Wi-Fi QR Code Generator
Make a QR code that joins your Wi-Fi network when scanned, so guests do not have to type the password, and download it as an image or a card to print.
Wi-Fi QR Code Generator: The page writes your network details in the Wi-Fi format phone cameras recognise, WIFI:T:WPA;S:name;P:password;;, escaping any semicolons, commas, colons, quotes, or backslashes in the name or password so they cannot break it, and draws it as a QR code. The card adds the network name and password in print for anyone whose phone cannot scan. Runs 100% locally in your browser with zero server file uploads.

Runs entirely in your browser
Type the network name and password exactly as your router shows them: capitals, spaces, and symbols all count.
Printing a code that scans first time
Print the code at least 3 cm (1.2 in) wide and keep the white border around it: phones find a code by its quiet margin as much as by its squares. Dark on white scans best, and a glossy laminate can reflect ceiling lights into the camera, so a matt finish or a slight angle helps.
If you change the Wi-Fi password, the old code stops working, since it holds the password itself rather than a link. Make a new code whenever the password changes, and keep the network name the same so saved devices reconnect.
When a phone will not join
Check the name and password letter by letter, since both are case-sensitive and a trailing space counts. Then check the security type in your router's settings, and whether the network is hidden. The QR code reader shows exactly what a code contains, which is the quickest way to spot a typo in a code someone else made.
How to use it
- Type the network name and password exactly as your router shows them.
- Choose the security type; most networks use WPA.
- Scan the code with your phone to test it, then download it or print the card.
Privacy & limitations
The code is made in your browser. Your network name and password are never sent anywhere or stored.

Frequently asked questions
Which phones can join Wi-Fi from a QR code?
iPhones join from the Camera app, from iOS 11 on. Android phones from Android 10 on can scan from the Wi-Fi settings screen, where Add network has a QR code button, and many Android camera apps and Google Lens read the code too. The phone shows the network name and asks before joining.
Which security type should I choose?
WPA for almost every home or office router, including WPA2 and WPA3 networks. WEP only for very old routers, and No password for an open network. If the code does not connect, check the security type in your router's settings and scan again.
Is it safe to put my Wi-Fi password in a QR code?
The code contains the password in plain text, so anyone who scans it, or photographs it, can read it. Put it where you would write the password on a card: inside your home or at a counter, not in a public window. A separate guest network keeps visitors off the devices on your main one.
What if my password has special characters?
Type it exactly as it is. Semicolons, commas, colons, double quotes, and backslashes have a meaning in the Wi-Fi format, so the page escapes them with a backslash, which is how phones expect to read them.
