Static vs Dynamic QR Codes
Definition: Static QR codes encode data permanently, while dynamic QR codes use a redirect that can be changed after printing.
Static QR codes embed the final content directly into the code pattern. Once created, they cannot be changed. Dynamic QR codes instead encode a short redirect URL — the final destination is managed through a dashboard and can be updated anytime. Dynamic codes also enable scan tracking, A/B testing, and expiration dates, but typically require a subscription service.
Key points
- Static: free, permanent, no tracking
- Dynamic: editable, trackable, requires service
- Static codes are denser (more data = more modules)
- Dynamic codes are simpler (short redirect URL)
- Use static for permanent content, dynamic for campaigns
Frequently asked questions
Are static QR codes free?
Yes! Static QR codes are completely free to create and use. They encode data directly and don't require any ongoing service or subscription.
Can I change a static QR code after printing?
No — static QR codes cannot be changed after creation. If you need to update the destination, you'll need to create and reprint a new code.
When should I use dynamic QR codes?
Use dynamic codes for marketing campaigns, temporary promotions, A/B testing, or anywhere you might need to update the destination without reprinting.
