What is the best qr code generator without expiration?

Any tool that gives you a true static QR code will never expire. The tool matters far less than the code type.

The confusion in this thread comes from most generators defaulting to dynamic codes without saying so. A dynamic code stores a link to the provider's server inside the pattern, so when the trial ends, or the plan lapses, the redirect dies and every printed copy goes dead. A static code stores the actual data in the pattern itself. There is no server involved, so there is nothing that can be switched off.

How to verify a code is static before printing:

This takes ten seconds and removes the need to trust any marketing claim.

1. Generate and download the code.
2. Scan your own downloaded file with any reader app.
3. Read the decoded text.

If it shows the real URL or contact details, it is static and permanent. If it shows the provider's domain with a short code after it, such as qrco.de/abc123, it is dynamic and will stop working eventually.

Every tool in this thread can be checked this way in under a minute.

Tools that give genuinely unlimited free static codes:

• GoQR and QRCode Monkey are the lowest friction. No account, no watermark, unlimited. QRCode Monkey adds logo and colour options; GoQR is bare bones but fast.
• Adobe Express is the best-looking output if design matters, as mentioned above.
• IMQRScan offers unlimited free static codes with no expiry and no watermark, and generates them in the browser rather than on a server, so contact details are never uploaded anywhere. It does require a free account, but the good thing is you can upgrade to a paid plan 2.99$/month, if you need dynamic QR codes with editing and tracking.
• Microsoft Edge's built-in address bar QR button works and costs nothing, but the PNG it exports is too small for print.
