fnt2

fnt2 is a font file processing tool designed to assist designers and developers in manipulating, converting, and analyzing digital font assets. While not tied to a single vendor, it aims to cover common font formats and workflows encountered in desktop publishing, web typography, and game development. The project emphasizes a clean command-line interface and a modular architecture to support repeatable tasks in automated pipelines.

Supported formats include TrueType, OpenType, and their web formats WOFF and WOFF2, as well as legacy bitmap fonts used by embedded systems. fnt2 can perform format conversion, subsetting to reduce file size, and extraction of font metrics, kerning data, and glyph outlines for inspection or tooling integration.

Key features include batch processing, scriptable operations via a simple API, and extensible parsing backends that allow adding new font formats. The tool emphasizes deterministic output, verbose logging, and non-destructive transformation of inputs to preserve original assets in development workflows.

Originating in the open-source community, fnt2 is maintained by volunteer contributors and documented to encourage interoperability with existing font tooling. It is distributed under an open-source license, with ongoing updates guided by users and contributors.

In practice, fnt2 serves as a utility within font pipelines, enabling automated asset preparation, quality checks, and pipeline integration for designers, developers, and researchers. Its neutral design aims to complement established font editors and rendering engines rather than replace them.
