Pro Tips

  • Use high contrast colors (dark foreground, light background) for best scannability.
  • Keep logos small (10-20% of QR code size) to maintain scanning reliability.
  • Test your QR code with multiple devices before printing or publishing.

Common Issues

QR code won't scan?

Ensure there's enough contrast between foreground and background colors. Avoid very light or very similar colors. Also, check that the logo isn't too large.

Logo looks distorted?

Use square or circular logos for best results. Adjust the logo size slider to find the optimal balance between visibility and scannability.
