Frequently Asked Questions

Is this QR Code Generator free?
Yes, the QR Code Generator is completely free to use. Generate unlimited QR codes for URLs, text, WiFi credentials, and more without any registration, watermarks, or usage restrictions.
Is my data private when generating QR codes?
Yes, QR code generation happens entirely in your browser. The text or URL you encode is never sent to any server. The QR code is generated client-side using JavaScript, and the resulting image stays on your device until you choose to download or copy it.
What can I encode in a QR code?
You can encode any text including URLs, plain text, email addresses (mailto:), phone numbers (tel:), SMS messages, WiFi network credentials, and more. The tool includes quick templates for common formats. Most smartphone cameras can scan QR codes and automatically handle these special formats.
What size should my QR code be for printing?
For reliable scanning, QR codes should be at least 2cm x 2cm (about 0.8 inches) when printed. Larger sizes scan more easily, especially from a distance. The generated PNG can be resized in image editing software. For high-quality prints, generate at a larger size (384px or 512px) to ensure crisp edges.
Can I customize the colors of my QR code?
Yes, you can customize both the foreground (the dark modules) and background colors. For reliable scanning, maintain high contrast between foreground and background. Dark foreground on light background works best. Avoid using colors that are too similar or low contrast, as this may prevent successful scanning.
