Dynamic vs static QR code: what's the difference?

A static QR code has its destination URL permanently encoded into the QR pattern. Once generated, it cannot be changed — if the URL breaks or needs updating, you must generate a new code and reprint all materials. A dynamic QR code stores a short redirect link in the pattern; the actual destination URL is stored on a server and can be updated at any time without changing the QR code image. Dynamic QR codes also include built-in scan tracking (count, location, device, timestamp), which static QR codes do not provide. For any use case involving physical print or ongoing campaigns, dynamic QR codes are the more practical and powerful choice.

For the vast majority of use cases, yes — dynamic QR codes are significantly more useful than static ones. They are editable after printing, which protects you from the costly mistake of printing thousands of materials with a URL that later needs to change. They include built-in scan tracking, which gives you data on how many people scanned, from where, and on what device. On qrcode.ing, dynamic QR codes are free, so there is no cost trade-off to consider. The only scenario where static might be marginally simpler is a one-time, permanent destination (such as a Wi-Fi password or archived document URL) where you are certain the URL will never change and tracking is unnecessary.

No — it is not possible to convert an existing static QR code into a dynamic one. The QR pattern for a static code directly encodes the destination URL, so changing the destination requires generating an entirely new code with a different pattern. What you can do is create a new dynamic QR code on qrcode.ing and use it in place of your existing static code whenever materials are reprinted or refreshed. Going forward, creating every new QR code as dynamic eliminates the conversion problem entirely — you will always have the flexibility to update the destination without reprinting.

Yes. On qrcode.ing, dynamic QR codes with built-in scan tracking are available at no cost. You can generate a dynamic QR code, edit its destination URL at any time, and view scan analytics — all for free. Some advanced analytics features (such as extended history and CSV exports) are available on paid plans, but the core dynamic QR functionality including scan tracking is free. Many people assume dynamic QR codes require a paid subscription, but qrcode.ing makes the core features accessible without a paywall.

Static QR codes do not expire on their own — the URL is encoded directly into the pattern and will continue to work as long as the destination URL remains active. However, if the destination URL goes offline, is deleted, or is redirected to a different location, the static QR code will appear broken to anyone who scans it. This is precisely the risk that dynamic QR codes eliminate: because the destination is stored on a server (not in the pattern), you can update it if the original URL goes down. Static QR codes are as permanent as the URL they point to — and URLs are less permanent than most people assume.

Not natively. A static QR code does not include any tracking mechanism — scans go directly to the destination URL with no intermediary logging. You can partially work around this by adding UTM parameters to the destination URL, which allows your web analytics platform to attribute traffic from the QR code. However, this only captures users who complete the full page load and are tracked by your analytics platform — it misses users who scan but do not load the page, and it provides no device or location data at the QR level. Dynamic QR codes on qrcode.ing log every scan at the server level before the redirect, giving you accurate scan counts, location data, and device breakdowns that UTM parameters alone cannot provide.

The easiest way to tell is to look at what the QR code encodes. You can scan your own QR code with a standard camera app and read the raw content before it redirects. A static QR code will show your full destination URL directly (e.g., https://yourdomain.com/page). A dynamic QR code will show a short redirect URL (e.g., a qrcode.ing short link) that then redirects to your destination. If you created the QR code on qrcode.ing, all codes are dynamic by default — you can confirm this in your qrcode.ing dashboard where you can see and edit the destination URL for each code.

If you delete a dynamic QR code from your qrcode.ing account, the short redirect link embedded in the QR pattern will stop working — scans will no longer be redirected to a destination and users will see an error. This means any physical materials that still have that QR code printed on them will produce a broken experience for anyone who scans them. Before deleting a dynamic QR code, make sure all physical materials carrying it have been retired or replaced. If you want to stop a campaign but keep the code functional, a better approach is to update the destination URL to a neutral landing page rather than deleting the code entirely.
