Static QR codes: simple, free, permanent
A static QR code encodes your information directly into the pattern itself. Scan it, and the data — a URL, some text, a Wi-Fi password, a phone number — is read straight off the code. Nothing sits in between.
What that means in practice:
✅ Free, forever. There's no server to maintain, so good tools give them away with no limits. (EUQR's static codes are free with no signup and no scan caps.)
✅ They never break. Because the data is in the code, it works even if the company that generated it disappears.
✅ No tracking, total privacy. Nothing routes through a server, so there's nothing to log.
❌ You can't change them. The destination is baked in. Print it, and it's final.
❌ No analytics. No redirect means no scan data.
Static is perfect for: Wi-Fi access codes, a fixed phone number or email, a vCard/business card, a permanent link that will never change, or any one-off where you don't need data.
Dynamic QR codes: editable, trackable, flexible
A dynamic QR code encodes a short link that points to a redirect server. The code says "go here," and the server decides where "here" is — which you can change at any time.
What that means in practice:
✅ Editable after printing. Change the destination whenever you like — the printed code stays the same. Fix a typo, swap a campaign, redirect a discontinued product.
✅ Trackable. Because each scan passes through the server, you get analytics: scan counts, rough location, device, time.
✅ Shorter, cleaner codes. A short link encodes into a simpler, more scannable pattern than a long URL.
❌ They depend on the provider. The redirect server has to keep running. This is the catch most people don't see coming (more on that below).
❌ Usually paid. Maintaining the redirect and analytics costs the provider money, so dynamic codes sit behind a subscription.
Dynamic is perfect for: restaurant menus, marketing campaigns, product packaging, anything you'll print in bulk before the destination is final, and anything where you want to measure performance.
The catch with dynamic codes — and how to avoid it
Here's the part the comparison charts skip: with most providers, the day you stop paying, your dynamic codes are switched off — and every poster, menu, and package you printed now leads to a dead 404. QR Tiger, for example, deactivates dynamic codes on cancellation with no documented grace period. For a business with fifty printed table-tents, that's fifty broken codes overnight.
This is worth designing around. Two ways to protect yourself:
Use static codes for anything that genuinely never needs to change (so it can never break).
For dynamic codes, choose a provider with a safety net. EUQR falls back to a branded Recovery Page for 90 days after cancellation, so a paused campaign or an expired card never kills your printed codes — you get time to reprint or migrate.
Static vs dynamic: a 10-second decision guide
Ask yourself… | Use static | Use dynamic |
|---|---|---|
Will the destination ever change? | No → static | Yes → dynamic |
Do I need scan analytics? | No → static | Yes → dynamic |
Am I printing in bulk before the URL is final? | — | Yes → dynamic |
Is it a Wi-Fi code, vCard, or fixed contact detail? | Yes → static | — |
Do I want it free and permanent? | Yes → static | — |
Rule of thumb: if it's fixed and forever, go static (and free). If you'll edit it, measure it, or print it before you're sure, go dynamic — and pick a provider that won't hold your codes hostage.
Make either, in seconds
EUQR generates both: static codes free forever (no signup, no scan caps, no watermark) and dynamic codes from €0.99/mo with privacy-first analytics, unlimited scans, and the Recovery Page. Toggle between them in the generator and download as PNG, SVG, or WebP.
