Static vs. Dynamic QR Codes
Most people only need a static QR code. Dynamic codes can be useful, but they add complexity, cost, and a dependency on a third-party redirect service that can disappear — or start charging. Here's what you actually need to know.
Static QR codes
A static QR code stores the final destination directly inside the code — like a full URL baked into the pattern. There's no middleman, no redirect, no server involved.
- What it is: The destination URL (or text, contact, WiFi info) is stored directly in the QR code itself.
- Best for: Permanent links — menus, product pages, profiles, PDFs, business cards, anything that won't change.
- Pros: Simple, reliable, no third-party dependency, works forever.
- Cons: If you need to change the destination later, you have to reprint.
✅ This is what MakeQRCode.app generates. You download the QR image and own it completely — no account, no subscription, no redirect link that could break.
Dynamic QR codes
A dynamic QR code stores a short redirect URL (like qr.example.com/abc123). When someone scans it, they're sent through that redirect to your actual destination. The redirect can be changed without reprinting the QR code.
- What it is: The QR code stores a short redirect URL. You can update where it points later.
- Best for: Marketing campaigns where destinations change, or when scan analytics matter.
- Pros: Editable destination without reprinting, possible scan analytics.
- Cons: Depends on the redirect service staying online and solvent. If they shut down or you stop paying, every printed QR code breaks instantly.
⚠️ The hidden risk: Several "free" dynamic QR services have shut down or moved behind paywalls — breaking thousands of printed codes overnight. Your QR code is only as reliable as the company behind the redirect.
Side-by-side comparison
| Static | Dynamic | |
|---|---|---|
| Where data lives | Inside the QR code | On a redirect server |
| Can change destination? | No (must reprint) | Yes |
| Third-party dependency | None | Yes — redirect service |
| Scan analytics | No | Sometimes (paid) |
| Cost | Free forever | Often free then paid |
| Reliability | Works as long as your link works | Depends on redirect service |
| Privacy | No tracking by default | Scans logged by provider |
Which should you choose?
For the vast majority of uses — menus, business cards, flyers, product packaging, signage — static is the right choice. It's simpler, more reliable, and doesn't depend on anyone else's infrastructure.
Dynamic makes sense when you genuinely need to swap destinations without reprinting (like a seasonal campaign poster), or when scan analytics are critical to your business. Just choose a trustworthy provider and have a plan if they change their pricing.
Do static QR codes expire?
No. Static codes don't expire. The link can "die" only if the destination page is removed or the URL changes — not because of anything in the QR code itself.
Can I convert a static QR to dynamic later?
No — they're fundamentally different. If you need dynamic, you need to generate a new QR code through a dynamic service and reprint.
Why do some "free" QR services charge for dynamic codes?
Because dynamic codes require them to run redirect servers indefinitely. That costs money, so many services start free and eventually move to a paid model — or shut down entirely.
