WiFi QR Code Generator
This free QR code generator for WiFi turns your network name and password into a scannable QR code. Guests point their phone camera at the code and join your network in seconds — no typing a long password, no spelling out the network name, and no more sharing the password out loud. Type in your details, hit Generate, and download the code as a PNG to print or share.
The exact name of your WiFi network, as it appears in the list of available networks.
Leave this blank if your network has no password. Passwords are case-sensitive.
How it works
A WiFi QR code is a small block of text, written in a standard format, that is encoded as a QR code. When a phone camera reads it, the phone recognizes the text as WiFi login details and offers to join the network. The format looks like this:
Each part has a job. T is the security type: WPA for WPA and WPA2 networks, WEP for older WEP networks, or nopass for an open network with no password. S is the SSID, the name of the network. P is the password, and it is left out entirely when the network is open. H is true only when the network is hidden, meaning the router does not broadcast its name. The double semicolon at the end marks the end of the code. This generator builds that text for you, so you never have to remember the exact punctuation.
To use it, type your network name exactly as it appears on your router, including capital letters and spaces — WiFi names are case-sensitive, and a single wrong letter means the phone will try to join a network that does not exist. Choose the security type that matches your router. Most home routers bought in the last ten years use WPA2, so WPA is the right choice for almost everyone. If your network is open, pick None and leave the password blank. Tick the hidden-network box only if you turned off SSID broadcast in your router settings; for a normal network, leave it off.
Press Generate and the QR code appears on the page. Test it before you print it: point your own phone camera at the code and check that it offers to join the right network. If it does, use the Download PNG button to save a clean image you can print on a card, stick on the fridge, or add to a guest welcome sheet. The PNG is drawn from the same QR data shown on screen, so what you download is exactly what you tested.
Your password never leaves your device. The QR code is generated entirely in your browser, and nothing you type is sent to a server or stored anywhere. That matters because a WiFi password is the key to your home network — a generator that uploads it would be a security risk. Here, you can even disconnect from the internet after the page loads and the generator will still work.
One practical tip: print the code at least two inches wide so older phones can scan it from a comfortable distance, and use a dark code on a light background with a plain border of white space around it. A code printed too small, or on a glossy surface that reflects light, is the most common reason a scan fails. If guests still have trouble, check that the network name and password are typed exactly right — a trailing space in the SSID field is an easy mistake to make.
Worked example
A family sets up a guest code for their home network, called HomeWiFi, protected with WPA2 and the password secret123.
Step 1: Type HomeWiFi in the network name field.
Step 2: Choose WPA / WPA2 as the security type.
Step 3: Type secret123 in the password field and leave the hidden-network box unticked.
Step 4: Press Generate QR Code.
The generator builds the payload WIFI:T:WPA;S:HomeWiFi;P:secret123;; and draws the matching QR code. A guest points their phone camera at it, taps the join prompt, and is connected to HomeWiFi without typing anything. The family downloads the PNG and tapes a printed copy inside the guest room, so every visitor can connect on their own.
FAQ
How do I scan a WiFi QR code?
Open your phone camera and point it at the code. On iPhone and most Android phones, a notification appears offering to join the network — tap it and you are connected. If nothing appears, open the camera settings and make sure QR code scanning is turned on, or use the QR scanner in your WiFi settings.
Is it safe to share a WiFi QR code?
Sharing the code is the same as sharing the password: anyone who scans it can join your network. Only share it with people you trust, and use a guest network if your router supports one, so visitors cannot reach your personal devices. Never post a photo of the code publicly.
What if my network has no password?
Choose None as the security type and leave the password field blank. The generator then builds a code without a password part, and phones will join the open network directly when they scan it.
Why does my phone say the network was not found?
The most common cause is a typo in the network name — WiFi names are case-sensitive, so HomeWiFi and homewifi are different networks. Check the exact spelling, including spaces, and make sure the hidden-network box matches your router settings. If the network is hidden and the box is unticked, the phone will not find it.
