vdustr/font-splitter repository overview

⁠Font Splitter

Python library and CLI for splitting large font files into smaller unicode-range webfont subsets.

Font Splitter uses FontTools directly and can plan subsets from multiple ordered sources. For example, it can follow unicode-range declarations from a local font CSS file first, then place remaining codepoints into Unicode Block fallback ranges. It also supports the simpler Unicode Block plus max_codepoints flow for predictable default output.

⁠Current Package

This Docker image contains the Python implementation. Tags before v0.2.0 contain the legacy Node.js implementation.

The npm package is deprecated and no longer maintained. Use the Python CLI/API, GitHub release assets, or this Docker image for current usage.

See the GitHub repository for installation, CLI examples, Python API usage, release notes, and font license guidance:
