Search "free QR code generator" and you'll find dozens of tools. But a lot of people get a nasty surprise weeks later: the code they printed has stopped working, because the "free" code was actually a trial that expired. Let's clear up how this really works so you never get caught out.
Why some "free" QR codes expire
The catch is almost always that the tool made you a dynamic code on a free trial. A dynamic code routes through the provider's server, so if your trial ends and you don't pay, the provider can switch it off — and your printed code goes dead.
That's not how QR codes have to work. It comes down to the difference between two types.
Static codes are genuinely permanent
A static QR code has the link baked directly into the pattern. Nothing routes through a server, so there's nothing anyone can switch off. A static code works forever — even if the company that made it disappears. The trade-off: you can't edit it or track scans.
So if you want a free code that truly never expires, you want a static one — and you want a tool that offers static codes for free, with no trial trap.
When you genuinely need dynamic
If you need to edit the destination later (a menu, a promo) or track scans, you need a dynamic code, and that's a paid feature on most serious tools — fairly, because it costs them to keep the redirect running. The honest move is to choose a provider that, if you ever stop paying, shows a polite "paused" page rather than a broken link, and keeps your static codes free forever.
Rule of thumb: link that never changes → free static code. Link you'll edit or measure → dynamic code, and pick a provider that won't silently break your print.
How to make a permanent free one
- Go to a generator that offers free static codes — at QRYZEN, static codes are free and unlimited.
- Choose "Link QR" and pick Static.
- Paste your link (no need to type
https://), style it with your colours and logo, and download.
That code will work as long as the destination does — on a sticker, a poster or a billboard, with no expiry and no catch.
