Upload a photo or screenshot of a WiFi QR code and get the network name, password and security type back. The image is decoded on your device and never leaves it.
🔒 Your image never leaves your device — the code is read in your browser.
Add the QR code
Upload a photo or screenshot of the code, or take a picture with your camera.
Let it decode
The code is read in your browser. Difficult photos are retried automatically with contrast and threshold adjustments.
Read the details
The network name, password, security type and whether the network is hidden are all shown.
Copy the password
Tap copy and paste it wherever you need it. Nothing is stored once you close the tab.
A WiFi QR code holds no magic — it is a short piece of text written in a specific pattern that phone cameras recognise. It looks like WIFI:T:WPA;S:MyNetwork;P:mypassword;; where T is the security type, S is the network name and P is the password. The double semicolon at the end marks the end of the payload. That is the whole format.
Because it cannot be. The QR code has to hand the password to a phone that has never seen the network before, so the password travels in the code as plain text. Anyone who can photograph the code can read it — which is worth remembering before pinning a WiFi card somewhere public. A guest network is the right answer to that problem, not a hidden password.
If the network name or password contains a semicolon, colon, comma, quote or backslash, those characters are written with a backslash in front so they are not mistaken for field separators. A reader that ignores this returns a truncated password — one of the most common reasons a decoded password does not work. This tool unescapes them properly, so what you see is what was stored.
Decoding a QR from a real photograph is harder than from a clean screenshot: glare across the code, a steep angle, poor lighting or camera shake all defeat it. This tool retries automatically with several image treatments — rescaling, contrast stretching and automatic thresholding — before giving up, which recovers most difficult photos. If it still fails, get closer so the code fills the frame and avoid reflections.
How do I get the WiFi password from a QR code?
Upload a photo or screenshot of the code here. A WiFi QR code stores the password as plain text inside the code, so reading the code gives you the password directly — no cracking and no guessing involved.
Is the WiFi password stored in the QR code itself?
Yes, in plain text. The code has to give the password to a phone that has never joined the network, so there is nowhere to hide it. That is also why a printed WiFi card in a public place effectively publishes the password to anyone who can photograph it.
Is my image uploaded to a server?
No. The image is decoded entirely in your browser and never sent anywhere. Nothing is stored, and closing the tab discards everything.
The QR code will not read. What can I do?
Get closer so the code fills more of the frame rather than zooming, avoid reflections by tilting slightly instead of shooting straight at a screen, keep the white border around the code in shot, and hold the camera steady. This tool already retries with rescaling, contrast stretching and automatic thresholding, so a sharper photo is usually all that is missing.
It says the code is not a WiFi code — what does that mean?
The code was read successfully but contains something else: a web address, contact card, payment link or plain text. The raw contents are shown so you can see exactly what it holds.
Can I read a QR code from a screenshot?
Yes, and screenshots usually work better than photographs because there is no glare, no angle and no motion blur. If you can screenshot the code rather than photograph it, do that.
