WiFi QR Code Generator
Turn your network name and password into a QR code that connects a phone instantly — no typing, no spelling out a password out loud. Made entirely on your device; your password never leaves your browser.
One scan, instant connection
A WiFi QR code encodes your network name, password and security type into a single scannable image using a standard format that both iPhone and Android cameras recognize natively. Instead of a guest squinting at a sticky note and typing a long password on a phone keyboard, they open the camera, point it at the code, and tap one prompt to join.
Everything happens right here in your browser: the QR code is drawn on a canvas on your device and the password is never uploaded or stored on our servers. That makes it safe to generate a code for your real network and print it for a cafe counter, office reception, guest room or Airbnb welcome card. Prefer a code for a link instead of WiFi credentials? Use the plain QR code generator, or a trackable QR code if you also want to see scan counts.
Using a WiFi QR code safely and reliably
What is inside the code
A WiFi QR code is plain text in a standard layout, for example WIFI:T:WPA;S:MyNetwork;P:mypassword;;. It holds the security type (T), the network name (S) and the password (P), plus an optional flag for hidden networks. Anyone who scans the code can read those values, so treat the printed code exactly like a written-down password.
Use a guest network where you can
If your router supports a separate guest network, make the code for that one. Guests then get internet access without being able to reach your computers, printers or smart-home devices, and you can change the guest password without disrupting your own devices.
Match the security type exactly
Choose the same security setting your router uses. WPA and WPA2 networks use the WPA option, older routers may use WEP, and an open network uses none. A mismatch is the usual reason a scan shows the network name but fails to connect. Network names and passwords are case-sensitive, and special characters such as semicolons, commas and quotation marks are escaped for you.
Where to put it
Frame the printed code at reception, in a guest room, on a cafe counter or on a rental welcome card, at a height where a phone can be held steady about 20–30 cm away. Print it at least 3 cm wide with a clear white margin, and keep it away from glossy surfaces that reflect light into the camera.
When you change the password
A WiFi QR code is fixed: it stores the password itself, so after you change the password the old printed code stops working and must be replaced. Rotating the password every few months, and after any event where many people had access, is good practice; keep a spare copy of the new code ready to print.
WiFi QR code questions
Does a WiFi QR code work on iPhone and Android?
Yes. Both open the network automatically with the built-in camera app — no separate scanner needed. On iPhone, point Camera at the code and tap the WiFi banner that appears. On Android, the camera or a quick QR shortcut in the notification shade does the same.
Is my WiFi password sent to your servers?
No. This tool builds the QR code entirely in your browser using JavaScript — your network name and password are encoded straight into the image on your own device and never sent anywhere. We log only that a WiFi QR code was generated, with your network name — your password is deliberately excluded from that log.
What if my network is hidden (not broadcasting its name)?
Check the "Hidden network" box before generating. That flags the QR code so connecting devices know to actively search for your SSID instead of waiting to see it listed.
Which security type should I pick?
Choose WPA/WPA2/WPA3 for almost any modern router — they all share the same QR encoding. Pick WEP only for very old hardware, or "No password" for an open guest network.
Does the QR code expire or stop working?
No. It keeps working for as long as the network name and password stay the same. If you change your WiFi password, generate a new code — the old one will no longer connect.
Can I print this and put it on the wall?
Yes — that's exactly what it's for. Download the PNG and print it on a card for your cafe counter, office reception, guest room or Airbnb welcome book so visitors connect in one scan.
