Wi-Fi QR Code Generator

WiFi QR code generator: create a code in seconds

A Wi-Fi QR code stores your network name, password and security type in a standard format that phone cameras understand. When a guest scans it, the phone shows a "Join network" prompt — no typing of a 20-character password, no mistakes between l and 1. This Wi-Fi QR code generator builds that code for you and checks that it decodes correctly.

What is inside the code

The data follows the widely supported WIFI: syntax:

WIFI:T:WPA;S:MyHomeWiFi;P:correct-horse-battery;;

• T — security: WPA (also covers WPA2 and WPA3), WEP or nopass for an open network.
• S — the SSID (network name).
• P — the password, omitted for open networks.
• H:true — added only for hidden networks.

Backslashes, semicolons, commas, colons and double quotes in the name or password must be escaped with a backslash. The tool does this automatically, which avoids the most common reason home-made Wi-Fi codes fail.

Where to use it

• A framed card in a guest room, holiday rental or meeting room.
• The counter of a café, shop or waiting room, next to the guest network name.
• An onboarding document for new employees on the guest or IoT network.

Use a separate guest network where possible: anyone who can photograph the code can read the password from it.

Printing and display

Download the SVG version for printing: it scales to any size without blurring, so the same file works for a table tent, an A4 sign or a sticker. A width of 3–4 cm is comfortable to scan from arm's length. Add a short caption such as "Scan to join Wi-Fi" and, for guests whose phones cannot scan, also print the network name and password in text. If you prefer to show the code on a tablet or TV, the PNG download at 1024 px is sharp enough for most screens.

Troubleshooting

If the phone reports that it cannot join, compare the SSID character by character — names are case-sensitive and trailing spaces count. Some older Android phones need a QR scanning app instead of the camera. For other content, such as a link to your menu, use the general QR code generator; to check what an existing sticker contains, use the QR code reader.

Privacy

Your network name and password are turned into a QR code locally in your browser, and nothing is transmitted to our servers while you type or download. Save & Share is different: the link stores the form, including the network name and password, on our server, so do not use it for a network whose password must stay private.
