How to Scan a QR Code on a Laptop or PC

Use your webcam, upload an image file, or use your phone as a bridge, all through your browser with QRScan.ph. No standalone app needed.

Scanning a QR code on a laptop or PC is straightforward once you know which method to use. You do not need any special software. QRScan.ph handles it entirely in your browser.

1

Use Your Laptop Webcam

If your laptop has a built-in webcam, you can use it to scan QR codes the same way you would with a phone camera:

  1. Open QRScan.ph in Chrome, Firefox, or Edge on your laptop.
  2. Open the scanner on scan QR code online and allow browser permission to access your webcam.
  3. Hold the physical QR code, printed on paper, a card, or a screen, in front of your webcam.
  4. Keep it steady and well-lit. The QR code will be detected and decoded automatically.

This is the fastest method if you have a printed QR code or a QR code displayed on another device.

Upload a QR Code Image

If the QR code is already saved on your computer as a file, use the image upload method on QRScan.ph:

  1. Open QRScan.ph in your browser.
  2. Use the image scanner and select the file from your computer.
  3. QRScan.ph reads the QR code in the image and shows the result immediately.
  4. Copy the link or text, or open it directly in your browser.

This works for screenshots, downloaded photos, email attachments, and other image files containing a QR code.

Use Your Phone as a Bridge

If the QR code is only on your laptop screen, use your phone to read it:

Open the Camera app on your phone and point it at the QR on your laptop screen

Tap the notification to open the link on your phone

Or screenshot the QR on your laptop, send it to your phone, and scan with QRScan.ph

Why Scanning on a Laptop Is Different

No built-in QR flow

Phones scan from the Camera app automatically. PCs and Macs typically do not, so a browser scanner fills the gap.

Windows & macOS

Neither ships with a unified "point webcam at QR" shortcut at the OS level like many phones do.

QRScan.ph stays local

Your webcam stream and uploads are decoded in the browser. Use either camera mode or upload, whichever fits your situation.

No camera?

Upload an image sent from another device, or bridge via your phone as described above.

Easiest Way: QRScan.ph in Your Browser

Open scan online for your webcam or upload from disk, whichever is faster on your laptop. Works on Windows and Mac.
