FontTools/TTX for Windows

This page contains TTX for Windows builds, maintained by Adam Twardoch.

TTX decompiles TrueType and OpenType fonts to an XML-based text format (also called "TTX") and back, enabling you to edit fonts with a plain text editor.

On this page, you can find the Windows binary build of TTX (Windows "EXE") which does not require Python or any additional components. This version of TTX works fine on Windows 2000/XP and should also work on Windows 98/ME.

McMillan Installer rather than py2exe was used to build ttx.exe, but McMillan Installer is no longer developed, so the newer builds will use py2exe.

Usage

To convert any OpenType or TrueType font (.otf or .ttf) into an XML file (.ttx) or vice versa:

• drag the file onto the TTX icon on your desktop,
• right-click on the file and choose Send To / TTX,

Command-line use:

• Type ttx thisfont.otf to produce a file thisfont.ttx that contains an XML representation of the entire font file.
• Type ttx thisfont.ttx to convert the XML file back to a working thisfont.otf or thisfont.ttf (depending on the font flavor)
• Type ttx -t GSUB -t GPOS thisfont.otf to produce a file thisfont.ttx that only contains the XML representation of the OpenType Layout tables GSUB and GPOS. This is particularly useful if dumping of the entire font file fails for whatever reason, of if the resulting .ttx file for the entire font file is very large. This is also useful if you would like place exactly the same table (e.g. cmap) in several fonts.
• Rename the .ttx file to thisfont2.ttx and type ttx -m thisfont.otf thisfont2.ttx to produce a new file thisfont2.otf that is identical to thisfont.otf except that some tables were replaced by new versions that were defined in thisfont2.ttx. Use this to re-use the same table information (e.g. for cmap) in several fonts.
• Type ttx in the command-line to get more information about the command-line syntax.
