QR code generator

Good to know

Does the QR code expire?

No. The code holds your text itself, so it works for as long as that text (for example the link) does. It is not a redirect through a third party service.

Which error correction level should I pick?

Medium is a good default. Higher levels let a code survive scratches or a logo on top, but they add modules, so the code gets denser and harder to scan at small sizes.

What is the quiet zone?

The empty border around the code. Scanners use it to find the edges, and the QR standard asks for 4 modules. Cropping it too tightly is the most common reason a code fails to scan.

PNG or SVG?

SVG stays sharp at any size, so use it for print and posters. PNG is fine for screens and documents.
