How to create a WiFi QR code
- Type your network name (SSID) exactly as it appears in your WiFi list.
- Enter your password. Leave it empty if the network is open.
- Choose the encryption type — most modern routers use WPA/WPA2/WPA3.
- Download the QR code as a PNG or SVG and print it, share it, or stick it on the fridge.
How guests use it
No app needed. On iPhone (iOS 11+) and most Android phones (9+), open the built-in Camera app and point it at the QR code. A notification appears — tap it and the phone joins the network automatically.
Where WiFi QR codes shine
- Airbnb & short-term rentals — print and frame a card at the door. Guests join without messaging you.
- Cafés & restaurants — put it on the menu or a table tent. No more "what's the WiFi password?" interruptions.
- Home guest networks — share access without exposing your main network password.
- Offices & co-working — quick onboarding for visitors.
- Events & conferences — scan once, connected all day.
Is it safe?
The QR encodes your password in plain text — anyone who scans it can read it. That's normal and how the standard works, but it does mean you should only share the code with people you'd normally share the password with. For sensitive networks, create a separate guest network on your router and make a QR for that.
This tool never uploads anything. The QR is generated locally in your browser using the open-source qr-code-styling library. Your SSID and password stay on your device.
Technical details
WiFi QR codes use a standard format defined by Wi-Fi Alliance / Java MeCard spec:
WIFI:T:WPA;S:<network>;P:<password>;H:<true|false>;;
Special characters in the SSID or password (\, ;, ,, :, ") are escaped with a backslash. The T field is one of WPA, WEP, or nopass. H:true indicates a hidden SSID.
FAQ
Does this work on older phones?
iOS 11+ (2017) and Android 9+ (2018) support WiFi QR codes natively. Older devices can still scan the code using any QR reader app.
Can I change the colors or add a logo?
Yes — head over to the main generator. It has full styling, logo upload, color controls, and exports to PNG, SVG, and JPG.
Why does my phone say "Unable to join"?
Double-check the SSID and password match exactly (including capitalization). If the network is hidden, make sure the Hidden checkbox is ticked.
Can I print the QR on a poster or sticker?
Absolutely — download the SVG for infinite-resolution printing, or the PNG at the size shown. Keep a quiet zone (white border) around the code so scanners can find it.
Does this code expire?
No. It's a static QR — as long as your WiFi password doesn't change, the code works forever.
