About this tool
There is no server behind QR Code Builder. QR Code Builder encodes your text into a QR matrix locally with an open-source library and renders it to a canvas.
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.
