Fetch Favicons

Retrieve favicons for any domain using multiple sources with automatic fallback.

Requirements

Python 3.6+
requests library: pip install requests

Quick Usage

python3 scripts/fetch_favicon.py example.com
python3 scripts/fetch_favicon.py example.com --output ./icons/
python3 scripts/fetch_favicon.py example.com --size 128

Sources (in order of preference)

Source	URL Pattern	Notes
Google	`https://www.google.com/s2/favicons?domain={domain}&sz={size}`	Best quality, supports sizes
DuckDuckGo	`https://icons.duckduckgo.com/ip3/{domain}.ico`	Privacy-focused, no size param
Direct	`https://{domain}/favicon.ico`	May be low quality or missing

Parameters

domain: Target domain (e.g., github.com). Full URLs are automatically parsed to extract domain.
size: Size hint for Google API (16, 32, 64, 128, 256). Default: 128. Falls back to 16x16 if unavailable.
output: Output directory. Default: current directory.

Output

Returns PNG format (Google) or ICO format (DuckDuckGo/direct)
Filename: {domain}.png or {domain}.ico
Exits with code 0 on success, 1 on failure

Examples

# Single domain
python3 scripts/fetch_favicon.py github.com

# From full URL (domain extracted automatically)
python3 scripts/fetch_favicon.py "https://docs.github.com/en/pages"

# Custom size and output
python3 scripts/fetch_favicon.py twitter.com --size 256 --output ~/icons/

# Batch fetch (one per line in file)
cat domains.txt | xargs -I {} python3 scripts/fetch_favicon.py {} --output ./favicons/

Rate Limiting

Google's API may rate-limit after ~55 consecutive requests. Add delays for batch operations:

cat domains.txt | while read domain; do
  python3 scripts/fetch_favicon.py "$domain" --output ./favicons/
  sleep 0.5
done
