FAQ

How do I generate a WiFi QR code?

Select WiFi mode, enter the network name (SSID), password, and encryption type. The tool generates a standard WiFi connection QR code automatically.

What is the difference between PNG and SVG?

PNG is a raster format ideal for screens and sharing. SVG is vector-based, scales infinitely without quality loss, and is perfect for printing.

Do QR codes expire?

The QR code itself does not expire, but if it encodes a URL, the link will become inaccessible if the target page is removed.
