# Make a Wi-Fi QR Code

Stop spelling out a long Wi-Fi password. Enter the network name and password once, print the code, and guests join by pointing their phone camera at it.

**Quick answer:** To make a Wi-Fi QR code, enter the network name (SSID) and password, keep WPA security, and download the code as PNG or SVG. The iPhone and Android camera apps offer to join the network when they scan it. The code is made in your browser and the password is not sent anywhere or saved.

## How to use it

1. Type the network name (SSID) exactly as it appears, including capitals.
2. Type the password and keep WPA / WPA2 / WPA3 security unless your network is open or uses old WEP.
3. Tick Hidden network if your router does not broadcast the name.
4. Download PNG or SVG, test it with your phone, then print it.

## How the code works

A Wi-Fi QR code contains a short text in a standard format, for example `WIFI:T:WPA;S:HomeNetwork;P:secret;;`: the security type, the network name and the password. The camera apps on iPhone and Android recognise it and offer to join, so nothing has to be typed. Special characters such as ; and : in the name or password are escaped automatically.

## Printing and placing it

- **Size**: printed at 3 to 4 cm or more it scans easily from arm's length. Use SVG for the sharpest print at any size.
- **Keep the white border** (quiet zone) of 4 modules; scanners need it.
- **Test before printing** with two different phones.
- **Label it** with the network name, so people know what it is.

## Security

Anyone who scans the code can read the password, just as if it were written on the card. For visitors, use a guest network on your router and put that one in the code. The page builds the code in your browser; the password is not uploaded, not stored and not kept in the address bar.

## Frequently asked questions

### How do I scan a Wi-Fi QR code?

Open the camera app on an iPhone or Android phone and point it at the code; tap the notification to join. Some older Android phones need Google Lens or the QR scanner in quick settings.

### Does it work with WPA3?

Choose WPA / WPA2 / WPA3. Most phones join WPA2 and WPA3 networks from a WPA code; if a WPA3-only network is refused, test with the phones your guests use.

### Does the code stop working if I change the password?

Yes. The password is inside the code, so make and print a new one after changing it.

### Is my Wi-Fi password sent anywhere?

No. The code is created in your browser, and the password is not stored or sent.

### Does the QR code expire?

No. It is a static code that works as long as the network name and password stay the same.
