You pulled up a QR code on your laptop screen or got a screenshot sent to you — but your phone is across the room. You just need to know what the QR code says.
Here's how to scan it in seconds, entirely in your browser: QR Code Scanner.
No app install. No upload to a server. No account.
Two Ways to Scan
1. Upload an Image
If you have the QR code as a PNG, JPG, or screenshot:
- Open the QR Code Scanner
- Click Upload Image and select your file
- The decoded text appears instantly
Works with any QR code image — screenshots, photos, files from email.
2. Use Your Webcam
If the QR code is displayed on a physical object or another screen nearby:
- Open the QR Code Scanner
- Click Start Camera
- Point your webcam at the QR code
- The result appears the moment the code is detected
The camera feed is processed locally — frames never leave your browser.
What Can QR Codes Contain?
QR codes can encode many types of data:
| QR Content | What You'll See |
|---|---|
| Website URL | A clickable link |
| Plain text | The raw text string |
| WiFi credentials | SSID + password |
| Contact info (vCard) | Name, phone, email |
| Email address |
mailto: link |
| Phone number |
tel: number |
The scanner decodes whatever is embedded — you'll see the raw output and can copy it with one click.
Common Use Cases
Working from a laptop: A client sends you a QR code in a chat. Instead of grabbing your phone, paste the screenshot directly into the scanner.
Verifying a QR code you generated: After creating a QR code with the QR Code Generator, scan it to confirm it encodes the right data.
Checking a physical code: Hold a product box or flyer up to your webcam — the scanner reads it live.
Debugging dynamic QR codes: If a QR code is redirecting to the wrong URL, scanning it shows you exactly what URL is embedded.
Privacy: How It Works
All scanning happens inside your browser using the jsQR library.
- Uploaded images are decoded client-side — they are not sent to any server
- Webcam frames are processed in-memory — no frames are stored or transmitted
- The decoded result stays on your screen only
There is no backend involved in the scanning step.
