How QR Code Generator works

QR codes encode data into a two-dimensional matrix of black and white squares. This tool uses the open-source qrcode.js library to generate QR codes entirely in your browser. When you enter data, the library converts it into a binary format, applies Reed-Solomon error correction (which lets the code remain scannable even when partially damaged), and renders it as a PNG image on a canvas element. The error correction level determines how much of the code can be damaged — ranging from 7% (Low) to 30% (High). Everything runs client-side; your data never leaves your device.
