How to Create a Dynamic QR Code
A dynamic QR code uses a redirect URL, so you can change the destination after printing without regenerating the code. This is useful for campaigns where the target URL might change, or when you need detailed scan analytics. This guide explains how dynamic QR codes work and when you need one.
Step-by-Step Guide
Understand How Dynamic QR Codes Work
A dynamic QR code encodes a short redirect URL (like qr.yourdomain.com/abc123) instead of the final destination. When scanned, the redirect server logs the scan and forwards the user to the actual destination. You can change the destination at any time.
Choose a Dynamic QR Code Provider
Options include QR code platforms with redirect services, URL shorteners like Bit.ly, or a custom redirect on your own server. If you use your own domain, you have full control forever.
Create a Redirect URL
Set up a short URL that redirects to your target page. If self-hosting, a simple server redirect (301 or 302) from a short path to your destination URL is all you need.
Generate a QR Code for the Redirect URL
Use the QR generator on this page with the redirect URL. The QR code now points to your redirect, which you can update at any time.
Test and Deploy
Verify the redirect works correctly, then print and distribute the QR code. When you need to change the destination, update the redirect — no reprinting needed.

Pro Tips
- Use your own domain for the redirect to maintain control. Third-party services could shut down or change terms.
- Dynamic QR codes add a redirect step, which adds a fraction of a second to load time. Keep the redirect fast.
- Static QR codes are simpler and work forever with no dependencies. Use dynamic only when you genuinely need to change the destination or track scans.
- If you only need tracking (not URL changes), UTM parameters with Google Analytics on a static QR code may be sufficient.
Frequently Asked Questions
What is the difference between a static and dynamic QR code?+
A static QR code encodes the final destination URL directly. It cannot be changed after printing. A dynamic QR code encodes a redirect URL that forwards to the final destination. You can change the destination by updating the redirect.
Do dynamic QR codes cost money?+
Many dynamic QR code services charge a monthly fee. However, you can create your own dynamic QR code for free by setting up a redirect on your own server or using a free URL shortener.
When should I use a dynamic QR code instead of a static one?+
Use dynamic when: (1) the destination URL will definitely change, (2) you are printing large volumes and cannot afford reprints, or (3) you need detailed scan analytics beyond what UTM parameters provide.
