How QR Code Generation works

The QR Code Generator creates scannable QR codes from URLs, text, contact information, Wi-Fi credentials, and more. The generated codes use Reed-Solomon error correction to remain scannable even when partially damaged or obscured.

Avoid mistakes

Common mistakes

A few things that can lead to misleading results or poor decisions.

Use the highest error correction level (H, 30%) when QR codes will be printed on materials that might get damaged. Use lower levels (L, 7%) for digital screens where clarity is guaranteed and you want maximum data density.
