How does a WiFi QR code work?

A Wi-Fi QR code encodes the network name, security type, password, and optional hidden-network flag in a standard Wi-Fi QR string. Compatible phones can offer to join the network after scanning it.

Is my WiFi password uploaded anywhere?

No server-side lookup is required. The Wi-Fi string and QR code are created in the browser.

Does this work with WPA2 or WPA3?

For common personal Wi-Fi networks, the standard WPA QR format is used. Device behavior can vary, especially on WPA3-only networks, so test the code on the devices you expect guests to use.

Can I print a guest WiFi card?

Yes. The tool includes a print-friendly guest network card with an option to show or hide the password text.

WiFi QR Code Generator

Turn a Wi‑Fi network name and password into a scannable QR code so guests can connect without manually typing credentials. Download the QR code, copy the encoded Wi‑Fi string, or print a guest network card.

Wi‑Fi Network

Network Name (SSID)

Enter the network name exactly as it appears in Wi‑Fi settings. SSIDs are case-sensitive.

Security Type

Wi‑Fi Password

Hidden network Includes the hidden-network flag in the Wi‑Fi QR payload.

The network details are used locally to create the QR code. This tool does not need a server-side API to encode your SSID or password.

Security

WPA / WPA2 / WPA3 Personal

Open your phone camera, scan the QR code, and follow the prompt to join the network.

Show password text on guest card The QR code always contains the credentials. This option only controls whether the password is printed as readable text.

Wi‑Fi QR String

Special characters in the SSID and password are escaped automatically for the Wi‑Fi QR format.

How the WiFi QR Code Generator Works

Enter the wireless network name (SSID), choose the security type, and provide the password when the network requires one. The tool converts those values into the standard Wi‑Fi QR string format and renders the QR code directly in your browser. Compatible phones can scan the code and offer to join the network without manually typing the password.

The generator also creates a printable guest Wi‑Fi card. You can choose whether the password appears as readable text on the card; the QR itself still contains the credentials needed for the connection.

Wi‑Fi Security Options

WPA / WPA2 / WPA3 Personal

Use the WPA option for typical password-protected home and guest networks. The commonly supported Wi‑Fi QR format uses the WPA security token for WPA-family personal networks. Support for WPA3-only configurations can vary by device, so test your generated code with the phones you expect visitors to use.

WEP

WEP is included for compatibility with older networks, although WEP is obsolete and insecure compared with modern Wi‑Fi security. If you control the network, migrating to modern WPA2 or WPA3 security is preferable.

Open Networks

Select Open / No Password when the network does not require a Wi‑Fi password. The QR code will omit password credentials.

Hidden Networks

Enable Hidden network when the SSID is configured not to broadcast. The generated Wi‑Fi string includes the hidden-network flag. Device support for automatically joining hidden networks may vary.

Tips for Reliable Wi‑Fi QR Codes

Enter the SSID exactly, including capitalization, spaces, and punctuation.
Use strong foreground/background contrast for easier scanning.
Keep enough blank margin around the QR code.
Scan the finished code before printing or sharing it.
If guests cannot connect automatically, verify the network name, password, security mode, and whether the network is hidden.
For guest access, consider using a separate guest network rather than sharing credentials for your primary private network.

WiFi QR Code Generator FAQ

Does this send my Wi‑Fi password to a server?

No server-side lookup is required. The Wi‑Fi payload and QR code are created in the browser. The QR rendering library itself is loaded as a browser script from a CDN.

Does it work on iPhone and Android?

Modern iPhone and Android devices commonly recognize Wi‑Fi QR codes through their camera or QR scanning interface. Exact behavior can vary by operating-system version and network configuration.

Can I create a QR code for WPA2 or WPA3?

Yes. For common personal Wi‑Fi networks the tool uses the broadly supported WPA Wi‑Fi QR token. WPA3-only behavior can vary across devices, so test the result before relying on it for guests.

Can I create a QR code for a hidden Wi‑Fi network?

Yes. Select Hidden network and the QR string will include the hidden-network flag.

Can I hide the password on the printed card?

Yes. Leave Show password text on guest card turned off. The printed card will mask the password while the QR code continues to contain the credentials needed to connect.

Why does my Wi‑Fi QR code not connect?

Check the SSID spelling and capitalization, password, selected security type, and hidden-network setting. Some phones or unusual enterprise/WPA3 configurations may not support automatic joining from the common Wi‑Fi QR format.
