How It Works
Enter a URL, text message, or WiFi credentials (network name + password) and the tool generates a QR code in real time as you type. Customize the foreground and background colors and select from multiple size options.

Under the Hood
QR codes are generated using the qrcode.js library, which implements the QR Code Model 2 specification (ISO/IEC 18004). The library automatically selects the optimal encoding mode (numeric, alphanumeric, or byte) and error correction level (typically Level M: ~15% recovery capacity) based on the input data. The output is rendered as either a Canvas element (for PNG export) or an SVG element (for vector export).
