What is This Tool?

A QR code generator creates scannable Quick Response codes for URLs, text, Wi-Fi credentials, contact cards, and more. Customize colors, size, error correction level, and add logos to produce branded QR codes ready for print, packaging, and digital use.

QR codes use Reed-Solomon error correction to remain scannable even when partially damaged — up to 30% of the code can be obscured at the highest error correction level (H). This is what enables logo placement in the center of QR codes without breaking functionality.

Frequently Asked Questions

What data types can I encode?

URLs, plain text, Wi-Fi credentials (SSID/password), vCards, email addresses, phone numbers, SMS, and geographic coordinates.

Can I add my logo to the QR code?

Yes. Using high error correction (level H), you can place a logo in the center covering up to 30% of the code while maintaining scannability.

What size should I print QR codes?

Minimum recommended print size is 2×2 cm (0.8×0.8 inches). For scanning at distance, increase size proportionally — about 10:1 distance to size ratio.
