Static vs dynamic QR codes
Both look identical when you scan them, but under the hood they work very differently — and choosing the wrong one can mean reprinting everything. Here's the difference in plain language.
What is a static QR code?
A static QR code has the information encoded directly into the pattern. Once it's generated, it can't be changed — the URL, text or WiFi details are locked in forever.
Static codes are fine for things that never change, like connecting to a WiFi network or encoding a plain piece of text. But you can't edit them and you can't see how many times they're scanned.
What is a dynamic QR code?
A dynamic QR code encodes a short redirect URL instead of the final content. When someone scans it, they're sent to whatever destination you've set — and you can change that destination anytime.
Because every scan passes through that short URL, dynamic codes also let you track scans in real time: how many, when, what device and which country.
Which one should you use?
Use a dynamic QR code for anything you print or can't easily reprint — flyers, packaging, business cards, menus, signage. You can fix typos, change campaigns and update links without touching the printed code.
Use a static code only for fixed, one-off needs where you'll never need analytics or edits. For most real-world uses, dynamic wins.
A note on expiration
Some 'free' generators create dynamic codes that stop working after a trial. With Nexxo QR, your dynamic QR codes never expire — they keep redirecting forever, even on the free plan.
Frequently asked questions
Can a static QR code be edited?⌄
No. Static codes have the data baked into the pattern, so the only way to change them is to generate and reprint a new code.
Do dynamic QR codes cost money?⌄
Not necessarily. You can create dynamic QR codes for free here, and they never expire. Paid plans add unlimited codes and detailed analytics.
Can people tell if a QR code is static or dynamic?⌄
No. They look and scan the same — the difference is only in how the data is stored and whether you can edit and track it.
