Glyphhanger is a Node.js CLI tool for web font optimization. It crawls web pages to determine which unicode-ranges are actually used, and can automatically subset web fonts accordingly.
Use cases
- subset web fonts to only the glyphs my site uses
- find which unicode-ranges a web page needs
- generate unicode-range splits for font-family fallbacks
- reduce web font file sizes for faster page loads
- audit font usage across a website
- automate font subsetting in a build pipeline
When to choose
- you want to shrink web font payloads by subsetting to used glyphs
- you need automatic unicode-range detection from live web pages
- you want a scriptable CLI for font optimization in CI
When to avoid
- you need a GUI font editor
- you work with non-web font formats like system font management
- you need actively maintained tooling with recent releases
