About this tool
Gen QRCode runs entirely in your browser. Gen QRCode 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. Nothing you enter is uploaded, and it keeps working offline once the page has loaded.
