Search for a QR code generator and you will quickly see two words: static and dynamic. Many websites push dynamic codes and a monthly subscription. But for most people, a static QR code is simpler, free and never stops working. This guide explains the difference so you can decide for yourself.
What is a static QR code?
A static QR code stores your content directly inside the pattern of black and white squares. If you make a static code for https://example.com, those exact characters are encoded in the image. A phone reads them and opens the link. No other server is involved.
- It never expires. It works as long as the content inside it is still valid, whether that is a link, a phone number or Wi-Fi details.
- It is private. Nobody records when or where it is scanned.
- It works offline for content such as Wi-Fi, contacts, text and UPI payments.
- It can't be edited. To change the content you make a new code and replace the printed one.
Every code made with the Apna QR generator is static.
What is a dynamic QR code?
A dynamic QR code stores a short link that belongs to the company that made it, something like qr-company.example/ab12. When someone scans it, the phone first goes to that company's server, which records the scan and then redirects to your real website.
- You can change the destination later without reprinting the code.
- You get scan statistics, such as the number of scans, the time and the rough location.
- It depends on the company. If you stop paying, or the company shuts down, the code can stop working or show their own page instead.
- It only works for links. Wi-Fi, contact cards and UPI codes have to be read directly by the phone, so they are always static.
The hidden cost of dynamic codes
The biggest risk of a dynamic code is lock-in. Imagine printing 5,000 product boxes with a dynamic QR code. A year later, the subscription price goes up. You either keep paying or every box in the market points to a dead page. Some free trials even turn codes off when the trial ends. With a static code, there is no one to switch it off.
A dynamic code is also a little slower, because the phone visits an extra server first, and it can fail if that server is down.
How to get the flexibility of dynamic codes for free
If you own a website, you can make a static code that points to a page you control, such as yourshop.in/menu. When your menu changes, update that page. The printed code stays the same. You get most of the benefit of a dynamic code with no monthly fee, and your own website analytics can count visits if you need numbers.
Which one should you choose?
- Wi-Fi password: static (dynamic isn't possible).
- UPI payment code for your shop: static. Your bank or UPI app also gives you one.
- Visiting card or contact details: static.
- Restaurant menu: static, pointing to a menu page or PDF link you can update.
- Product packaging that will be in shops for years: static, pointing to a page on your own website.
- A short marketing campaign where you need scan numbers by location: dynamic can make sense, as long as you understand the subscription.
Common myths
- “Static QR codes expire.” They don't. A static code is just an image of your data. It can only “stop working” if the website, number or details inside it change.
- “Dynamic codes scan better.” A dynamic code often contains a shorter link, which makes the pattern simpler. But a static code for a short link scans just as easily. Size and contrast matter far more. See our printing guide.
- “You need a paid tool for a good-looking code.” Colours, rounded dots, custom eyes and logos all work on static codes, for free.
Bottom line: start with a static code. Choose dynamic only if you really need to change a link after printing and you don't have a website of your own to point to.
