Create custom QR codes for links, text, WiFi, contact cards and more — fully offline in your browser.
A QR code (Quick Response code) is a 2D barcode that can store URLs, text, contact details, WiFi credentials, and more. Most smartphones can scan them directly with the camera app.
Levels L, M, Q, H allow the QR code to be read even if it’s partially damaged. Higher error correction uses more modules, making codes denser but more robust (H ≈ 30% recovery).
Keep good contrast (dark foreground on light background), avoid inverting colors, and ensure the printed QR is at least 2 cm (0.8 in) wide for reliable scanning at normal distances.
This tool generates QR codes entirely in your browser using JavaScript. Your data is not sent to any server or stored remotely — only an optional local history is kept in your device.
