TTX Font Format File

The TTX Font Format File (TTX) is an XML-based file format used to store data for TrueType and OpenType font files. TTX files offer access to and enable editing of TrueType and OpenType font data, such as character outlines and font metadata, as well as extraction of subsets of a font for reduced file sizes.

TTX files can be used to view and edit the internal structure of TrueType and OpenType font files, making it a valuable tool for font developers, designers, and engineers who wants to inspect the font and find font-related issues.

Additionally, TTX allows for the conversion of TrueType and OpenType fonts to and from other font formats, such as SVG and WOFF. This can be useful when working with web fonts, as it allows for greater control and optimization of file size.
