How it works
The image is drawn to a local canvas and QR pixels are passed to a browser-side decoder.
Input stays in the browser. The static page can be deployed independently for its own host or later custom domain.
Read QR codes from images.
Upload a QR image and decode it locally in the browser. No uploaded file is sent to a server.
