QR Code Best Practices for Maximum Scannability
Use high contrast: Dark patterns on light backgrounds work best. Avoid light colors on light backgrounds or vice versa—it reduces scannability.
Maintain minimum size: Print QR codes at least 2cm × 2cm (0.8in × 0.8in) for reliable scanning. Smaller codes may not scan from a distance.
Add clear instructions: Include text like "Scan to Connect to WiFi" or "Scan for Menu" so users know what to expect.
Leave quiet space: Maintain a clear border around your QR code (at least 4 modules wide) to ensure reliable scanning in cluttered environments.
Test before printing: Always scan your QR code on multiple devices (iOS and Android) before mass printing to ensure it works correctly.
Consider placement: Position QR codes at eye level (120-150cm) and ensure adequate lighting for scanning. Avoid curved surfaces when possible.
Use SVG for printing: Download SVG format for professional printing to maintain quality at any size. PNG works great for digital use.
Frequently Asked Questions
Q: Is your QR code generator really free?
A: Yes, completely free! Create unlimited QR codes with no hidden costs, no watermarks, no signup required, and no expiration. All QR codes work forever.
Q: Do QR codes expire?
A: No, QR codes themselves never expire. The data is encoded directly into the QR code image. However, if the QR code links to a URL, that URL could change or stop working over time.
Q: Are my QR codes private and secure?
A: Absolutely! All QR code generation happens locally in your browser using client-side JavaScript. Your data never leaves your device or gets uploaded to our servers. It's 100% private.
Q: Can I customize QR code colors?
A: Yes! You can change both foreground (pattern) and background colors. However, maintain high contrast (dark on light or light on dark) to ensure reliable scanning. Avoid low-contrast combinations.
Q: What's the difference between PNG and SVG downloads?
A: PNG is a raster image format—great for web use and standard printing. SVG is a vector format—scales infinitely without quality loss, perfect for large format printing, signage, or professional design work.
Q: How do I create a WiFi QR code?
A: Select "WiFi" as the QR type, enter your network name (SSID), password, and encryption type (WPA/WPA2, WEP, or None). When scanned, users can connect to your WiFi automatically without typing credentials.
Q: Can I track QR code scans?
A: QR codes themselves don't track scans. However, if your QR code links to a URL, you can use URL shorteners with analytics (like Bitly) or add tracking parameters to monitor scans through your website analytics.
