How to make a WiFi QR code
A WiFi QR code stores your network name, password and security type, so anyone who scans it joins instantly — no reading out a long password or typing it wrong. It is perfect for a café, holiday rental, office reception or a card on the fridge at home.
Encode your details in the format WIFI:T:WPA;S:NetworkName;P:Password;; then style the code with your colours and a logo and download a print-ready PNG or SVG. It is a static code, so it works forever with no account.
Tips for a great QR code
- The exact network name (SSID), matching case
- The security type — WPA/WPA2 for most networks
- The password exactly as set (leave blank for open networks)
- High error correction if you add a centre logo
- A short label like “Scan to connect to WiFi”
Tip: Print it at a large size and test it before you frame or laminate it.
Frequently asked questions
How does a WiFi QR code work?
The code encodes your network name, security type and password in a standard WiFi string. When a phone scans it, the camera offers to join that network automatically — no manual typing. The details live inside the code, so it needs no internet to work.
Is it safe to share my WiFi with a QR code?
It is as safe as reading the password aloud — anyone who can see the code can join. For a guest or café network that is fine; for a private network only display it where you trust who can scan it, or use a separate guest network.
Does the WiFi QR code expire?
No — it is a static code, so it works as long as your network name and password stay the same. If you change the password, just generate a new code.
Is this QR code generator free?
Yes — CalculatorAI's QR code generator is completely free. Create, customise and download as many static QR codes as you want as PNG or SVG, with no signup, no watermark and no scan limit. Static codes never expire. A free account adds dynamic (editable) codes with scan analytics.
Do the QR codes expire?
Static QR codes never expire — the data is encoded in the code itself, so they keep working forever with no account and no fees. Dynamic codes, which you can edit after printing and track, stay live as long as your free account is active.
Need an editable code with scan tracking?
Static QR codes are free forever and never expire. Want to change the destination after printing and see how many people scan — from where and on what device? Create a dynamic QR code and track every scan in the QR Codes dashboard.
