WiFi QR Code Generator
EverydayGenerate a QR code for your WiFi network. Guests scan it to connect instantly — no password typing needed. Free, browser-based, password never leaves your device.
What is a WiFi QR Code?
A WiFi QR Code Generator creates a scannable QR code that encodes your wireless network name (SSID) and password in a format that iOS and Android camera apps recognise automatically. Instead of reading out a WiFi password character by character, guests point their phone camera at the code and tap once to join — no typing required.
The WiFi QR code format (WIFI:T:{security};S:{ssid};P:{password};;) is supported natively by Apple's Camera app on iOS 11 and later (released 2017) and by Android 10 and later, as well as Google Lens on earlier Android versions. When a compatible device scans the code, it shows a system prompt: "Join [Network Name]?" — one tap connects without ever revealing the password to the guest.
This generator builds the correctly escaped WiFi format string from your inputs, renders it as a QR code using the same library as the QR Code Generator, and gives you a downloadable PNG. All processing happens in your browser — the password is never transmitted, stored, or logged anywhere.
Common physical uses: laminated cards on café and restaurant tables (replacing the hand-written password note), printed cards at Airbnb properties and short-term rentals, reception desk displays at coworking spaces, and printed inserts in new employee welcome kits. Digital uses: image shared in a building-wide Slack channel or WhatsApp group when IT changes the office WiFi password.
How to use this WiFi QR Code calculator
- Enter your Network Name (SSID) — type the WiFi network name exactly as it appears in your router's settings (case-sensitive).
- Choose the Security Type — select WPA/WPA2/WPA3 for all modern routers. Select WEP only for older hardware. Select "No password" for completely open networks.
- Enter your WiFi password — use the Show/Hide toggle to verify you have typed it correctly. Special characters (semicolons, backslashes, quotes) are escaped automatically.
- Check "Hidden network" only if your router does not broadcast its SSID — leave unchecked for standard routers.
- Scan the preview with your phone before distributing — confirm it connects to the correct network.
- Click Download PNG and use the image in your printed materials or share it digitally.
Formula & Methodology
The WiFi QR code uses theWIFI:scheme, an industry convention (not an official ISO standard but universally supported by modern mobile OS cameras): Format string:WIFI:T:{security};S:{ssid};P:{password};H:{hidden};;Variable definitions: -{security}—WPA,WEP, ornopass-{ssid}— the network name, with\,;,,,",:escaped with a backslash -{password}— the WiFi password, with the same characters escaped -{hidden}—trueif the SSID is hidden, omitted otherwise - The double;;terminates the string **Escaping rule:** Any occurrence of\,;,,,", or:in the SSID or password is prefixed with\. **Example:** - Network:HomeNet_5G, Password:myP@ss;word!, Security: WPA - Escaped password:myP@ss\;word!- Final string:WIFI:T:WPA;S:HomeNet_5G;P:myP@ss\;word!;;- The QR code encodes this string at error correction level M (15% recovery), 256×256 pixels
