font-spider is a Node.js CLI tool that intelligently compresses webfonts by analyzing HTML and CSS to find which glyphs are actually used, then subsets the fonts accordingly. It also converts fonts between woff2, woff, eot, svg, and ttf formats.
Use cases
- subset a webfont to only the characters used on my site
- compress ttf fonts to woff2 for faster page loads
- generate woff, eot, and svg versions of a font from a ttf file
- reduce font file size for Chinese or other large-character-set fonts
- analyze which fonts a web page uses
When to choose
- you serve custom webfonts and want minimal file sizes via glyph subsetting
- you need to convert a ttf file into multiple browser-compatible font formats
- your pages are static HTML/CSS that the tool can scan locally
When to avoid
- fonts are loaded dynamically or glyphs are rendered at runtime via JavaScript, so static HTML analysis misses characters
- you need a maintained solution - the project sees infrequent releases
- you work with non-web font workflows like desktop or print typography
