WiFi QR Code Generator Online — Free
Runs 100% in your browser — your files never leave your device.
Reading passwords aloud or writing them on sticky notes is how guest WiFi has always worked — until QR codes fixed it. Enter your network name and password, and get a code guests can scan with their phone camera to join instantly. The code is generated locally; your credentials never leave your device.
How it works
- 1
Enter your network details
Type the network name (SSID), password, and security type — WPA, WEP, or open.
- 2
Preview the code live
The QR code updates as you type; mark the box if the network is hidden.
- 3
Download and print
Save the PNG and put it where guests can scan it — a fridge, a desk, a wall.
About this tool
What the Wi-Fi QR encodes
The tool builds the standard Wi-Fi configuration QR: network name, password, encryption type, and hidden-network flag encoded so any modern phone camera can join the network on scan — no more spelling passwords out to guests.
The guest-network workflow
Generate the QR for your guest network, print it, and frame it where guests sit. Guests scan and connect without you revealing or repeating the password verbally — and since the password lives in the QR, rotating it means reprinting, which is one more argument for a dedicated guest network.
Security notes
Anyone who scans the QR holds your Wi-Fi password — treat the printed code like the password itself. For shared spaces, prefer a guest network isolated from your main devices, and rotate the password periodically by regenerating the code.
Frequently asked questions
Which phones can scan it?
iOS and Android camera apps recognize the standard Wi-Fi QR format natively — no app needed on anything from the last several years.
Does the QR reveal my Wi-Fi password?
Yes — that is the mechanism: the code contains the credentials. Anyone who scans joins the network, so print it only where your guests can see it.
What encryption type should I pick?
WPA/WPA2 or WPA3 — whatever your router actually uses. Open networks need no password field; WEP is obsolete and insecure.
