Check, download, and generate favicons. Detects favicons via /favicon.ico, HTML <link> tags, and apple-touch-icon. Can generate SVG placeholder favicons from text.

Commands

Command	Description
check <url>	Check if a website has a favicon (tries /favicon.ico, HTML link tags, apple-touch-icon)
download <url> [output]	Download a site's favicon (tries direct, HTML parsing, Google API fallback)
generate <text> [size]	Generate an SVG favicon placeholder with text (1-2 chars, random background)
info <file>	Show image file info — size, MIME type, format (ICO/PNG/JPEG/GIF/SVG/WebP)

Examples

# Check if a site has a favicon
favicon check https://github.com
# → ✓ /favicon.ico — 200
# → ✓ apple-touch-icon found

# Download a favicon
favicon download [Technical Reference] google-icon.ico

# Generate an SVG placeholder
favicon generate "AB" 64
# → Creates AB-favicon.svg with random background color

# Get info about a favicon file
favicon info favicon.ico
# → Size, MIME type, format (detected from magic bytes)

Detection Methods

1. Direct: Checks <url>/favicon.ico
2. HTML Parsing: Looks for <link rel="icon"> and <link rel="shortcut icon"> in page HTML
3. Apple Touch Icon: Checks for <link rel="apple-touch-icon">
4. Google API (download only): Falls back to google.com/s2/favicons API

Requirements

• curl — for HTTP requests
• file (optional) — for MIME type detection in info command
• xxd (optional) — for magic byte detection in info command
