QR Code Generator & Reader illustration

QR Code Generator & Reader

Generates QR codes from URLs, text, Wi-Fi credentials and vCards with adjustable size, colours and error correction, and decodes QR codes from uploaded images or screenshots.

Runs 100% in your browser — images never leave your device.

Notes

  • Higher error-correction levels survive more damage and overlays but need denser modules. Level M is the everyday default.
  • Everything runs locally in your browser; your images are never uploaded to any server.
