About this tool
QR Code Scanner App runs entirely in your browser. QR Code Scanner App 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. No data is sent anywhere, so it stays fast and private by default.
