A QR-code pattern has no built-in expiry date. The website, short link, or subscription behind it can stop working.
That distinction matters before you print flyers, packaging, menus, or event materials. A code that works during a free trial may depend on a managed link that is disabled later. A direct code can avoid that dependency, but still lead to a page that moves or disappears.
The useful question is: “What address does this code contain, and what has to remain active for that address to work?”
Static and dynamic QR codes: what changes?
A static QR code stores fixed information in its printed pattern. For a website code, that information is a URL. Every scan reads the same URL.
A dynamic QR code also contains a fixed address, but that address usually belongs to a service that forwards visitors to a destination you manage. You can change the destination in the service while leaving the printed pattern alone.
Question | Direct static code | Code using a managed redirect |
|---|---|---|
What does the printed pattern contain? | The destination URL | A redirect URL |
Can the encoded URL change after printing? | No | No |
Can the page visitors reach change? | Yes, if you control that page or its redirects | Yes, by editing the redirect destination when your plan allows it |
Does generating the code itself require an ongoing subscription? | No | The redirect provider’s terms determine ongoing requirements |
Can you measure openings? | Through the destination’s own analytics, if configured | Through the redirect service’s analytics, if provided |
What must keep working? | The encoded address and destination | The encoded redirect address, service, account entitlement, and destination |
The QR pattern is fixed in both cases. “Dynamic” describes the service behind the address.
Why can a QR code stop working after a trial?
Some generators include managed dynamic codes in their trial. Once that trial ends, the service may stop forwarding visitors until you subscribe.
For example, QR Code Generator’s support documentation says its static codes remain active after the trial, while dynamic codes are deactivated. Other providers have their own terms.
The printed squares have not changed. The forwarding service has changed what it does with the encoded address.
Before choosing a provider, check what happens when the trial ends, a payment fails, or you cancel or downgrade. Look for explicit terms about existing codes, editing rights, usage limits, and deletion. Saving an SVG or PNG file does not remove a dependency on the address encoded inside it.
When a free static QR code is enough
Use a direct static code when you have a stable destination and do not need a separate service to manage it.
For example, a restaurant can encode the address of a menu page on its own website. It can replace the menu content at that same address without changing the code. If the website supports redirects, the restaurant can also manage those itself.
You can create that code with the free toa.ee QR code generator. The entered content stays in your browser, and you can download PNG or SVG without signing up. The generator does not add a trial-controlled redirect when you enter your own destination URL.
The resulting code has no generator-imposed expiration. Your destination still needs to stay available. If you instead enter an expiring short link, temporary download address, or private document URL, the code inherits that address’s limitations.
When an editable short link is worth using
A managed redirect is useful when you expect the destination address to change and want to update it without managing your own server redirects.
Suppose an event poster needs to lead to registration before the event, then to presentation materials afterward. You can print one short-link QR code and update its destination when the time comes.
In toa.ee, create an account-owned short link and download its QR code. Destination editing requires a paid plan. Keep the short-link address unchanged when updating where it leads: that is the address already printed in your code.
You can also use different links for different print placements and compare their activity. If you reuse the same link online, its total openings will include that traffic too; the service cannot assume every opening came from the printed code.
See toa.ee short links and current plan details before deciding whether you need this extra layer.
What happens to toa.ee links if you stop paying?
The answer depends on the type of link and the new plan’s limits.
A direct code from the free generator: there is no toa.ee account subscription to renew. It keeps encoding the same address; that destination must remain available.
An account-owned short link: links within the new plan’s cap remain. Destination editing is a paid feature, so retaining a link on Free does not retain editing access.
Links above the new cap after a downgrade: excess links stay live but uneditable for 30 days, then are deleted. The Free plan currently allows 10 live short links.
An anonymous homepage try-it link: it expires after 24 hours unless claimed through signup. Do not use an unclaimed try-it link in a print run.
These are short-link rules. Digital business cards have separate paid-plan and cancellation rules. Check the terms if your printed code opens a digital business card rather than redirecting to your own website.
No hosted redirect should be treated as a promise that a printed code will work forever. Account status, deletion, abuse restrictions, service availability, and the destination itself still matter.
A seven-point check before you print
Inspect the encoded address. Use a scanner that shows the URL before opening it. Is it your intended domain, an account-owned short link, or a temporary address?
Confirm ownership and billing. Know whose account controls the redirect, who receives renewal notices, and what cancellation does. If an agency makes the code, agree on the handover.
Test the final destination as a visitor. Open it while signed out. A document that works for its owner may require permission for everybody else.
Keep the white border. A regular QR code needs a clear margin four modules wide on each side, as specified by DENSO WAVE. Do not crop it to fit the design.
Use a suitable file and test at actual size. SVG stays sharp when scaled. Test a physical proof at the intended viewing distance, with more than one phone, before ordering the full run.
Test a destination change if you need editing. Change it once, scan again, and confirm the printed short-link address stayed the same.
Print a readable fallback address. Give people another way to reach you if their camera cannot read the code.
For a long-running campaign, keep the encoded URL, destination, account owner, and renewal details with the original artwork. Recheck the live code periodically.
If your printed QR code has already stopped working
First separate a scanning problem from a link problem.
If the phone cannot read the pattern, check print quality, contrast, size, damage, and whether the clear border was removed.
If it reads an address but that address fails, copy the address and inspect the dependency. A provider’s disabled-code page points to a service or account issue. A missing website page or restricted document points to the destination.
If you control the encoded domain, you may be able to restore that address or add a redirect. If a third-party redirect is disabled, check whether the account owner can reactivate it or ask the provider for help.
You cannot change a third party’s encoded address just by uploading the QR image to another generator. When the original address cannot be restored or controlled, the practical remedy is usually replacement artwork, a sticker with a new code, or a reprint.
Questions customers ask
Can I change a QR code after printing it?
You cannot change the URL encoded in the printed pattern. You can change where that URL leads if you control its website or have editing access to its redirect service.
Do I need a subscription for every QR code?
No. A direct static code can link to your own website without a QR-service subscription. Managed destination editing and analytics may require an account or paid plan.
Will downloading a QR code make it permanent?
Downloading preserves the image. It does not preserve the destination, domain, redirect service, or account entitlements behind the image.
Can I make a QR code without sharing the entered URL with toa.ee?
The free generator creates the code in your browser; the content you enter stays there. That is different from creating a managed short link, which requires toa.ee to store its destination so it can redirect visitors.
Choose the code around the job
For a stable address you control, make a free static QR code. If you need destination changes and link statistics, explore managed toa.ee short links and check the plan terms before printing.
