# Wi-Fi QR code generator

https://tools.santara.ai/wifi-qr-code-generator/

Type your network name and password and the QR code builds as you type. Guests point their phone camera at it and join without typing anything. Download it free as a PNG or SVG for a sign, a guidebook or the fridge door. Everything happens in your browser.

## How it works

Phones understand a short text format for Wi-Fi: the security type, the network name, the password and whether the network is hidden. The tool writes that text and turns it into a QR code with medium error correction, so it still scans when the print is a little scratched or creased.

Characters that the format uses as separators — backslash, semicolon, comma, colon and double quote — are escaped, so names like “Floor 3; Room A” still work. Vietnamese, Thai and other non-Latin names are encoded as UTF-8, which iPhone and Android cameras read.

The code is drawn on this page with JavaScript. Nothing you type is put in the address bar, saved, measured or sent to a server, so the password stays on your device.

- `WIFI:T:<WPA|WEP|nopass>;S:<network name>;P:<password>;H:<true|false>;;`

## Questions hosts ask

### Which phones can scan a Wi-Fi QR code?

iPhones on iOS 11 or later and most Android phones from the last few years join straight from the camera app. Older Android phones may need Google Lens or the QR scanner in quick settings.

### What happens if I change my Wi-Fi password?

The old code stops working, because the password is inside it. Make a new code and replace every printed copy the same day.

### Should I use my main network for guests?

A separate guest network on your router is safer: guests get internet without reaching your cameras, smart locks or computers. Most routers sold in the last few years offer one.

### Is my password stored anywhere?

No. This page has no analytics and makes no network requests with what you type. Close the tab and the password is gone.
