Static vs Dynamic QR Codes: Which Should You Use?
Not all QR codes are the same. Static codes are permanent and free. Dynamic codes can be edited after printing and track scans. Here is how to choose.
What is a static QR code?
A static QR code encodes data directly into the image pattern. Once generated, the content cannot be changed. The code works independently — no server, no internet connection needed for the QR code itself to function. Static codes never expire and are completely free to create.
Tips
- Static codes are ideal for Wi-Fi passwords, contact cards, and permanent URLs
- The more data you encode, the more complex (and harder to scan) the pattern becomes
What is a dynamic QR code?
A dynamic QR code contains a short redirect URL instead of the actual destination. When scanned, the user is redirected through a server to the final destination. This means you can change where the code points without reprinting it. Dynamic codes also enable scan analytics — location, device, time, and total scan count.
Tips
- Dynamic codes have simpler patterns because they only encode a short URL
- They require an active account to keep the redirect working
Key differences at a glance
Static codes: free, permanent, no tracking, cannot be edited. Dynamic codes: editable destination, scan analytics, shorter redirect URL (simpler pattern), require an active account. Static codes are best for permanent content. Dynamic codes are best when you need flexibility or analytics.
When to use static QR codes
Use static codes for Wi-Fi passwords, vCard contact information, email addresses, phone numbers, plain text, and any URL you are confident will not change. Static codes are also the right choice when you need the QR code to work offline or without depending on any service.
When to use dynamic QR codes
Use dynamic codes for restaurant menus (URLs change seasonally), marketing campaigns (track effectiveness), business cards (update your portfolio URL), event materials (change event details), and any printed material where the destination might need updating after printing.
Frequently Asked Questions
Can I convert a static QR code to dynamic?
No. Once a static code is printed, its content is permanent. You would need to create a new dynamic code and reprint.
Do dynamic QR codes cost money?
Most platforms offer a limited number of free dynamic codes. EZQR gives you 3 free dynamic codes. Paid plans offer 25 or 100.
What happens to dynamic codes if I cancel my subscription?
On EZQR, dynamic codes stay active for 30 days after cancellation so you have time to migrate. Static codes work forever regardless.
Which type produces a simpler, easier-to-scan pattern?
Dynamic QR codes produce simpler patterns because they only encode a short redirect URL, not the full destination content.
