side-effects if contours overlap. (configuring fontforge for
mutlilayered editing can help with this)
On linux boxes the dashed lines representing hints or the outlines of references
get screwed up. I think this is a bug in the XServer on linux (it doesn't
happen on other systems) but I have not examined it closely.
FontForge will not copy and paste large (>XServer transfer (4Meg on my
machine)) clipboards of text.
Under gnome mnemonics in menus don't work. Personally I consider this a bug
Under gnome, docked palettes don't work the first time. Personally I consider
this a bug in gnome.
FontForge only produces an approximation to the OS/2 Codepages fields.
Some commands don't work well in extreme
I'm sure you'll find some. If you can isolate it and come up with a reproducible
minimal case, that would be great. If your executable has symbols in it,
you could run it in gdb and get a stack trace... Give me a test case if possible.
Do what you can.
My writing leaves much to be desired. Anyone who can make my
documentation more readable is encouraged to do so. (or who wishes to translate
it into other languages, or who wishes to put it into a more flexable format,
KANOU has a Japanese version)
I also have a brief tutorial in pdf
format and in html. This could also
be translated into other languages (and would be a simpler job than trying
to translate the entire website). The html has been translated into
The UI can be translated into different languages. FontForge now
uses gnu gettext. See the section on

Different font formats
FontForge supports Type1, truetype, opentype, cff, type42, cid-keyed and
svg fonts, also bdf and NFNT for bitmaps
FontForge will sort-of accept metafont files (essentially it runs metafont
and autotraces the result). It won't produce .mf files
FontForge will read (but not produce) Ikarus files
FontForge will read acorn font files with a helper app.
But there are other formats out there that I can't find descriptions of or
don't think are worth supporting
Can you point me at documentation for other standards
Can you explain why that format is useful?
There are certain commands which don't
work very well and if someone else wanted to they might code them better
Remove overlap (has problems with coincident splines)
Expand Stroke (has problems when there are sharp bends near the end of a
contour (or near a joint where the slope is discontinuous) -- a sharp bend
is one where the radius of curvature is smaller than half the stroke-width)
Autokern (might be fixed now)
Change Weight & Condense/Extend make assumptions about glyphs that aren't
I'd like to provide a reasonable bibliography, please suggest some good relevant
Are there any other programs or websites that I should be mentioning?
I find QA boring, and since no one is paying me for this I don't do very
much (I generally run it past my testsuite from time to time). This is obviously
a problem. If anyone (or several anyones) wants to undertake to do QA
for me I'd be
delighted (this is a public mailing list).
I'm always on the look out for short copyright free texts for printing. I'm
looking for samples from languages I don't have anything on, or in styles
that I don't have.
I'm also interested in phrases equivalent to "The quick brown fox jumps over
the lazy dog." (pangrams). These are short sentences which use every letter
in the script.
Indic languages have a series of special ligature features in opentype. I
believe that FontForge could probably generate some of these by default but
I don't know enough to say which. If you are familiar with Indic scripts
could you give me a list of conversions in a format like
U+0066 + U+0069 => U+FB01 'liga'
The sample text in File->Print comes from many
The following people have helped debug fontforge. Many thanks! (actually
the list should be far longer than this, but as time goes on there are just
too many people to thank)
University of California, Santa Barbara
(which has several times let me use some of their machines to do builds and
find bugs if I didn't have the requisite system at home).

job than I could have.

FontForge was inspired by AltSys's
now rescued from MacroMedia by FontLab. Godfrey DiGiorgi encouraged me to
buy my first copy of Fontographer in the mid-80s.
My father inspired a general interest in typography (though he is interested
in renaissance printing techniques rather than computers).

which company has given me the free time to write this program.

It is also available bundled with his
Xgridfit aims to relieve some of the tedium of instructing fonts by providing
such amenities as named points, control values, variables and functions,
high-level programming structure, and automatic management of stack and reference
TTX provides a
way of editing all the strange tables in an opentype font (by converting
them from/to XML)

And Adobe provides a

Other font tools of mine
fondu -- Unwraps fonts from mac resource
files (this includes dfonts). Produces ttf, pfb and bdf files for 'sfnt',
'POST' and 'NFNT' resources
mensis -- Allows the user much finer
control over some truetype tables than is provided by FontForge.
-- Dumps the contents of a truetype/opentype font. Does some error checking
-- Reads a pcl file (to go to an HP printer) and extracts any truetype or
bitmap fonts in it. (the bitmap fonts become bdf files, the truetype fonts
become ttf files).
