How to Update a QR Code Without Reprinting
You printed 1,000 brochures with a QR code. Six months later, you change your website, and the code now points to a 404. A dynamic code fixes that without a reprint, if it was made the right way.
You printed 1,000 brochures with a QR code. Six months later you change your website. The code now points to a 404 error and the brochures are worthless. To fix it you can either reprint, which is expensive, or find a way to change where the code goes without changing the pattern.
That is what a dynamic QR code is for. Instead of your destination, the printed pattern holds a short link. The short link redirects to your real page, and you can change that page whenever you like. The pattern never changes.
Most people only learn this after a printed code breaks. Below is how it works on this site, the exact steps to update a code, and a quick check that tells you whether a code you already printed is dynamic at all. That last part matters, because a code only behaves dynamically if the image you printed contains the short link.
How do I update a QR code without reprinting it?
Make the code dynamic, print the image from that screen, and when something changes open My QR Codes in the same browser, click Edit on that code, paste the new URL and save. The printed pattern holds a short link, so only the page behind it changes, and it changes immediately. Static codes cannot be updated, because their destination is written into the pattern.
How a Dynamic QR Code Works
A static QR code is a business card with your address printed on it. If you move, the card is wrong. A dynamic code is a card that says "call this number for my address". You change the address behind the number, and the card stays the same.
Concretely: when you click Make Dynamic, the site stores your destination and gives the code a short link in the form trulyfreeqr.link/r/ plus eight characters. That short link is what the QR image encodes. When someone scans the code, the redirect server looks up the short link, finds your destination, and sends the visitor there with a standard redirect. It also records the scan, which is where the analytics come from.
To update the code you change the stored destination. The short link in the printed pattern does not change, so every printed copy follows the update. This works for any printed material: brochures, business cards, packaging, yard signs, menu cards, tickets.
Only URL and PDF codes can be dynamic. WiFi, vCard, email and text codes hold their data inside the pattern, so they are static by nature and cannot be re-pointed.
Step by Step: Change the Destination
Here is the full flow, from the first click to testing the printed code.
Check What Your Printed Code Really Contains
Do this before you print a large run, and for any code you printed a while ago. Open your phone camera, point it at the code, and look at the link it offers to open, without tapping it. The iPhone camera shows the link before it opens anything, and on Android the camera app or Google Lens does the same. Any scanner app that shows the text before opening it works too.
If the link starts with trulyfreeqr.link/r/, the code is dynamic and you can change its destination. If it shows your own address directly, the code is static: it will keep opening that address forever, whatever you do in My QR Codes.
One thing worth knowing: before the October 2026 update, the PNG and SVG downloaded from the main generator screen contained the destination directly, even after you clicked Make Dynamic. Only the PNG downloaded from My QR Codes carried the short link. The generator now puts the short link in the image as soon as you make a code dynamic. If you downloaded a code earlier from the generator screen, scan it as described above. If it turns out to be static, open My QR Codes, download the PNG of that code from there, and use that file for future prints.
It also helps with scanning. A short link is a short payload, so the code has fewer, larger modules than a code holding a long URL, and it stays readable when printed small.
Who Can Edit a Code, and What If You Lose Access
There are no accounts, no passwords and no edit links. The list in My QR Codes, and the key that lets you edit each code, are stored in the browser where you made the code. That keeps the service free of sign-ups, and it has one consequence: edits only work from that browser on that device.
If you clear the site data, switch to a new computer, or use a different browser, you can no longer edit those codes. The printed codes are not affected: they keep redirecting to the last destination they had. So the practical advice is to create and edit your important codes from one browser you control, avoid clearing its site data, and keep your own list of short links with what each one points to and where it is printed.
For a long-lived print run, there is a simple safeguard: point the code at a page on your own site and change the content of that page when things move. Then even a lost browser does not strand you.
What an Update Can and Cannot Do
Every time you save a new destination, Safe-Scan runs again: only https addresses are accepted, URL shorteners and high-risk address patterns are rejected, and the address is looked up on Google Safe Browsing. If the new destination fails, the update is refused and the old one stays in place. These checks run when you save an edit, not on every scan.
Edits take effect immediately. There is no schedule, no approval step and no history of past destinations: only the current destination is stored. Editing is free and the code does not expire. The honest tradeoff is that a dynamic code goes through this service, so it works only while the service is online; a static code has no such dependency but cannot be changed.
