fontTools is a Python library for manipulating font files, supporting TrueType, OpenType, AFM, and partially Type 1 and Mac-specific formats. It includes the TTX tool that converts fonts to and from an XML text format for inspection and editing.
Use cases
- convert ttf fonts to xml and back
- inspect opentype font tables programmatically
- subset a font to reduce file size
- merge or modify glyph data in python
- extract font metadata like names and metrics
- build variable fonts from designspace files
When to choose
- you need to read, write, or transform font files in Python
- you want to inspect or debug font binary tables via XML
- you're building font tooling like subsetting, merging, or instancing
When to avoid
- you just need to render text with a font rather than manipulate font files
- you need a GUI font editor rather than a programmatic library
