Scan a WiFi QR Code from an Image to Get the Password

WiFi QR codes encode the network name (SSID), password, and encryption type. When you scan one with a phone camera, it auto-connects you. But if you have the QR code as an image and need to see the actual password text — to type it on a device that cannot scan QR codes, or to share it with someone — you need to decode the QR code into readable text.

Upload the WiFi QR code image to a free browser-based scanner, and the decoded output shows the network name, password, and encryption type in plain text you can copy.

How WiFi QR Codes Store Network Credentials

A WiFi QR code contains a specially formatted text string: WIFI:T:WPA;S:NetworkName;P:MyPassword;;

The fields are:

• T — encryption type (WPA, WPA2, WEP, or nopass for open networks)
• S — SSID (network name)
• P — password
• H — optional, "true" if the network is hidden

When you decode a WiFi QR code, the scanner displays this string. You can read the password directly from the decoded text. Some scanners parse the format and display each field separately, while others show the raw string — either way, the password is right there in the output.

Where WiFi QR Codes Show Up as Images

WiFi QR codes are everywhere, and they often end up as images rather than physical codes:

• Hotel welcome cards — photographed for later, then you need the password on your laptop
• Router sticker photos — someone photos the QR code on the router and texts it to you
• Airbnb/rental listings — hosts include WiFi QR codes in their listing photos or check-in guides
• Office WiFi cards — IT department emails a QR code image for the guest network
• Generated QR codes — you created a WiFi QR code with a QR code generator and need to verify the password is correct

In all these cases, you have the QR code as a saved image file but need the password as copyable text.

Decode a WiFi QR Code Step by Step

1. Open the QR Code Scanner in any browser.

2. Upload the image containing the WiFi QR code — drag and drop or click to browse.

3. The scanner detects the QR code and shows the decoded text. Look for the WIFI: prefix.

4. The password appears after P: in the decoded string. For example: WIFI:T:WPA;S:HomeNetwork;P:mypassword123;; — the password is mypassword123.

5. Click "Copy to Clipboard" to copy the full decoded string, then paste it and extract the password.

The scanner labels the content type as "WIFI" when it detects the WiFi format, making it easy to identify even if you have multiple QR codes to check.

Privacy: Your WiFi Password Never Leaves Your Device

WiFi passwords are sensitive. Anyone with your WiFi password can connect to your network. When you upload a WiFi QR code to an online scanner, you want to be sure the password is not being logged on a server somewhere.

Browser-based QR scanners that process images locally (client-side) never send the image or decoded text to any server. The decoding happens in your browser using built-in web technology. You can verify this by going offline after loading the scanner page — if it still decodes images, no server is involved.

Avoid online QR scanners that upload your image to a server for processing. Even if they claim the upload is temporary, you have no way to verify that your WiFi password was not logged.

Frequently Asked Questions

Can I see the WiFi password from a QR code?

Yes. QR codes for WiFi contain the password in plain text (encoded in the QR format). Decode the QR code with any scanner, and the password appears in the output after the P: field.

How do I scan a WiFi QR code from an image?

Upload the image to a browser-based QR scanner. The decoded text shows the network name (after S:), password (after P:), and encryption type (after T:).

Is it safe to decode WiFi QR codes online?

Only if the scanner processes images locally in your browser. If it uploads your image to a server, your WiFi password could be logged. Look for scanners that work offline after loading, which confirms no server processing.
