Error correction

Higher levels still scan when the code is dirty or scratched, but the code gets denser.

Round dots

Logo in the middle

Logo image address

Logo size

With a logo, error correction switches to High (30%) so the code still scans. The logo is at most 22% of the code width.

The QR code is made in your browser. Nothing is sent to our server.

Do QR codes expire?

No. A QR code only holds what you typed, so it scans forever. A code with a link only works while that page is online.

How do I know how many people scanned it?

Shorten the link first, then make the QR code for the short link: every scan counts as a click on the link’s Stats page. In the Dashboard, each link has a QR button.

Does a logo in the middle make it harder to scan?

The logo covers part of the code. The tool switches error correction to High (30%) and keeps the logo at most 22% of the code width, so it still scans. Test-scan before printing in bulk.
