How do I create a WiFi QR code for my guests?

Select the WiFi option, enter your network name (SSID) and password, choose the security type (WPA/WPA2), and generate the code. Guests can then scan it with their phones to connect automatically without typing the password.

What file formats can I download my QR code in?

Our generator supports multiple formats including PNG, JPG, SVG, and PDF. SVG format is recommended for printing as it maintains quality at any size without pixelation.

Do QR codes expire or have an expiration date?

Static QR codes never expire as they contain the data encoded within them. However, if the destination URL or information changes, you'll need to generate a new QR code. Dynamic QR codes can be updated without regenerating the code itself.
