About this tool
Barcode Builder runs entirely in your browser. Barcode Builder 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. No data is sent anywhere, so it stays fast and private by default.
