About this tool
QR Code Scanner runs entirely in your browser. QR Code Scanner encodes your text into a QR matrix locally with an open-source library and renders it to a canvas.
Because the code is generated on your device, you can encode private links or data without sending them anywhere. It behaves the same on desktop and mobile, with nothing stored remotely.
