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
