## Frequently Asked Questions

**Q: What is a QR code?**
A: A QR code (Quick Response code) is a type of barcode that stores information like website links, text, or contact details. When scanned with a smartphone camera or QR code reader, it quickly redirects users to the stored content.

**Q: What are dynamic QR codes?**
A: Dynamic QR codes allow you to change the destination URL or content after creation, while static QR codes are fixed. Dynamic codes are ideal for marketing and analytics tracking.

**Q: Can I edit a QR code after printing?**
A: Yes! Dynamic QR codes let you update the URL or content anytime without changing the printed QR code itself.

**Q: Is QRelix free?**
A: Yes — QRelix is free forever, with no credit card required. Your QR codes never stop working. For the first 7 days, you have full access to the analytics dashboard. After 7 days, scans show a brief QRelix-branded screen before forwarding visitors to your destination, and the analytics dashboard for that QR code moves behind an upgrade. QRelix Pro ($5.99/month) removes the branded screen and restores full analytics indefinitely.

A: QRelix generates QR codes in 300 DPI SVG format, which is print-ready and scales to any size without quality loss.
