This reduces font file size without changing the visual appearance of glyphs. It is based on the AFDKO tx tool from Adobe and wraps that functionality for Python users.\n\nThe package depends only on fontTools and runs on Python 3.10 and later across Windows, macOS, and Linux. It is actively maintained and marked as production-stable. The project is small but focused, with no known security vulnerabilities.","worth_installing":"Yes, if you work with CFF fonts and need to reduce file size. The package is actively maintained, has no security issues, uses a permissive license, and solves a specific problem well. Install friction is moderate but manageable; the single dependency is standard in font tooling. Not necessary if you don't work with CFF fonts or already use other font optimization tools."},"id":"cffsubr","links":{"html":"https://skillfed.io/packages/cffsubr","md":"https://skillfed.io/packages/cffsubr.md","pypi":"https://pypi.org/project/cffsubr/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-12-05","license_spdx":null,"license_treatment":"permissive","name":"cffsubr","python_support":"supports_current","summary":"Standalone CFF subroutinizer based on the AFDKO tx tool"},"popularity":{"monthly_downloads":94721,"position":13311,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.4.0"}
