Font Extractor

Extract all fonts used on a website and save them locally, organized by font family.

Workflow

Ask — confirm where to save fonts (default: ./fonts/)
Download — find and download all font files from the site
Organize — run the bundled script to sort them into family subdirectories

The heavy lifting of family detection is done by reading each font file's internal name table — no need to parse CSS family names.

Step 0: Confirm output location

Before downloading, ask the user where they'd like the fonts saved. Default to ./fonts/ if they don't have a preference. Use their chosen path in place of ./fonts/ throughout the remaining steps.

Step 1: Download all font files

Fetch the page HTML and find font file URLs. Use whatever approach gets the job done fastest:

Parse <link rel="stylesheet"> tags, fetch each CSS file, extract url(...) values from @font-face blocks
Check <link rel="preload" as="font"> tags
Search inline <style> blocks
If nothing turns up in CSS, search the JS bundle(s) for font file URLs (SPAs often embed them there)
If using Claude-in-Chrome (mcp__claude-in-chrome__*), read_network_requests will catch dynamically loaded fonts

Font file extensions to look for: .woff2, .woff, .ttf, .otf, .eot

Download every font file URL you find into ./fonts/ (flat). Use curl -L with a Referer header matching the page URL — many CDNs require it:

mkdir -p ./fonts
curl -L -H "Referer: <page-url>" -o "./fonts/<filename>" "<font-url>"

Download all unique URLs. Do not deduplicate — different URLs may be different versions or formats of the same font, and the user may want all of them.

Step 2: Organize by family

Run the bundled organize script. It reads each font file's internal metadata to determine its family name, then moves files into ./fonts/<family>/ subdirectories:

uv run ~/git/agent-skills/font-extractor/scripts/organize_fonts.py ./fonts

The script handles everything: reads the font name table, creates family directories, moves files. Fonts whose family can't be read get Unknown-1, Unknown-2, etc.

Step 3: Report

Show the user what was downloaded:

find ./fonts -type f | sort

Include the family count, file count, and total size.
