WiFi QR Scanner
Point your camera at a Wi-Fi QR code, or upload a photo of one, to reveal the network name, password, and security type - decoded entirely in your browser, never uploaded.
Scan a code
Scan the Wi-Fi sharing code from another phone or router sticker to reveal the network name and password. Nothing is uploaded - decoding is local.
About WiFi QR Scanner
A Wi-Fi QR code is not an image of your password - it is a short line of text encoded in a QR square. The format is standardized: WIFI:S:<network name>;T:<WPA|WEP|nopass>;P:<password>;H:<true|false>;; where S is the SSID, T is the security type, P is the password, and H marks whether the network is hidden. This scanner reads that string and splits it back into readable fields, so you can see exactly what a code contains instead of just connecting blindly.
You can decode a code two ways. Click Start camera scan to use your device's rear-facing camera and hold the code - a router sticker, a printed guest-Wi-Fi card, or another phone's built-in share screen - in front of the lens; the scanner reads frames continuously and stops the moment it finds a valid code. If you already have a screenshot or photo, choose Upload an image instead and the same decoder reads it directly. The tool correctly handles escaped characters, so passwords containing semicolons, colons, commas, or backslashes come back intact.
Because a Wi-Fi password is sensitive, decoding runs 100% client-side using the open-source jsQR library. The camera frames and the image you pick are processed in the page itself and are never transmitted to a server - there is nothing to upload and nothing logged. On a European, self-hosted platform with no third-party trackers, the decoded SSID and password stay on your device.
If the scanner reads a QR code that is not a Wi-Fi code - a URL, plain text, or a different payload - it tells you so and still shows the raw decoded content, so you always know what the square actually held. Open networks with no password are reported as such, and hidden networks are flagged clearly.
How to use it
- 1Click Start camera scan and allow camera access, then hold the Wi-Fi QR code (from a router label or another phone's Share Wi-Fi screen) steady in the frame; or click Upload an image to pick a photo or screenshot instead.
- 2Let the scanner detect the code - it reads continuously and stops automatically on the first valid match, so no shutter button is needed.
- 3Read the decoded results: network name (SSID), password in plain text, security type (for example WPA), and whether the network is hidden.
- 4Copy the password to connect a new device manually, or note the details for your records.
- 5If the result says the code is not a Wi-Fi code, check the raw content shown - it means the QR encodes something other than a WIFI: payload.
Common use cases
- -Recover a forgotten Wi-Fi password from the QR code printed on a router label or a saved sticker.
- -Read the credentials from another phone's Wi-Fi share code without typing a long password into a new device.
- -Verify what a guest or office Wi-Fi QR actually contains before you print, laminate, or hand it out.
- -Check the encoded security type - WPA versus an open network - before trusting a QR posted in a public space.
- -Decode a QR from a screenshot or photo when the physical code is not in front of you.
Frequently asked questions
- What information does a Wi-Fi QR code contain?
- A Wi-Fi QR code encodes a plain-text string in the format WIFI:S:<name>;T:<WPA|WEP|nopass>;P:<password>;H:<true|false>;; - the network name (SSID), the password, the security type, and whether the network is hidden. This scanner decodes that string and displays each field separately.
- Is it safe to scan a Wi-Fi QR code here, and where does my password go?
- Yes. Decoding runs entirely in your browser using your device's camera or an image you choose; the photo and the decoded password never leave your device and are not sent to any server. There is nothing to upload and nothing stored.
- How do I find my Wi-Fi password from a QR code?
- Scan the QR code printed on your router label or generated by your phone's Share Wi-Fi feature, and the tool extracts the password field (P) and shows it in plain text so you can read or copy it.
- Can I decode a Wi-Fi QR code from a screenshot or photo?
- Yes. Use the Upload an image option to select a photo or screenshot of the code; the same in-browser decoder reads it, so you do not need the physical code in front of your camera.
- Why does it say the code is not a Wi-Fi code?
- The scanner recognized a QR code, but its content did not begin with the WIFI: prefix, so it encodes something else such as a URL or plain text. The raw decoded text is still displayed so you can see what it holds.
- Which camera does it use on a phone?
- It requests the rear (environment-facing) camera by default, which is best for pointing at a sticker or another screen. If the camera cannot be accessed, you can fall back to uploading an image.
