Free Wi-Fi QR code generator
Printing a Wi-Fi password on a card only helps if guests can read your handwriting and type it correctly. A Wi-Fi QR code skips that entirely — point a camera at it and the phone offers to join the network directly, no typing, no support calls. Popular for cafes, offices, Airbnbs, waiting rooms and home guest networks.
How the Wi-Fi QR format works
The code encodes your network name (SSID), password, and security type (WPA/WPA2/WPA3 or WEP) in a standard format that iOS and Android both recognize natively through the camera app — no third-party scanner needed. You can also mark a network as hidden if it doesn't broadcast its SSID.
Frequently asked questions
How does a Wi-Fi QR code work?
It encodes your network name, password and security type in a standard format. Scanning it prompts "Join Network" on the phone — no typing required.
Is my Wi-Fi password safe in the QR code?
The code is generated entirely in your browser — nothing is sent to a server. But anyone who scans a printed copy can join your network, so treat it like the password itself.
Does this work for WPA3 networks?
Yes. Choose WPA as the security type — the format covers WPA/WPA2/WPA3 the same way.
Can I brand it for guests?
Yes — add a logo, custom colors, and a "Scan for Wi-Fi" caption frame, useful for a printed guest Wi-Fi card.
