❓ Frequently Asked Questions

Q: Can I add a logo to my QR code?

A: Currently, you can add text inside the QR code. For logos, you would need specialized QR code software. However, our high error correction allows for some customization in the center.

Q: What's the maximum data size for a QR code?

A: QR codes can store up to 4,296 alphanumeric characters. However, smaller data sizes scan faster and more reliably.

Q: Will my QR code expire?

A: No! QR codes generated with our tool never expire. However, if you use a URL shortener, that link might expire based on the service's policy.

Q: Can I edit a QR code after creating it?

A: No, QR codes are static. To change the content, you need to generate a new QR code. For dynamic content, consider using a URL that points to updatable content.

Q: What size should I print my QR code?

A: Minimum 2cm x 2cm (0.8" x 0.8"). For outdoor or distant scanning, use larger sizes (10cm+ recommended).

Q: Why won't my QR code scan?

A: Common issues:

• Low contrast between QR code and background
• QR code too small
• Poor lighting
• Damaged or wrinkled surface
• Camera focus issues

Q: Can I use colored QR codes?

A: Yes! Just ensure high contrast. Dark colors on light backgrounds work best. Avoid light colors like yellow or light gray.

Q: Are QR codes secure?

A: QR codes themselves are just data containers. Security depends on the content. Always verify the source before scanning unknown QR codes.

Q: Can I track QR code scans?

A: Our generator creates static QR codes without tracking. For analytics, use a URL shortener with tracking (like Bitly) in your QR code.
