About the Wi-Fi QR Code Generator
Tired of spelling out a 16-character password for every guest? Print a Wi-Fi QR code instead. Visitors open their phone’s camera, tap the notification and they’re online. It works great for cafés, restaurants, Airbnbs, offices, waiting rooms and your own living room.
The code generated here is a static QR code with your network details stored in the image itself, so it is free and never expires. It is drawn right in your browser: your network name and password are never uploaded or stored anywhere.
How to use
- Type your network name into Network name (SSID) exactly as it appears, including capitals and spaces.
- Enter the Password and pick the Security type. Most routers today use WPA/WPA2/WPA3; choose No password only for open networks.
- If your router hides its SSID, tick Hidden network.
- Scan the code with your own phone to confirm it actually connects.
- Click Download PNG or Download SVG and print it on a table tent, welcome card or wall sign.
Which phones can scan a Wi-Fi QR code?
- iPhone and iPad: the built-in Camera app (iOS 11 and later) shows a “Join network” prompt.
- Android: on Android 10 and later, use the camera app, Google Lens or the QR icon in Settings › Wi-Fi. Samsung Galaxy phones also scan from the Camera app.
- Laptops: they can’t easily scan a QR code, so print the network name and password as text next to it too.
The code contains a standard string such as WIFI:T:WPA;S:MyWiFi;P:password;;. Enterprise networks (WPA2-Enterprise with a username and password) can’t be shared this way.
Security: the QR code is your password
A Wi-Fi QR code stores the password in plain text. Anyone with a photo of it can join, and any QR reader app will display the password.
- For businesses and rentals, enable your router’s guest network and make the QR code for that. It keeps visitors away from your POS system, cameras and private devices.
- If you change the password, the old code stops working, so make and print a new one.
- Check that the code isn’t visible in photos you post on social media.
Printing tips
- For a table tent scanned up close, print at least 3 cm (about 1.2 in). For a wall sign scanned from 1–2 m away, go for 10 cm (4 in) or more. Rule of thumb: size = scanning distance ÷ 10.
- Add a short call to action like “Scan to join our Wi-Fi”. People are far more likely to try it.
- Matte paper works better than glossy lamination, which can reflect lights and confuse cameras.
FAQ
Does a Wi-Fi QR code expire?
No. The network details are stored in the image, so it works as long as your network name and password stay the same.
I scanned it but my phone won’t connect. Why?
Double-check the network name (it’s case-sensitive), the password and the security type. Unless your router is very old, WPA/WPA2/WPA3 is the right choice. For a hidden network, the Hidden network box must be ticked.
Is my Wi-Fi password saved on your server?
No. The QR code is generated locally in your browser and nothing you type is sent anywhere.
Do I need separate codes for 2.4 GHz and 5 GHz?
Only if the two bands have different network names. If they share one name, a single code is enough and the phone picks the band itself.
Does it work with WPA3?
Yes, choose WPA/WPA2/WPA3. Note that a router set to WPA3-only can’t be joined by older devices that don’t support WPA3, with or without a QR code.
