Error correction allows QR codes to be scanned even if they are partially damaged or covered. Slabs range from L (7% recovery) to H (30% recovery).
Can I generate QR codes for Wi-Fi networks?

Can I add a custom logo to the QR code?
Yes. You can upload a custom logo to display in the center of the QR code.
What is the best color contrast for QR codes?
For reliable scanning, use dark modules on a light background. Scanning devices require sufficient contrast to read the code.
