About this tool
There is no server behind QR Builder. QR Builder 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. No data is sent anywhere, so it stays fast and private by default.
