Create downloadable QR codes for links, text, phone numbers, and more.
The QR Code Generator creates scannable QR codes from any text, URL, phone number, or other data. QR codes (Quick Response codes) are two-dimensional barcodes that any smartphone camera can scan instantly. Common uses: linking printed materials to websites, sharing Wi-Fi credentials, adding contact information (vCard), creating payment links, and tracking marketing campaigns with unique URLs per printed piece.
A QR code can store up to 4,296 alphanumeric characters or 7,089 numeric characters. For URLs: keep them as short as possible. Long URLs make denser QR codes that are harder to scan in poor light or at small sizes.
Minimum recommended print size: 1 cm × 1 cm (0.4 inch). At this size, a modern smartphone camera can scan it from about 20 cm away. For business cards: 2 cm × 2 cm minimum. Always test print at the intended size before bulk printing.
QR codes have built-in error correction (up to 30% of the code can be obscured and still scan). This allows embedding a small logo in the center. Custom colors are also possible — but ensure sufficient contrast between the dark modules and light background.
