Frequently Asked Questions

Which error correction level should I choose for printing?

Level M (15%) is great for digital screens. If printing on physical surfaces that may get scratched or if overlaying a small center logo, choose Level H (30% error recovery).

Do generated QR codes ever expire?

No! These are static QR codes containing the raw URL or text directly inside the pixel matrix. They work indefinitely and never route through a redirect server.

Can I create a QR code to connect to a Wi-Fi network automatically?

Yes! Select the Wi-Fi mode, enter your network SSID and password, and scanning phones will connect directly without typing credentials.
