About this tool
QR Scanner is a static, client-side tool with no backend. QR Scanner 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. Your input never leaves the page, and no account or install is required.
