"Static" and "dynamic" QR codes look identical on the surface (the same black-and-white, or colorful, logo-decorated, square) but they work in fundamentally different ways underneath. Understanding the difference matters before you print a few hundred of them.
Static QR codes
A static QR code has your actual data (a URL, a WiFi password, a contact card, plain text, whatever you chose) encoded directly into the pattern of black and white modules. When a phone scans it, it reads that data straight out of the code itself. There is no server in the middle, no account behind it, and nothing that can go offline or get shut down later. It works exactly the same on the day you print it as it does ten years later. This is the kind of QR code this generator creates: build it once, and it's yours for free, forever. See do QR codes expire? for more on exactly what that means in practice.
The tradeoff is that a static code is fixed. If you encoded a link and later need that code to point somewhere else, you have to generate and reprint a new code; you cannot edit what's already baked into the pattern.
Dynamic QR codes
A dynamic QR code instead encodes a short redirect link that belongs to a third-party service (for example, something like qr.example.com/abc123). When scanned, that short link redirects to whatever destination URL you've set for it, and because the redirect target lives on the service's server rather than inside the code, you can change the destination at any time without reprinting anything. Most services offering this also provide scan analytics (how many scans, roughly when and where).
That flexibility is real, but it comes with strings attached: dynamic codes typically require an account with the service that hosts the redirect, and many providers put a scan limit or a time limit on their free tier, after which the code either stops working or needs a paid subscription to keep redirecting. If that service ever shuts down or you stop paying, every dynamic code you've already printed silently breaks, even though the printed square looks unchanged.
Which one should you use?
| Situation | Better fit |
|---|---|
| A link, WiFi network, or contact card that won't change | Static: free, permanent, no account needed |
| Printed once for a one-time event or a single menu run | Static: nothing to maintain afterward |
| You need scan analytics (how many, when) | Dynamic: requires a paid or account-based service |
| The destination link may change after printing thousands of copies | Dynamic: can be worth the subscription at that scale |
The practical middle ground
For most individual and small-business use (menus, WiFi access, event invitations, business cards, product packaging, social links), a static code pointed at a link you control (your own website, a page you can edit anytime) gets you most of the benefit of a dynamic code without a subscription. You cannot change the QR code's destination without reprinting, but you can change what's published at that destination whenever you like, since the code just points to a link, not to fixed content.
