Static QR codes
A static QR code stores your content directly inside the pattern: the full link, WiFi password, contact card or text. Scanning it reads that content straight from the code — no server is involved.
- Never expires. It works as long as the content itself is valid (for example, the website still exists).
- Can't be edited. To change the content, you make a new code and reprint.
- No scan tracking on its own (though you can add UTM tags to links).
- Works offline for WiFi, contacts, text and calendar events.
- Free and private — no account, and nothing is stored.
Dynamic QR codes
A dynamic QR code stores a short redirect link instead of your final content. When someone scans it, the redirect service sends them to the destination you've set in your account.
- Editable — change where it goes at any time, without reprinting.
- Trackable — see how many scans, when, and roughly where.
- Simpler pattern — the short link makes a less dense code that scans easily at small sizes.
- Depends on the service — if the account or service stops, the code stops working.
Side-by-side comparison
| Static | Dynamic | |
|---|---|---|
| Change content after printing | No | Yes |
| Scan analytics | No | Yes |
| Expires | Never | Only if the service or account ends |
| Works without internet | Yes, for WiFi, vCard, text | No |
| Account needed | No | Yes |
Which should you choose?
- Choose static for WiFi, contact cards, UPI payments, WhatsApp chats, and links that won't change (your homepage, Google review link).
- Choose dynamic for anything printed in large quantities or for a long time where the destination might change: menus, packaging, ads, campaigns — or when you want to measure results.
QwikQR's free generators create static codes, and our PDF QR codes let you replace the file behind the code at any time. Register for free to unlock dynamic codes with scan tracking.
Watch out for “free” dynamic codes that expire
Some generators give you a “free” dynamic code that stops working after a trial unless you pay — sometimes after you've printed thousands of copies. Before printing, check what happens to dynamic codes if you don't upgrade. If you just need a code that works forever, use a static one.
