Static vs Dynamic QR Codes: What's the Difference?

Every QR code is either static or dynamic. Choosing wrong can mean a wasted print run — or a code you can never fix. Here's the difference in plain terms.

What is a static QR code?

A static QR code encodes your destination URL directly. When someone scans it, their phone reads the URL right off the pattern and goes there. Nothing sits in between.

• Pros: free forever, works offline, no dependency on any service.
• Cons: the destination can never change. The URL is baked into the pixels.

Static codes are perfect for things that never change: a link to your homepage, a one-time payment address, a WiFi password you don't rotate.

What is a dynamic QR code?

A dynamic QR code encodes a short redirect URL that you own — for example qrmkr.io/r/abc123. When scanned, that URL redirects to your real destination. Because the redirect lives on a server, you can change where it points at any time — even after the code is printed.

• Pros: edit the destination anytime, track every scan, A/B test, retarget.
• Cons: depends on the redirect service staying online (which is exactly why it's a subscription — your codes stay alive as long as you're a customer).

Which should you use?

Use a static code when the destination will truly never change and you don't need scan data. Use a dynamic code for anything printed at scale, anything tied to a campaign, or anything where you want to know how many people scanned.

Rule of thumb: if you're printing it, make it dynamic. Reprinting is expensive; editing a link is free.

Why dynamic codes use a temporary redirect

Good dynamic QR services use a temporary redirect (HTTP 302/307), not a permanent one (301). A permanent redirect gets cached by browsers and would prevent you from ever changing the destination — defeating the entire purpose. QRmaker uses temporary redirects so your codes stay editable for life.
