Dynamic vs static QR codes: what’s the difference?
Updated · 2 min read
How a static QR code works
A QR code is just text drawn as a grid of squares. With a static code, that text is your full link — for example https://yourcafe.com/menu-autumn-2026.pdf. A phone camera reads the pattern and opens the link directly. Nothing sits in between.
That makes static codes simple, but it has three consequences:
- They can’t be edited. The link is the pattern. Change one character and you get a completely different code, which means reprinting.
- They can’t be tracked. No server is involved, so nobody can tell you how many people scanned.
- Long links make crowded codes. The more characters you encode, the more squares the code needs, and the harder it is to scan when printed small.
How a dynamic QR code works
A dynamic QR code encodes a short link that belongs to the QR service, such as myqr.fun/r/cafe. When someone scans it, the service records the scan and instantly forwards the visitor to your real destination.
- Edit anytime. Change the destination in your dashboard — the printed code stays exactly the same.
- See every scan. Count scans by day, hour, country and device, so you know which flyer, table or poster works.
- Cleaner codes. A short link needs fewer squares, so the code scans more reliably, even with a logo in the middle.
Side-by-side
| Static | Dynamic | |
|---|---|---|
| Change the link after printing | No | Yes |
| Scan statistics | No | Yes |
| Pattern size | Grows with link length | Small and simple |
| Keeps working if the service stops | Yes | Only while the service and your plan are active |
| Best for | Wi-Fi at home, a one-time personal link | Menus, packaging, flyers, signs, business cards |
Which one should you use?
If the code will be printed for customers, choose dynamic. Menus change, campaigns end, websites move. With a static code every one of those moments means reprinting; with a dynamic code it’s a ten-second edit.
Static codes still make sense for things that will truly never change and where you don’t care about numbers — a Wi-Fi password at home, or a link you share once.
The one thing to check before choosing a dynamic QR service
Because a dynamic code depends on the service’s short link, ask what happens when a trial or plan ends. Some generators quietly switch codes off after a “free” period. With myQR the rules are written up front: the free code works for 7 days, paid codes work while your plan is active, and if you subscribe later the same printed code switches back on — nothing to reprint.
One free QR code for 7 days — no account, no card.
Questions
Can I turn a static QR code into a dynamic one?
No. A static code’s link is fixed in its pattern. You need to create a new dynamic code and replace the printed one — after that, all future changes happen without reprinting.
Do dynamic QR codes scan slower?
The redirect adds a fraction of a second, which people don’t notice. Because the encoded link is short, dynamic codes are often easier for cameras to read.
Are dynamic QR codes free?
Usually not for long, because the service runs the redirect for you. myQR lets you try one free for 7 days; plans start at $5 a month or $48 a year.

Do QR codes expire? The honest answer
QR codes themselves never expire. Static codes work forever; dynamic codes work as long as the service behind them is active. Here is what actually makes a QR code stop working.
