Every QR code is either static or dynamic. Pick the wrong type and you could be reprinting thousands of flyers when a URL changes. Pick the right type and you will save money, track results, and adapt on the fly. Here is how to decide.
Quick Answer
Static QR codes permanently encode your URL into the pattern. Free, works offline, but cannot be changed after printing.
Dynamic QR codes use a redirect URL you control. Editable anytime, includes scan tracking, but requires an account.
The Core Difference Explained
The distinction comes down to what is encoded in the QR pattern itself:
- Static QR codes encode your full destination URL directly. Scan one and your phone goes straight to
https://yoursite.com/page. The URL is baked into the squares. - Dynamic QR codes encode a short redirect URL like
linkscan.org/s/abc123. When scanned, our server logs the scan then instantly redirects to your actual destination.
This technical difference unlocks (or limits) everything else. Because dynamic codes pass through a server, you can change where they point, see who scanned, and when.
Side-by-Side Comparison
| Feature | Static | Dynamic |
|---|---|---|
| Edit destination after printing | ||
| Track scans and analytics | ||
| Works offline (no server needed) | ||
| Never expires | Account-dependent | |
| No third-party servers | ||
| Requires account | No | Yes (free) |
| QR pattern complexity | Grows with URL length | Always simple |
When to Use Static QR Codes
Static codes are the right choice when your destination will never change and you do not need tracking. They are simpler, faster, and completely independent of any service.
Best Use Cases for Static
WiFi Passwords
Share your network credentials with guests. Works instantly, no internet needed to resolve. See our WiFi QR guide.
Personal Contact Cards
vCard data encoded directly. Hand it out at networking events without worrying about server uptime.
Permanent Links
Your main website, social profiles, or any URL that will not change in the next decade.
Privacy-Sensitive Uses
No tracking, no third-party servers. Your data never leaves your browser during generation.
When to Use Dynamic QR Codes
Dynamic codes shine when flexibility and measurement matter. If you are printing anything at scale or running campaigns, dynamic is almost always the right choice.
Best Use Cases for Dynamic
Marketing Campaigns
Track scan rates, compare placements, measure ROI. Learn more about QR code analytics.
Print Materials
Flyers, posters, brochures. Update URLs without reprinting when campaigns end or links change.
Product Packaging
Point to manuals, warranty registration, or reorder pages. Redirect to successor products when items are discontinued.
Restaurant Menus
Update prices, switch seasonal menus, or add specials without replacing table tents.
Real-World Examples
Here is how the choice plays out in practice:
The Costly Mistake
A retail chain printed 50,000 flyers with a static QR code pointing to /summer-sale. When the sale ended, every flyer led to a 404 page. Reprinting cost over £3,000. A dynamic code would have let them redirect to the autumn collection in seconds.
The Smart Choice
A cafe uses a static QR code for their WiFi password, printed once and framed on the wall. It will work for years with zero maintenance. Meanwhile, their table tent QR codes for the menu are dynamic, letting them update prices weekly without reprinting.
The Data Win
An estate agent uses dynamic codes on property signs. When a house sells, they redirect the code to similar listings. Analytics show them which neighbourhoods generate the most interest, informing where to focus marketing spend.
The Pattern Complexity Factor
Here is something most guides skip: static codes get visually busier as your URL gets longer.
A QR code for https://example.com looks clean. A QR code for https://example.com/campaigns/2025/landing?utm_source=flyer&utm_medium=print&utm_campaign=spring has far more modules (the small squares). More modules means:
- Harder to scan at small sizes or from a distance
- Less room for logos in the centre
- More visual noise on your materials
Dynamic codes avoid this entirely. They always encode a short URL like linkscan.org/s/abc123, keeping the pattern clean regardless of where it actually leads. This is especially valuable when you want to add UTM parameters for tracking.
Do QR Codes Expire?
This is one of the most common questions, and the answer depends on the type:
Static codes never expire. The data is in the pattern itself. Print one today, scan it in 50 years. As long as the destination URL exists, it works.
Dynamic codes depend on the provider. If the redirect service shuts down or deletes your code, it stops working. On LinkScan, your dynamic codes remain active as long as your account exists. We do not delete codes, impose expiration dates, or hold them hostage behind paywalls.
Pricing: What Is Actually Free?
On LinkScan, both types are free to create:
- Static codes: Unlimited, forever free, no account required. Full customisation, no watermarks.
- Dynamic codes: Unlimited free codes with a free account. Includes scan tracking, editable destinations, and project organisation.
The free tier has rate limits (6 dynamic codes per hour, 2 projects, 1 logo QR code). The Advanced tier ($5/month) increases these to 30 codes per hour, 10 projects, unlimited logos, and adds priority support.
Decision Framework
Still unsure? Work through these questions:
Could the destination URL ever change?
Yes = Dynamic. Campaign pages, seasonal content, product links that might be discontinued.
Do you need to know how many people scan it?
Yes = Dynamic. Essential for measuring marketing ROI and comparing placements.
Is this for a high-volume print run?
Yes = Dynamic. The cost of one reprint exceeds years of any QR service. It is insurance.
Is maximum privacy critical?
Yes = Static. No third-party servers involved. Your data never leaves your browser.
Must it work in areas with no internet?
Yes = Static. Dynamic codes need a connection to resolve the redirect (though the user still needs internet to load the destination page either way).
Use Both: A Practical Approach
You do not have to pick one type for everything. Match the tool to the job:
- Static: Office WiFi code on the wall, personal vCard, your unchanging homepage link
- Dynamic: Trade show banners, product packaging, any printed campaign material
Create Your QR Code
Static codes: no account needed. Dynamic codes: free account with unlimited codes.
Get Started FreeFrequently Asked Questions
What is the difference between static and dynamic QR codes?
Static QR codes encode your destination URL directly into the pattern and cannot be changed after creation. Dynamic QR codes use a short redirect URL, allowing you to change the destination, track scans, and view analytics without reprinting the code.
Can I edit a QR code after printing?
Only dynamic QR codes can be edited after printing. Static codes permanently encode the URL into the pattern itself. With a dynamic code, you can change the destination URL at any time through your dashboard.
Do QR codes expire?
Static QR codes never expire as long as the destination URL exists. Dynamic codes depend on the provider - on LinkScan, your dynamic codes remain active as long as your account exists, with no expiration dates.
Which QR code type is better for marketing?
Dynamic QR codes are better for marketing because they provide scan analytics (location, device, time), allow you to update destinations without reprinting, and create cleaner patterns that are easier to scan.
Are dynamic QR codes free?
Yes, LinkScan offers unlimited free dynamic QR codes with scan tracking. The free tier includes up to 6 dynamic codes per hour, 2 projects, and 1 logo QR code. The Advanced tier ($5/month) increases these limits for high-volume users.
Do static QR codes work offline?
Yes, static QR codes work without an internet connection to resolve the redirect. The destination URL is encoded directly in the pattern. However, the user still needs internet to load the actual destination page.
Summary
Static codes are permanent, private, and independent. Dynamic codes are flexible, trackable, and editable. Neither is universally better.
For personal use and truly permanent links, static codes are the sensible default. For marketing, campaigns, and anything printed at scale, dynamic codes save you from the pain of reprinting when things inevitably change.
LinkScan offers both, free. Static codes are generated in your browser with no account. Dynamic codes come with a free account and include unlimited codes with full scan tracking.
