QR code best practices

Use high error correction for print/logo overlay, prefer SVG for scaling and test the code before printing.

Frequently asked questions

Which error correction level should I choose?

L (7%), M (15%), Q (25%) or H (30%); for print or logo overlay, H is recommended.

How do I create a Wi-Fi QR code?

Provide SSID, password and encryption type (e.g. WPA2); the code follows the WIFI: scheme.

PNG or SVG?

SVG scales losslessly and is ideal for print; PNG suits quick web usage.
