Connecting your Windows PC to a new Wi-Fi network usually means finding the network and manually typing its password. If the password is long or filled with numbers, symbols, and mixed-case letters, that’s both inconvenient and easy to get wrong.
A Wi-Fi QR code makes the process much easier. On supported Windows devices, you can scan a QR code containing the network’s Wi-Fi information and connect without manually typing the password.
Windows 11 can do this directly through the built-in Camera app. Open Camera, switch to Barcode mode, point your laptop’s webcam at the Wi-Fi QR code, select the detected link, and Windows will open Settings to let you add and connect to the network.
There are other options as well. For example, you can use a Wi-Fi QR scanner app from the Microsoft Store, which can be particularly useful for Windows 10 or when you need to scan a QR code saved as an image.
In this guide, we’ll explain how to connect to Wi-Fi with a QR code on Windows 11/10 using all of these methods.
What Is a Wi-Fi QR Code?
A Wi-Fi QR code is a QR code containing the information required to identify and connect to a wireless network.
It typically stores information such as:
- Wi-Fi network name (SSID)
- Password
- Security/encryption type
- Whether the network is hidden
A standard Wi-Fi QR code may contain information in a format similar to:
WIFI:T:WPA;S:HomeWiFi;P:ExamplePassword;;
Here, S represents the network name or SSID, P represents the password, and T identifies the security type.
You don’t normally need to read or understand this information yourself. A compatible QR scanner recognizes it and uses the details to help you connect.
Wi-Fi QR codes are commonly displayed on another smartphone, a router card or sticker, another computer, or printed signs in places such as hotels, offices and cafes.
Method 1: Connect to Wi-Fi Using the Windows Camera App
For Windows 11 users, this should be the first method you try.
Microsoft’s Camera app supports scanning QR codes and barcodes. When it detects a compatible Wi-Fi QR code, Windows can take you to Settings to add and connect to the network.
You don’t need to install a separate QR scanner.
Step 1: Open the Camera App
Press the Windows key and search for:
Camera
Click the Camera app in the search results.
If Windows asks for permission to use your webcam, allow access.
Your laptop needs a working built-in camera or your desktop PC needs a connected webcam for this method.
Step 2: Switch to Barcode Mode
Look at the modes available on the right side of the Camera app.
Select the Barcode/QR code icon to switch from the normal Photo mode to Barcode mode.
This tells Camera that you want it to detect a QR code rather than take a picture.
Step 3: Scan the Wi-Fi QR Code
Place the Wi-Fi QR code in front of your laptop’s webcam.
For example, if someone has shared their Wi-Fi QR code on their smartphone, hold the phone in front of your laptop’s camera.
Make sure:
- The complete QR code is visible.
- None of its corners are cut off.
- The camera can focus clearly.
- There isn’t excessive glare.
- The QR code is large enough for the webcam to recognize.
You don’t need to take a picture. Camera should automatically detect the code once it is clearly visible.
Step 4: Open the Detected Wi-Fi Link
Once the QR code has been recognized, a link should appear in the Camera app.
Click the detected link.
Windows will open Settings with the network information contained in the QR code.
Step 5: Add and Connect to the Network
Check that the Wi-Fi network shown is the network you intended to join.
Confirm that you want Windows to add and connect to the Wi-Fi network.
You can also choose whether Windows should automatically connect to this network whenever it is within range.
That’s it. You have connected your Windows PC to Wi-Fi using a QR code without manually typing the Wi-Fi password.
Method 2: Use a Wi-Fi QR Code Scanner App
Another way to connect to Wi-Fi with a QR code is to use a dedicated QR scanner app.
This method is especially useful if the built-in Camera method isn’t available, you’re using Windows 10, or you want additional features such as scanning QR codes stored as image files.
One option is a Wi-Fi QR Code Scanner available through the Microsoft Store. Dedicated Wi-Fi QR scanner apps may be able to scan Wi-Fi codes with your webcam, read saved QR-code images, generate Wi-Fi QR codes, and display previously stored Wi-Fi profiles.
Step 1: Open Microsoft Store
Press the Windows key and search for:
Microsoft Store
Open it.
Search for:
Wi-Fi QR Code Scanner
Before installing any third-party application, check its publisher, recent reviews, permissions, and privacy information.
Step 2: Install and Open the Scanner
Select the QR scanner you want to use and install it.
Once installed, open the app.
If it asks for permission to access your camera, grant the permission if you intend to scan the QR code using your webcam.
Step 3: Select Scan Code
Look for an option such as Scan Code.
The scanner should activate your laptop’s built-in webcam or connected external webcam.
If multiple cameras are connected, some scanner apps also allow you to select which camera you want to use.
Step 4: Scan the Wi-Fi QR Code
Display the Wi-Fi QR code on your smartphone, tablet, another PC, or printed card.
Place it in front of the webcam.
Keep the QR code steady until the app recognizes it.
Depending on the app, it may extract the:
SSID + security type + Wi-Fi password
and either provide a direct connection option or display the credentials.
If it doesn’t connect automatically, use the displayed network name and password to connect manually from Windows Wi-Fi settings.
Method 3: Scan a Saved Wi-Fi QR Code Image
A dedicated scanner becomes even more useful when the QR code is already stored on your Windows PC.
For example, someone may have sent you a Wi-Fi QR code through email, WhatsApp, Telegram, or another messaging service.
In that situation, you can’t conveniently point your laptop’s camera at its own display.
Instead, use a QR scanner that supports scanning from an image or file.
Step 1: Save the QR Code
Download the QR-code image to your PC.
Remember where you saved it, such as:
Downloads
or
Pictures
Step 2: Open Your QR Scanner
Launch a trusted QR-code scanner that supports reading QR codes from saved images.
Look for an option such as:
Scan Image
Open Image
Scan From File
or something similar.
Step 3: Select the QR-Code Image
Browse to the folder containing the saved QR code and select the image.
The scanner should decode the QR code.
For a Wi-Fi QR code, it may reveal information such as the network name, security type, and password.
Step 4: Connect to the Network
If the application provides a Connect option, you may be able to use it directly.
Otherwise, note or copy the Wi-Fi network name and password.
Then go to:
Settings > Network & internet > Wi-Fi
Select the appropriate Wi-Fi network, click Connect, and enter the password obtained from the QR code.
Be Careful With Online QR Scanners
You may also find websites that allow you to upload a QR-code image and decode it.
I don’t recommend uploading a private home or office Wi-Fi QR code to an unknown website.
Remember that the QR code may contain the actual Wi-Fi password. Treat a Wi-Fi QR-code image with the same care you would treat the password itself.
A reputable local app is generally a better option for sensitive Wi-Fi credentials.
Method 4: Scan the Wi-Fi QR Code With Your Phone and Connect Manually
If your Windows PC doesn’t have a webcam or you don’t want to install another application, your phone provides a simple workaround.
Most modern Android phones and iPhones can recognize Wi-Fi QR codes.
Step 1: Scan the QR Code
Open your phone’s Camera or built-in QR scanner and point it at the Wi-Fi QR code.
If the phone recognizes the code, it should identify the Wi-Fi network.
Depending on your phone, you may also be able to view or share the network information.
Step 2: Get the Wi-Fi Credentials
Note the Wi-Fi network name and password if they’re available.
You can now use those credentials on the Windows PC.
Step 3: Connect Your Windows PC
On Windows 11, go to:
Settings > Network & internet > Wi-Fi
Open the available Wi-Fi networks and select the network identified by the QR code.
Click Connect.
Enter the password and click Next.
Your Windows PC should now connect to the network.
How To Connect to Wi-Fi with a QR Code on Windows 10
Windows 10 deserves special attention here.
The newer Windows Wi-Fi QR workflow documented by Microsoft shouldn’t be assumed to work identically on every Windows 10 installation.
If you’re using Windows 10 and the Camera app doesn’t give you the required Wi-Fi QR connection option, use one of the alternative methods above.
The easiest choices are:
- Install a trusted Wi-Fi QR scanner from the Microsoft Store.
- Scan the QR code using your smartphone and enter the credentials manually.
- Decode a saved QR-code image with a trusted scanner and manually connect.
For example, after decoding the QR code, click the Network/Wi-Fi icon on the Windows 10 taskbar.
Select the Wi-Fi network and click Connect.
Enter the password obtained from the QR code and click Next.
Windows should connect and save the network for future use.
Microsoft ended regular Windows 10 support on October 14, 2025, so PCs that meet the Windows 11 requirements should be considered for an upgrade to continue receiving the latest Windows improvements and security updates.
What If Your PC Doesn’t Have a Camera?
A built-in webcam isn’t mandatory.
If you have a desktop PC without a camera, you have three practical choices.
Use an External Webcam
Connect a USB webcam to the PC.
Once Windows recognizes it, open the Camera app and use Barcode mode to scan the Wi-Fi QR code.
If you’re using a third-party QR scanner, look for an option that allows you to select the external camera.
Scan the Saved QR-Code Image
If you already have the QR code as an image, use a trusted QR scanner capable of decoding image files.
This doesn’t require a webcam.
Use Your Phone
Scan the Wi-Fi QR code with your phone, retrieve the network credentials, and enter them manually on Windows.
For most users without a webcam, this is the simplest solution.
How To Connect If the Wi-Fi Network Is Hidden
A Wi-Fi QR code can also contain details for a hidden network.
If your QR scanner successfully extracts the information but the Wi-Fi network doesn’t appear in the available network list, you may need to add it manually.
On Windows 11, go to:
Settings > Network & internet > Wi-Fi > Manage known networks
Select Add network.
Enter the network name (SSID), security type, and security key/password obtained from the QR code.
If necessary, enable the option to connect even when the network isn’t broadcasting its name.
Save the network and connect.
Wi-Fi QR Code Isn’t Scanning? Try These Fixes
If Windows doesn’t recognize the Wi-Fi QR code, there are several things worth checking before trying another method.
1. Make Sure You’re Using Barcode Mode
When using Windows Camera, don’t leave it in regular Photo or Video mode.
Open Camera and select the Barcode/QR code icon.
2. Check Camera Permissions
Press Windows + I and go to:
Privacy & security > Camera
Make sure Camera access is turned on and that the required applications have permission to use it.
If you’re on Windows 10, the wording and location of these privacy options may differ slightly.
3. Update the Camera App
Open Microsoft Store and check for app updates.
Install an available Camera update and try scanning again.
4. Check Windows Update
Go to:
Settings > Windows Update
and click Check for updates.
Keeping Windows and its Store apps current is particularly important if a feature described here doesn’t appear on your PC.
5. Increase the QR Code Size
Small QR codes can be difficult for low-resolution laptop webcams to recognize.
If the code is displayed on another phone or computer, enlarge it before scanning.
6. Increase Screen Brightness
If you’re scanning from a phone, increase the phone’s display brightness.
This can make the black and white portions of the QR code easier for the webcam to distinguish.
7. Adjust the Distance
Don’t hold the QR code directly against the camera.
Move it slowly closer and farther away until the camera can focus clearly on the entire code.
8. Avoid Glare
Bright reflections can obscure part of the QR code.
Tilt the phone or printed code slightly if necessary, while keeping the QR code as square to the camera as possible.
9. Clean the Webcam
A fingerprint or layer of dust over a small laptop webcam can significantly reduce image clarity.
Clean the lens gently and try again.
10. Make Sure the Whole QR Code Is Visible
Don’t cut off the corners or edges of the QR code.
The entire square should be visible in the Camera preview.
11. Check Whether the Wi-Fi Password Changed
Sometimes the QR code scans perfectly but Windows still can’t connect.
The QR code may simply be outdated.
If the network owner changed the Wi-Fi password after creating the QR code, the old code will still contain the previous credentials.
Ask for a newly generated QR code or the current password.
How To Manually Use the Information Inside a Wi-Fi QR Code
Sometimes a QR scanner successfully reads the code but doesn’t provide a Connect button.
You can still use the information.
A decoded Wi-Fi QR code may look something like:
WIFI:T:WPA;S:HomeWiFi;P:ExamplePassword;;
The important fields are:
S: Network name (SSID)
P: Wi-Fi password
T: Security type
If the scanner gives you these details, open:
Settings > Network & internet > Wi-Fi
Find the network matching the S value.
Click Connect.
When Windows asks for the network security key, enter the value shown after P.
Remember that Wi-Fi passwords are case-sensitive.
Can You Share Wi-Fi with a QR Code From Windows 11?
QR codes can also work in the opposite direction.
Instead of scanning a QR code with your Windows PC, you can display a QR code on Windows and let another device scan it.
On current Windows 11 versions, open:
Settings > Network & internet > Wi-Fi
Open your connected network’s Properties.
Find Wi-Fi network password and select Show.
Windows can display the password and a QR code for the network. Another compatible device can scan that QR code to connect.
For a previously saved network, go to:
Settings > Network & internet > Wi-Fi > Manage known networks
Select the network and look for Show next to the Wi-Fi network password.
This is particularly useful when you have a complicated Wi-Fi password and want to connect another phone, tablet, or computer without typing it manually.
Is It Safe to Connect to Wi-Fi Using a QR Code?
Using a Wi-Fi QR code doesn’t automatically make a network safe.
Only scan Wi-Fi QR codes from sources you trust.
This is particularly important in public places such as hotels, airports, cafes, and restaurants. If you’re unsure whether a QR code is legitimate, verify the official Wi-Fi network name with the business before connecting.
You should also treat the QR code for your home or office Wi-Fi as sensitive information because it may contain the network password.
Avoid posting screenshots of private Wi-Fi QR codes publicly or uploading them to unknown QR-decoding websites.

Current Windows 11 versions can display a QR code when you reveal a Wi-Fi network password from its properties. Other compatible devices can then scan the displayed code to connect.
Conclusion
Connecting to Wi-Fi with a QR code on Windows is now much easier, particularly on Windows 11.
The simplest method is to open the built-in Camera app, switch to Barcode mode, point your webcam at the Wi-Fi QR code, select the detected link, and confirm the connection in Windows Settings. This lets you join a compatible Wi-Fi network without manually entering its password.
A dedicated Wi-Fi QR scanner app is another useful option, especially on Windows 10 or when the QR code is already saved as an image on your PC. If you don’t have a webcam, you can also scan the code using your phone and manually enter the resulting network credentials on Windows.
If the QR code won’t scan, check the Camera permissions, QR-code size, lighting, camera focus, Windows updates, and whether the credentials stored in the QR code are still current.
Whichever method you choose, remember that a Wi-Fi QR code may contain the network password, so only scan and share codes from networks you trust.
