What Is a Static QR Code?
A static QR code encodes a URL or piece of data directly into the pattern of the code itself. The information is baked in permanently — once generated, it cannot be changed. If you generate a QR code for "https://flexotools.com," that pattern will always point to that exact URL, forever.
Static QR codes are completely free to generate and have no expiry date. They do not require any account, subscription, or ongoing service to keep working. As long as the destination URL exists, the QR code works.
- ✓Completely free
- ✓No account or subscription needed
- ✓Never expires
- ✓No third-party dependency
- ✓Works offline if content is self-contained
- ✗Cannot change destination after printing
- ✗No scan tracking or analytics
- ✗URL visible inside the code pattern
- ✗Long URLs create dense, harder-to-scan codes
What Is a Dynamic QR Code?
A dynamic QR code does not encode your destination URL directly. Instead, it encodes a short redirect URL managed by a third-party service. When someone scans the code, they are first sent to the redirect service, which then forwards them to your actual destination.
Because the actual destination is stored on the redirect service — not in the code itself — you can log into the service and change where the code points at any time, without reprinting the physical code. The service also logs scan counts, locations, and device types.
The trade-off: dynamic QR codes require a paid subscription to keep working. If you cancel your plan or the service shuts down, every dynamic QR code you printed stops working instantly — even codes that are physically unchanged.
- ✓Change destination without reprinting
- ✓Scan analytics (count, location, device)
- ✓Shorter redirect URL = cleaner code pattern
- ✓Can pause or redirect expired campaigns
- ✗Requires paid subscription
- ✗Codes break if you cancel or service closes
- ✗Dependent on third-party uptime
- ✗Overkill for most personal use cases

Which Should You Use?
→ Static. Your Instagram or LinkedIn URL is not going to change. Free, permanent, no risk.
→ Static. The URL should be permanent anyway. Don't pay monthly for something that never needs to change.
→ Dynamic makes sense here. You print the code once on menus and update the linked PDF each season without reprinting.
→ Dynamic. Being able to redirect the code to a new offer after printing is the main use case dynamic codes were designed for.
→ Dynamic, if analytics matter enough to pay for. Alternatively, use a URL shortener with built-in tracking (like Bitly free tier) and make a static QR code from that shortened URL.
The Free Alternative to Dynamic QR Codes
If you want scan tracking without a subscription, there is a free workaround: create a short link using a free URL shortener (Bitly, T2M free tier, or your own domain redirect), then generate a static QR code from that short link.
The shortener dashboard shows you click counts and basic analytics for free. The QR code itself is static and permanent. You do not get the ability to change the destination after printing — but for most use cases, that is the only dynamic feature you do not need anyway.
💡 Bonus benefit: Short URLs also produce simpler, less dense QR code patterns — which scan faster and more reliably than QR codes encoding long URLs directly.
