Static vs Dynamic QR Codes: What's the Difference?
QR codes come in two fundamental types: static and dynamic. Choosing the right one affects whether you can edit your link later, whether you can track scans, and how much you pay. This guide explains the difference in plain terms.
What is a static QR code?
A static QR code encodes your destination — a URL, text, Wi-Fi credentials, or contact details — directly into the QR pattern. Once printed, the destination is fixed: you cannot change it, and because nothing passes through a server, you cannot track scans. Static codes are ideal for information that never changes, such as a Wi-Fi password or a vCard. On hrefs.eu they are free forever, with unlimited scans and no expiry.
What is a dynamic QR code?
A dynamic QR code encodes a short redirect link instead of your final destination. When someone scans it, they are routed through that short link to wherever you currently point it. Because the redirect runs through a server, you can change the destination at any time — even after printing — and record analytics such as scan count, approximate location, and device type. Dynamic codes are the right choice for marketing campaigns, packaging, posters, and menus.
Which should you use?
Use a static QR code for fixed information you will never need to edit or measure. Use a dynamic QR code whenever you might want to update the destination later, or whenever you want to know how your code is performing. On hrefs.eu, static codes are free and dynamic codes cost just €1.99/month with unlimited scans, so you can choose based on need rather than budget.
Frequently asked questions
Can I convert a static QR code into a dynamic one?
No. Because a static code embeds the destination directly, you must create a new dynamic code if you need editability or analytics. It is best to choose dynamic from the start if there is any chance you will want to change the link.
Do dynamic QR codes cost more to scan?
On hrefs.eu there are no per-scan fees on any plan. You pay a flat €1.99/month for dynamic codes regardless of how many scans they receive.
