WiFi network (scannable by phones)

python3 scripts/generate_qr.py "wifi" --wifi-ssid "MyNetwork" --wifi-pass "secret123" -o wifi.png

vCard contact

Generate the vCard string and pipe it:

python3 scripts/generate_qr.py "BEGIN:VCARD
VERSION:3.0
FN:Jane Smith
TEL:[phone]
EMAIL:[e-mail]
END:VCARD" -o contact.png

ASCII art (terminal preview)

python3 scripts/generate_qr.py "hello" --format ascii

SVG (scalable, web-friendly)

python3 scripts/generate_qr.py "data" -o code.svg

Options

• -o FILE — output path (default: qr.png)
• -s N — box size in pixels (default: 10)
• --border N — border width (default: 4)
• --format png|svg|ascii — force format (auto-detected from extension)
• --error-correction L|M|Q|H — error correction level (default: M; use H for logos/damage tolerance)
