About the 3D QR code maker

Turn a link or your guest WiFi login into a QR code you can print. Guests point their phone camera at it to connect.

  • Print the plate light and the squares dark, or the other way round with enough contrast.
  • Short links make bigger, easier squares.
  • Always scan the print before you hand it out.

Everything runs in your browser: nothing is uploaded and there is no sign-up.
