QR code generator that never expires

The content is stored in the pattern itself: the code keeps working forever without relying on any website.

Your files never leave your device: everything is processed right here in your browser. Nothing is uploaded or stored.

How to use it

  1. Choose the type: link, text or Wi-Fi.
  2. Type the content — the QR code appears instantly.
  3. Download PNG (screens, documents) or SVG (print at any size).

When this helps

Why do some QR codes “expire”?

Many sites make dynamic QR codes: the code points to the provider’s own address, which then redirects to your link. When the free trial ends or the service shuts down, the printed code stops working. Here the QR code is static: your link is inside the pattern, so there is nothing that can expire.

FAQ

Does the QR code expire?

No. It stores the content directly and works as long as the destination exists.

Can I change the link after printing?

No — that’s the trade-off versus dynamic codes. If the link may change, point it to a page of your own that you can update.

Can I use it commercially?

Yes, free and without attribution.

Which format for a print shop?

SVG: it’s vector and stays sharp at any size. Keep good contrast (dark code on a light background).
