How to use QR Scanner
- Choose an image containing a code to scan the selected file.

About this tool
QR Scanner decodes supported codes from an image you select or a camera session you start. Camera access requires browser permission; a successful decode is not guaranteed for every image.
The selected source is processed in your browser. Processing time and supported file sizes depend on the file and your device.
