Free dynamic QR code generator
Create a QR code you can edit after printing. Change the destination from your dashboard — the code in print stays the same. No scan limits. No expiry. No watermarks.
Static vs dynamic QR codes
A static QR code has the destination baked in. If the URL changes, the code is broken — you have to reprint.
A dynamic QR code points to a short redirect. You control where that redirect goes from a dashboard. The physical code never changes — only its destination does.
Encodes the URL directly. Fast to make. Can never be updated after printing. Broken the moment the destination changes.
Encodes a redirect URL. Update the destination anytime from your dashboard. The printed code keeps working forever.
How it works
Paste your URL
Enter the destination you want the code to point to. This can be a menu, a product page, a PDF, a booking link — anything with a URL.
Download and print
Get a high-resolution PNG. Print it on whatever you need — menus, cards, signage, packaging.
Edit from your dashboard
When the destination changes, log in and update the redirect. The printed code keeps working — no reprinting.
What's included free
Update the destination URL from your dashboard at any time. The physical code stays the same — only where it redirects changes.
Scanta codes redirect indefinitely. There's no trial timer or expiry date quietly counting down.
Unlimited scans on every plan. Whether your code gets scanned 10 times or 10,000 times, it works.
Your QR code is clean. No branded logo stamped in the middle, no interstitial, no 'powered by' overlay.
See how many times your code has been scanned — included free. No paid upgrade needed to know it's working.
Download a print-ready PNG at high resolution. Works for flyers, menus, business cards, and large-format print.
Why dynamic QR codes matter (and when static is enough)
A dynamic QR code is just a static QR code that encodes a redirect URL — usually something short — instead of the final destination. When someone scans the code, their phone hits the redirect, the redirect server looks up where you currently want it to go, and forwards the user there. Because the lookup happens server-side, you can change the destination at any time without modifying the printed code. This single architectural choice is the difference between a code you print once and use forever, versus one that becomes unusable the moment a URL changes.
Static codes still have their place — a code on a presentation slide, a one-time event link, a temporary URL that's guaranteed not to change. But for anything printed onto physical material that will exist for more than a few weeks, dynamic is almost always the right call. The cost of being wrong (a reprint run) is so much higher than the cost of being right (using a free dynamic generator) that there's rarely a reason to take the risk.
When dynamic is essential
Anything with a long physical shelf life — product packaging, museum signage, real estate signs, business cards, restaurant menus, event venue signage. Anything where the destination URL might plausibly change in the next year. Anything where the cost of reprinting is meaningful. Anything where you want to track scan analytics. In all of these cases, the editable destination is what makes the code reliable over time.
What "free" should actually mean
Many tools that call themselves free QR code generators have hidden catches: codes expire after a trial period, the platform watermarks the code with their logo, scans are limited per month, or you need to pay to access analytics. A genuinely free dynamic QR code generator has none of those gates. The code you create today should keep working a year from now without you upgrading anything. Scanta's free tier is built around this principle — no expiry, no scan caps, no watermark, no required upgrade.
Print readiness and best practices
For print quality, the QR code download should be high enough resolution to scale up without pixelation. Scanta exports PNG at a resolution that prints cleanly from a small label up to a large banner. The minimum recommended print size is one inch (2.5 cm) for close-range scanning; double that for codes meant to be scanned from a few metres away. Always test the code with several phones across iOS and Android before sending a print run — different camera apps handle low-contrast or low-resolution codes differently.
Frequently asked questions
What is a dynamic QR code?
A dynamic QR code encodes a short redirect URL instead of the final destination. You can change where the redirect points from a dashboard at any time — without touching the printed code. Static QR codes encode the destination directly and cannot be changed after printing.
Is Scanta's dynamic QR code generator really free?
Yes. Scanta's free plan includes dynamic (editable) QR codes with no expiry, no scan caps, and no watermarks. You can create a code, edit its destination anytime, and see basic scan counts — all without a credit card.
Do the QR codes expire?
No. Scanta's dynamic QR codes redirect indefinitely on the free plan. There is no trial period or expiry clock.
Is there a scan limit?
No. Scanta does not cap the number of scans on any plan, free or paid.
Can I edit the destination after printing?
Yes — that's the whole point. Log into your Scanta dashboard, find the code, and update the destination URL. The physical printed code keeps working and now points to the new address.
