Last 10 scansWhat is a WiFi QR code?
A WiFi QR code is a QR code that encodes a network's login details — its name (SSID), password and security type — instead of a link or plain text. Routers, cafes and offices print one so guests can join the network by scanning instead of typing a password. This WiFi QR Code Scanner reads that code and hands back each field as copyable text.
How to scan a WiFi QR code online
- Pick an input. Use Camera to scan the code printed on the router or table card, or Image, Paste and URL for a photo or screenshot of it.
- Let it read the code. The camera decodes continuously, and an uploaded image is decoded the moment it lands. A router sticker in a dim closet or back room is common enough that the camera includes a flashlight toggle and pinch-to-zoom for it, alongside a front/back camera switch, when your device supports them.
- Copy the details. The network name, password and security type each get their own row with a copy button, so you never have to type a long password by hand.
Using it as a laptop or Windows WiFi QR code scanner
A phone's camera isn't the only way in — this is a laptop WiFi QR code scanner too, since every input runs in the browser rather than a phone-only app. On a Windows WiFi QR code scanner setup with a webcam, Camera mode works exactly like it does on a phone. Without a webcam, take a photo of the code on another device and open it here with Image mode, or take a screenshot and press Ctrl+V to decode it straight from the clipboard — no file to save first. The same page works the same way on Windows, macOS, Chromebooks and Linux, since nothing needs to be installed.
What this scanner reads from a WiFi code
- Network name (SSID) — copyable in one tap
- Password — copyable, never uploaded
- Security type — WPA/WPA2, WEP, or open
Save, export or reissue the network's code
Past the copy buttons, a scanned WiFi code can be downloaded as a plain .txt file for a records folder, and the last 10 scans stay in a local history you can revisit or export as JSON or CSV. If the network's password ever changes, Edit QR Code sends the scanned SSID and security type straight to the QR code generator, pre-filled, so you can swap in the new password and print a fresh code for guests instead of typing it out by hand.
Is it free, and does it keep the password private?
Yes to both. This WiFi QR code scanner online free tool has no sign-up, no watermark, and no scan limit. Decoding runs entirely in JavaScript on your own device, so the network password never travels to a server — not to us, not to an app maker. A minimal set of ads keeps the site running without getting in the way of the scanner.
Frequently asked questions
Is this WiFi QR code scanner free?
Yes. Every scan is free and unlimited, with no account and no watermark. The site is supported by ads.
Is the WiFi password sent to a server?
No. Decoding happens entirely in your browser using JavaScript. The image, the camera frames, and the network name and password are never sent anywhere.
What does it show me from a WiFi QR code?
The network name (SSID), the password and the security type (WPA/WPA2, WEP, or open), each shown as its own field with a copy button.
The WiFi code won't scan. What now?
Switch to Image mode and upload a photo of it instead. The image path runs fifteen fallback passes — resizing, sharpening, thresholding, cropping and rotating — plus a second decode engine, which catches codes a live camera misses.
Can I connect straight from the result?
Copy the SSID and password with one tap each, then join the network from your device's WiFi settings — some phones also offer a direct "Join" action from a scanned WiFi code.
Does it work on a phone?
Yes. The layout adapts to small screens and the camera uses the rear lens by default, so it works the same way a scanner app would.
The router sticker is too dark to scan. Any way around that?
Tap the flashlight icon in Camera mode if your device supports it, or switch to Image mode and take a photo with your phone's own camera (which usually has a better flash) and upload that instead.
Can I reissue the code with a new password?
Yes. Scan the old code, then tap Edit QR Code — it opens the QR code generator with the network name and security type already filled in, so you only need to type the new password before downloading a fresh code.
