It depends on the tool and the code type. Static codes from any generator never expire, because the destination lives inside the pattern. Dynamic codes are different: they route through the generator's servers, so the company can switch them off when a free trial or subscription ends. The generator does not expire codes. Its billing does.
The rest covers which codes a generator can deactivate, why free tools do it, and how to make one that no clock can touch. For the version across every tool, see do QR codes expire.
Do QR codes from a QR code generator expire?
Static ones do not. Dynamic ones can. A static QR code stores the destination inside the black-and-white pattern. Your phone decodes it locally, with no server in the loop. The generator that made it has no way to reach back and switch it off. Delete the account, close the tab, let the company fold — the printed code keeps working.
A dynamic QR code is the opposite. The pattern holds a short redirect URL on the generator's domain, and each scan passes through their servers to a destination you can edit later. That indirection is the feature. It is also the leash. When nothing is paying to keep the redirect alive, the code stops resolving. The generator is the party that ends it.
So the honest answer has two halves. The generator cannot expire a static code. It can expire a dynamic one, and whether it does comes down to the plan you are on.
Which QR code generators expire codes, and which don't?
The split is not really between brands. It is between static and dynamic, and between generators that hold dynamic codes hostage and those that don't. The table shows how the two code types behave, whatever the tool.
| Code type | Who controls it | Can the generator expire it? |
|---|---|---|
| Static | The printed pattern itself | No. No server is involved. |
| Dynamic (no-hostage tool) | You, via the redirect | Only editing and analytics lapse. The redirect keeps working. |
| Dynamic (free-trial tool) | The generator's billing | Yes. Scans are deactivated or diverted when payment stops. |
Why do free QR code generators deactivate codes?
Because the deactivation is the sales pitch. Many generators rank first for "free", let you make a dynamic code, and let you print it. The trial then ends, the code goes dark, and the only way to revive a flyer already in the wild is to pay. We named the mechanic the free trial trap.
The timing is the tell. A code that fails the week after a print run, right as a trial lapses, did not break. It was switched off on schedule. Some tools go further and point the dead code at their own upgrade page, so a scanner sees a sales notice where your menu should be.
None of this touches static codes. A static code has no account behind it to lapse. That is why the safest code a free generator can give you is often the plain one it markets least.
How can I tell if my generator's codes will expire?
Check the code type first, then the policy. Two questions settle it before you print anything.
- Did you make a static or a dynamic code? If the tool never asked you to sign in and the download is a fixed image, it is static, and it will not expire. If you can edit the destination after downloading, it is dynamic, and it depends on a live plan.
- What does the tool promise when payment stops? Read the pricing and support pages, not the homepage banner. A generator worth trusting states in writing that dynamic codes keep redirecting after a plan ends. Silence on that point usually means the code is a hostage.
- Is there a countdown you did not choose? A "7-day trial" on a dynamic code is a deactivation date. Scan-test the printed code, then diarize the trial end so a live flyer does not go dark unnoticed.
Do static codes from a generator ever expire?
No. This is true of every static code from every generator, ours included. A static code is a fixed image of a pattern, and an image has no off switch. The destination is baked in at download. QR codes have worked this way since Denso Wave published the format in 1994.
The trade-off is that a static code cannot be edited or tracked. The URL is fixed the moment you download it. To re-point a printed code or count scans, you need a dynamic code, and then the question becomes who holds the leash. See static vs dynamic for the full comparison, and how to redirect a QR code for what the dynamic layer buys you.
How do I make a QR code from a generator that never expires?
Separate the two needs first. If you only need a code that lasts, make a static one. Qranite's free generator computes the pattern in your browser, so your data never reaches our servers. We could not expire your code if we tried, because we never had it. No signup, no watermark, SVG for print and PNG up to 4096px.
If you also need to re-point a printed code or read scans, that takes a dynamic code, and the difference is the policy behind it. Qranite's dynamic codes carry a written no-hostage rule: stop paying and your printed codes keep redirecting. You lose editing and analytics beyond the free tier, never the redirect itself. A free account includes 2 dynamic codes; Pro is $9/mo or $72/yr for 50; Lifetime is $79 once for 10.
The contrast is the whole point. A free-trial generator expires the dynamic code you printed and bills you to bring it back. Qranite keeps it pointing where you set it, because a printed code in someone's hand should not depend on your next invoice. If a permanent code is all you want, the never-expires generator is the short version.
