About this tool
QR Gen runs entirely in your browser. QR Gen builds the QR code in your browser and lets you download it as an image.
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.
