What is the QR Code Scanner?
This QR code scanner is a free online tool that reads QR codes without a smartphone camera app. Scan QR codes inside gallery photos, screenshots, or images received in chat apps by uploading, dragging & dropping, or simply pasting with Ctrl+V — and scan in real time with your PC webcam or phone camera too. It is especially handy for QR codes displayed on the very screen you are looking at, which are impossible to photograph with the same device.
Scanned content is automatically classified as a link, Wi-Fi network, contact (vCard), phone number, SMS, email, or location. For Wi-Fi QR codes you can copy just the password; links open safely in a new tab. Everything runs inside your browser — neither images nor camera frames are uploaded — and your scan history stays on your device.
Key Features
Scan QR from Image Files
Upload, drag & drop, or paste (Ctrl+V) gallery photos and screenshots — the QR code inside is located and decoded instantly.
Real-Time Camera Scan
Scan live with a PC webcam or phone camera. The camera stops automatically after detection, and front/rear switching is supported.
Automatic Content Detection
URLs, Wi-Fi, vCard contacts, phone, SMS, email, and geo coordinates are detected with matching action buttons (open, call, map).
Wi-Fi Password Copy
Wi-Fi sharing QR codes are split into network name and password so you can copy just the password with one click.
How to Use
- Choose a scan method — Pick Scan from Image or Scan with Camera at the top.
- Add an image — Upload, drag & drop, or Ctrl+V a QR image; or press Start Camera and point it at the code.
- Check the result — Once detected, the content appears with its type: link, Wi-Fi, contact, and more.
- Copy or open — Use the buttons to copy content, open links, copy Wi-Fi passwords, or place calls.
Use Cases
QR Codes on Your PC Screen
QR codes on webpages and documents are awkward to photograph. Take a screenshot and paste with Ctrl+V — the link opens right away.
QR in Received Photos
Check QR codes inside invitations, event posters, and flyers received via chat or email by uploading the saved image.
Join Shared Wi-Fi
Scan a café or office Wi-Fi sharing QR to reveal the network name and password, then copy and connect.
Verify Before Printing
Check that the QR code on your business card or poster leads to the intended address before distribution.

Scanning with Built-in Phone Features
| Method | How to scan | Image file scan |
|---|---|---|
| iPhone Camera | Point the camera; a link banner appears on top | Partially, via long-press in Photos |
| Galaxy Camera | Enable Scan QR codes in camera settings | Needs Bixby Vision in Gallery |
| Google Lens | Open Lens and point at the code | Supported from gallery |
| Chat apps | Built-in scanner in some apps | Mostly unsupported |
| This scanner | Start Camera in the camera tab | Upload, drag & drop, and paste all supported |
For QR codes displayed on your PC screen or already saved as image files, scanning by image here is the fastest route.
Fixing Failed Scans
| Symptom/Cause | Solution |
|---|---|
| Blurry or tiny image | Re-capture so the QR fills at least a quarter of the frame |
| Skewed or distorted code | Use a straight-on shot (slight tilt is auto-corrected) |
| Glare or shadows | Re-shoot from an angle without reflections |
| Camera won't start | Allow camera permission in the address bar; check HTTPS |
| Out-of-focus camera | Center the code and keep a 15–30cm distance |
| Damaged QR code | QR codes recover up to ~30% damage; beyond that they must be reissued |
Common QR codes (versions 1–10) are usually recognized instantly. Inverted (light-on-dark) codes are attempted as well.
Frequently Asked Questions
Can I scan a QR code from a saved photo or screenshot?
Yes — that's the core feature. In the Scan from Image tab, upload or drag & drop the picture, or on PC just take a screenshot and paste it with Ctrl+V. It's the easiest way to read a QR code shown on the very screen you're using, which a phone camera can't photograph.
Are my photos or camera feed uploaded to a server?
No. QR detection runs 100% inside your browser with JavaScript; neither images, video frames, nor results are sent anywhere. Once the page is loaded, scanning even works if your connection drops — it's fully client-side.
What happens when I scan a Wi-Fi QR code?
Wi-Fi sharing QR codes (WIFI: format) are split into network name (SSID), password, and security type. Use the copy-password button to grab just the password and paste it into your Wi-Fi settings. QR codes created by iPhone and Galaxy Wi-Fi sharing are both supported.
The camera won't turn on.
Your browser has most likely blocked camera access. Click the lock (or camera) icon in the address bar, set Camera to Allow, and retry. The camera may also fail to open if another app (e.g., a video call) is using it. If you can't use a camera at all, the image scan tab works without one.
What if the QR code isn't recognized?
Blurry images and tiny codes lower the detection rate. Re-capture with the QR code large and sharp, avoid glare, and shoot straight-on. QR codes include error correction so minor damage is recovered automatically, but codes with more than ~30% damage cannot be read.
How is this different from my phone's built-in camera scanning?
The built-in camera is quickest for physical QR codes in front of you. This scanner adds what the camera can't do: reading QR codes inside image files (screenshots, received photos, PC screens), webcam scanning on desktop, Wi-Fi password extraction, automatic content typing, and scan history. Use whichever fits the moment.
