How to Decode a WiFi QR Code Online
- Upload the image — drag and drop the QR code, use the file picker, or press Ctrl+V to paste a screenshot directly from your clipboard
- Wait one second — the decoder reads the QR automatically using two detection engines (ZXing and jsQR)
- Copy your credentials — the network name (SSID), password, and security type appear clearly with individual copy buttons
- Connect manually — open WiFi settings on your laptop, TV, console, or any other device and enter the credentials
No account. No app. No camera permission required.
WiFi QR codes let you share network access instantly but most devices only connect automatically without ever showing the password. This WiFi QR code decoder does the opposite. Upload a QR code image or paste a screenshot, and the tool reveals the exact network name, password, and security type stored inside.
Everything runs locally in your browser. No image is sent to any server. Nothing is stored.
How to Extract WiFi Password from a QR Code Screenshot
If someone sent you a WiFi QR code as an image, or you took a screenshot of a QR printed on a router or in a hotel room, you can decode it in seconds without any additional software.
On Windows: Press Print Screen or use Snipping Tool to capture the QR code. Then press Ctrl+V directly on this page to paste the screenshot no file saving needed.
On Android: Take a screenshot (Power + Volume Down). Open this page in Chrome and use the file picker to upload from your gallery. Or share the image and open it in this tool directly.
On iPhone / iPad: Take a screenshot (Side button + Volume Up). Open this page in Safari, tap the file picker, and choose your screenshot from Photos.
On Mac: Use Cmd+Shift+4 to select the QR area. The screenshot saves to your desktop. Drag and drop it onto the decoder above.
The tool supports JPG, PNG, and WebP. It attempts multiple image scales automatically, so even compressed or small QR codes have a high chance of being decoded correctly.
WiFi QR Code to Password Converter How It Works
A WiFi QR code is not an image you can read with your eyes. It is a machine-readable encoding of a standard text string that looks like this:
WIFI:T:WPA2;S:YourNetworkName;P:YourPassword;;Each field in that string means:
- T — Security type: WPA, WPA2, WPA3, WEP, or nopass (open network)
- S — Network name (SSID): the name that appears in your WiFi list
- P — Password: the exact passphrase to connect
- H — Hidden: true if the network does not broadcast its name publicly
This decoder reads that string and breaks it apart into readable fields. It is not guessing it extracts the exact values stored by whoever generated the QR code. The password shown is the real password, character for character.
Can I Scan a WiFi QR Code on a Laptop?
Yes — but not using your laptop’s built-in camera app, because Windows and macOS do not have a native WiFi QR connection feature. Unlike Android and iOS, desktop operating systems cannot read the WIFI: format and connect automatically.
This decoder fills that gap. Upload or paste the QR code image on your laptop, and within seconds you have the SSID and password ready to enter in your network settings.
Connecting on Windows 11 / Windows 10: Click the WiFi icon in the taskbar → select the network name from the list → click Connect → paste the password → click Next.
Connecting on macOS: Open System Settings → Wi-Fi → find the network name → click Connect → paste the password → click Join.
Connecting on Linux: Click the network icon in the top bar → select the network → enter the password → click Connect.
If the network does not appear in your list, it may be a hidden network. Choose “Connect to hidden network” and enter both the SSID and password manually.
Can You Decrypt a WiFi QR Code?
The word “decrypt” comes up often in search, so it is worth being precise. WiFi QR codes are not encrypted they encode network credentials in a plain text format that any compatible reader can decode instantly. There is no encryption key to break and no password-protected layer around the data.
What the decoder does is parse that structured text and present each field network name, password, security type in a readable format.
The security type (WPA2, WPA3, etc.) refers to how your device communicates with the router once connected, not to the QR code itself. So when people search for “decrypt WiFi QR code,” what they really need is a decoder that reads and displays the credential string which is exactly what this tool does.
Scan WiFi Password Online What This Tool Does
Most online QR scanners simply show you the raw text inside a QR code. This tool goes further for WiFi QR codes by parsing the result into structured fields separate boxes for network name, password, and security type with one-click copy buttons for each.
You do not need to understand the WIFI: format or manually extract the password from a long string. The tool does that automatically and presents the credentials in a clean, usable layout.
This is particularly useful when:
- You want to see the WiFi password without automatically connecting
- You are connecting a second device and need the credentials in text form
- You received a QR code from an IT team and want to verify the network name before joining
- You are on a laptop or desktop that cannot scan QR codes natively
Who Needs a WiFi QR Decoder
Laptop and desktop users — the most common use case. No desktop OS supports automatic WiFi connection from a QR code. This decoder gives you the credentials to enter manually.
People who want the password itself — if you connected once via QR but now need to type the password into a TV, printer, or second laptop, decoding the original QR is the cleanest way to recover it without accessing the router.
Older Android users — automatic WiFi QR connection requires Android 10 or later. On Android 8 or 9, the camera app will not offer a connect prompt. Decode the QR here and connect manually through WiFi settings.
IT administrators and support teams — verify exactly what credentials a QR code contains before distributing it, without having to connect a device.
Anyone checking an unknown QR code — if a QR code is labelled as WiFi but you are not sure what it contains, decode it first. If it shows a URL instead of WiFi credentials, use the Safe QR Scanner to inspect the link before opening.
Is This WiFi QR Decoder Safe?
There are two separate safety questions the tool itself, and the QR codes you decode.
Tool safety: All processing happens inside your browser. The image you paste or upload never leaves your device. No password, SSID, or image data is sent to Toolsque servers, stored in a database, or logged anywhere. You can verify this by opening your browser’s developer tools and checking the Network tab no outbound requests are made during decoding.
QR code safety: WiFi QR codes from your own router, a trusted business, or a friend are safe to decode and use. Be cautious with codes from unknown sources. If the decoded result is a URL rather than WiFi credentials, do not open it directly use the Safe QR Scanner to check the destination first. If the network name does not match what you expected, do not connect.

Frequently Asked Questions
Can I scan a WiFi QR code on a laptop? Yes. Laptops cannot connect automatically using QR codes, but this decoder extracts the credentials from the image so you can enter them manually in your WiFi settings. It works on Windows, macOS, and Linux in any modern browser Chrome, Firefox, Safari, or Edge.
How do I connect my laptop to WiFi using a QR code? Upload or paste the QR code image into the decoder. Once it extracts the SSID and password, open your laptop’s WiFi settings, select the network name from the list, and paste the password when prompted. On Windows use the taskbar WiFi icon. On Mac use System Settings → Wi-Fi.
Does this tool show the actual WiFi password? Yes. The password stored inside the QR code is displayed in plain text in a separate field with a copy button. Nothing is hidden or masked.
Can I extract a WiFi password from a screenshot on Android? Yes. Take a screenshot of the QR code on your Android device, open this page in Chrome, tap the file picker, and upload the screenshot from your gallery. The tool decodes it and shows the credentials instantly. This works on all Android versions including older ones that cannot connect automatically via QR.
Can I use this without installing an app? Yes. The tool runs entirely in your browser. No download, no installation, no account required.
Is there a difference between “decode” and “decrypt” for WiFi QR codes? Technically yes. WiFi QR codes are not encrypted the credentials are stored in a readable text format. Decoding means parsing that text into separate fields. There is nothing to decrypt. When people say “decrypt WiFi QR code,” they mean decode or extract the password, which is what this tool does.
Can I paste a screenshot instead of uploading a file? Yes. Press Ctrl+V anywhere on the page to paste an image from your clipboard. This works with screenshots from Snipping Tool, Print Screen, Mac screenshot shortcuts, or any screen capture method. No need to save the file first.
Does this work on older Android phones? Yes. Automatic WiFi connection via QR requires Android 10 or later. This decoder works on any Android version in a browser decode the QR here, then connect manually through your device’s WiFi settings.
What if the QR code contains a link instead of WiFi credentials? The decoded content will appear as a URL rather than WiFi fields. Do not open unknown links directly. Use the Safe QR Scanner to check where the link leads before clicking.
Does this work for hidden WiFi networks? Yes. If the QR code includes a hidden network flag, the decoder notes it clearly. When connecting, choose “Connect to hidden network” in your WiFi settings and enter the SSID manually since hidden networks do not appear in the standard list.
What image formats are supported? JPG, PNG, and WebP. Screenshots from Windows, macOS, Android, and iOS all work. Avoid heavily compressed images shared through messaging apps repeated JPEG compression can degrade QR codes below the readable threshold. Use the original screenshot where possible.
Does this work on Mac and Windows? Yes. Any modern browser on Windows 10, Windows 11, macOS, and Linux works. No OS-specific software or permissions are needed.
Will the decoded password still work after a router reset? Only if the router password has not changed. A WiFi QR code stores the credentials at the moment it was generated. If the password changed after the QR was created, the decoded password will be outdated. You need a new QR code generated with the current password.
Can I connect multiple devices after decoding once? Yes. Once you have the SSID and password, you can enter them manually on as many devices as you like laptops, TVs, game consoles, printers without decoding again.
What do WPA, WPA2, and WPA3 mean in the decoder results? These are WiFi security standards. WPA3 is the latest and most secure, common on routers made after 2022. WPA2 is the current standard on most home and business networks. WPA (original) is outdated. WEP is very old and considered insecure. If your result shows WEP or no security type, the network has weak or no encryption.
Why is the QR code not detected? Common causes: low image resolution, heavy JPEG compression, or a very small QR code inside a large image. Try uploading a higher-resolution version or zooming in before taking the screenshot. The tool tries multiple scales automatically, but a minimum level of image quality is required. Images shared through WhatsApp or Telegram are often compressed enough to make decoding fail use the original screenshot instead.
