  • Add Error Correction: Our generator includes error correction, so codes work even if slightly damaged
  • Maintain Contrast: Ensure good contrast between QR code and background - black on white works best
  • Keep It Simple: Shorter URLs create simpler QR codes that scan faster and more reliably
  • Update Regularly: If using dynamic content, update QR codes when URLs change
  • Track Performance: Use URL shorteners with analytics to track QR code scans and engagement

Frequently Asked Questions

Do I need to download an app to scan QR codes?

No! Modern smartphones (iPhone iOS 11+ and Android 8+) have built-in QR code scanners in their camera apps. Just open your camera and point it at the QR code. No additional apps required.

Can I customize the colors of my QR code?

While our free generator creates standard black and white QR codes, colored QR codes are possible but require careful design to maintain scannability. Black on white provides the best scanning reliability across all devices.

How long do QR codes last?

QR codes themselves don't expire, but the content they link to might. If your QR code points to a URL, ensure that URL remains active. Static QR codes (text, WiFi) work indefinitely as long as the information doesn't change.

Can QR codes be tracked?

Standard QR codes don't include tracking. However, if your QR code links to a URL, you can use URL shorteners with analytics (like Bitly) to track scans, location, device type, and timing.

What's the difference between QR codes and barcodes?

Traditional barcodes are one-dimensional and store limited data (usually 12-13 digits). QR codes are two-dimensional, storing much more information (up to 4,296 characters) and can include URLs, text, and other data types.

Are QR codes secure?

QR codes themselves are just encoded data - they're neither secure nor insecure. Always verify the destination before scanning QR codes from unknown sources. For sensitive information, use encrypted connections (HTTPS) and verify the source.

Can I edit a QR code after creating it?

You cannot edit an existing QR code. If you need to change the content, generate a new QR code with the updated information. This is why it's important to test QR codes before printing or sharing widely.
