About this tool
Type your network name and password and the Wi-Fi QR code appears instantly. Guests point their phone camera at it and join without typing anything. Download it as PNG or SVG, or print a ready-made sign with the network name and, if you like, the password spelled out.
When to use it
Guests at home
No more reading out a 20-character key. Stick the sign by the door or on the fridge and everyone connects in one tap.
Vacation rentals and guesthouses
A sign in the rental saves you the "what's the Wi-Fi password?" messages. The code keeps working until you change the password.
Cafés, waiting rooms, offices and meeting rooms
Print an A5 table card or an A4 wall sign. For a guest network you can leave the password off and let the code do the work.
How to use
- Enter the network name (SSID) and password.
- Pick the security type, usually WPA / WPA2 / WPA3.
- Scan the code with your own phone to check it.
- Download the image or print the sign in the paper size you need.
How it works
The QR code holds a standard string that Android and iOS both understand: WIFI:T:WPA;S:network name;P:password;;. Special characters in the name and password are escaped so the phone reads them exactly. You can see the encoded text under the preview.
Everything runs in your browser. The Wi-Fi password is never sent or saved and is gone when you close the page. The sign is laid out and handed to your browser's print dialog, which can also save it as a PDF.
Tips for best results
- Always scan the code with your own phone before printing it.
- If your router supports it, set up a separate guest network so visitors can't reach your devices.
- Network names are case-sensitive and include spaces: copy yours exactly.
- Change the Wi-Fi password and you'll need a new code and a new sign.
- Keep a dark code on a light background: pale colors scan poorly.
Common problems and fixes
The phone reads the code but won't connect
Check the exact network name, the password and the security type. A WPA3-only network won't accept older phones.
The camera doesn't offer anything
On some Android phones, open Google Lens or the "Scan QR code" option in Wi-Fi settings. Make sure the code is sharp and well lit.
The sign spills onto a second page
In the print dialog, choose the same paper size as in the tool, set scale to 100% and turn off headers and footers.
Frequently asked questions
Is my Wi-Fi password sent to ZanaKit?
No. The QR code is built in your browser and nothing is transmitted or stored.
Does a Wi-Fi QR code work on iPhone and Android?
Yes. The iPhone camera reads it since iOS 11, and most recent Android phones do too, directly or through Google Lens.
Does the code expire?
No. It contains the network name and password, with no link to an outside service, so it works for as long as those don't change.
Can I leave the password off the sign?
Yes, untick the option and only the QR code will let people join.
What about a hidden network?
Tick "Hidden network" so the phone knows to look for a network that doesn't broadcast its name.
