About this tool
Barcode Generator runs entirely in your browser. Barcode Generator builds the QR code in your browser and lets you download it as an image.
Higher error-correction levels (Q or H) survive damage or partial cover at the cost of denser modules; level M suits most links. Nothing you enter is uploaded, and it keeps working offline once the page has loaded.
