How it works

A QR code is a matrix barcode that can encode text and actions like opening a URL or joining Wi-Fi. offQR supports URL, text, Wi-Fi, email, phone, SMS, vCard, and geo payloads.

Error correction adds redundancy. Higher levels (Q/H) let scanners recover from small damage, overlays, or logo cutouts, but may increase code density.

The quiet zone is the empty margin around the QR pattern. Keep it visible for reliable scans, especially in print.

If you place a center logo, prefer higher error correction and test scans on multiple devices. For exports, 512 px is good for digital use, while 1024 px+ is safer for posters or print.
