## What it is
Google's reference C++ implementation of the WOFF2 font compression format, built on Brotli. It provides libraries plus CLI tools (woff2_compress, woff2_decompress) for converting between TTF/OTF and WOFF2 fonts.

## Use cases
- convert ttf fonts to woff2 for web use
- decompress woff2 font files back to ttf
- embed woff2 compression in a font toolchain
- reduce web font file sizes
- build font subsetting pipelines

## When to choose
- you need standards-compliant WOFF2 encoding or decoding
- you want a small C++ library to integrate into font tooling
- you need CLI batch conversion of font files

## When to avoid
- you need font rendering or shaping rather than compression
- you want a high-level font library with subsetting and feature inspection
- you work in a language without C++ interop and need a native port

## Facets
- artifact type: library
- maturity: maintenance
- function: compression, parser
- domain: web-development, files
- platform: windows, cpp, cli
- tags: woff2, font-compression, brotli, typography, web-fonts, fonts, linux, macos
