Frequently asked questions
Do these QR codes expire?
No. The content is encoded directly into the code rather than routed through a redirect service, so it works for as long as the destination is valid.
Will a center logo stop the code from scanning?
No, as long as error correction is medium or higher. The logo hides some modules, and the QR error-correction data fills in the gap - use Q or H if your logo is large.
Should I download PNG or SVG?
PNG is ready for the web and most documents. SVG is a vector, so it stays perfectly sharp at any print size - use it for posters, packaging, or professional print work.
Can I encode Wi-Fi details?
Yes, most QR scanners recognise the Wi-Fi format and offer to connect directly when scanned.
