Privacy and Security

Your data security is our priority. All QR code generation happens directly in your browser using client-side JavaScript. Your data never leaves your device, ensuring complete privacy. This approach also means our generator works offline after the initial page load, making it perfect for sensitive information like WiFi passwords or personal contact details.

Best Practices for QR Code Usage

To ensure maximum scannability, maintain good contrast between the QR code and background. Test your QR codes with multiple devices before printing. For printed materials, ensure the QR code is at least 2cm x 2cm. Add a clear call-to-action near your QR code telling users what they'll get by scanning. Consider the scanning distance - larger QR codes can be scanned from further away.
