Wi-Fi QR Code Generator

Practically all current ones. iPhones (iOS 11+) and most Android phones (Android 10+) read Wi-Fi codes straight from the built-in camera app — point, tap the prompt, and it offers to join. Older phones may need a QR scanner app.

Pick WPA/WPA2/WPA3 for virtually every modern home or office router — it is the default. Choose WEP only for very old hardware, and “open” for a password-free network. It must match your router’s actual setting or the join will fail.

No. The network name and password are turned into the QR image inside your browser. Nothing is uploaded, logged or stored — you can even disconnect from the internet after the page loads and it still works.

The password is embedded in the code, so anyone who photographs it can extract it. That is fine for a home or café where you would share the password anyway, but do not post it publicly online, and use a guest network for extra separation.

They are handled automatically. Characters that the format treats specially — such as ; , : " and backslash — are escaped for you, so passwords with symbols encode correctly.

PNG for screens and quick sharing; SVG for printing, because it scales to any size without blurring. Both encode the identical network details.

A hidden network does not broadcast its name, so phones will not find it unless told to look. Only tick “hidden” if you deliberately disabled SSID broadcast on your router; for normal networks, leave it off.

That usually means the code and the join succeeded but something else is wrong: the wrong password was entered originally, the router is down, or a captive portal (a sign-in page) needs completing. Double-check the password field matches the router exactly.

Yes. The code is a snapshot of the details you entered. Change the Wi-Fi password and the old code stops working — make a fresh one and reprint it.

Yes, as long as you are allowed to share access. For public venues, a guest SSID with its own password is best practice so scanning does not expose the main network.
