How to Scan a QR Code from an Image — Complete Guide

Whether you have a QR code in a WhatsApp screenshot, an email attachment, a PDF, or a saved photo, this free online scanner can read it instantly. Here's how to use it on any device:

Scanning from PC or Mac (Upload Method)

  1. Save the QR code image to your computer (right-click → Save Image As, or take a screenshot with Win+Shift+S / Cmd+Shift+4).
  2. Click the "Click or Drag & Drop Image Here" area above, or drag the image directly onto it.
  3. The decoded text, URL, or data appears instantly in the results panel.
  4. If it's a URL, click "Open Link" to navigate safely.

Scanning with Your Phone Camera (Live Scan)

  1. Switch to the "Use Camera" tab above and tap "Start Camera".
  2. Grant the browser permission to access your camera when prompted.
  3. Point your camera at any QR code — physical or on another screen.
  4. The QR code is detected and decoded automatically in real time.

Scanning from a WhatsApp or Screenshot Image (Mobile)

  1. Open this page in your mobile browser (Chrome, Safari, Firefox).
  2. Tap "Upload Image" and select the saved image from your gallery or Camera Roll.
  3. The QR code contents are decoded instantly without leaving the page.

What Types of QR Codes Can This Scanner Read?

This scanner reads all standard QR code types:

  • URLs & websites — Opens with a direct "Open Link" button
  • WiFi credentials — Shows network name, password, and security type
  • vCard contacts — Displays contact info ready to save
  • UPI payment codes — Decodes UPI ID and payee details
  • Phone numbers, SMS, email — Click to call, message, or email
  • Plain text — Copy with one click

Is This QR Scanner Completely Private?

Yes — 100%. This scanner operates entirely inside your web browser using JavaScript. Your image is never sent to any server. The image data is processed on your own device (CPU) and discarded when you close the tab. There is no account required and nothing is stored or logged. This approach makes it one of the safest QR code scanners available online.

Why Can't I Just Use My Camera on My PC?

Standard PC/laptop cameras cannot scan QR codes that are displayed on the same screen. The best solution for PC users is to upload the QR image file directly using the tool above. For QR codes on a second screen or physical document, the camera tab works — simply allow camera access when your browser prompts you.

Frequently Asked Questions

Can I scan QR codes from a PDF?

Yes. Take a screenshot of the PDF page (Win+Shift+S on Windows, Cmd+Shift+4 on Mac), then upload that screenshot here. The tool handles standard image formats including screenshots of PDF pages.

My QR code isn't being detected — what should I do?

Try these fixes: ensure the QR code is fully visible and not cropped; use a higher-resolution image; crop the image to focus on just the QR code area before uploading. Our scanner also handles inverted (light-on-dark) QR codes automatically.

Does it work on iPhone and Android?

Yes. This scanner works in any modern mobile browser — Chrome on Android, Safari on iPhone. Upload images from your gallery using the Upload tab, or use the Camera tab for live scanning.

Can I scan a QR code from another website or app?

Yes. Take a screenshot of the screen showing the QR code (on Windows: Win+Shift+S; on Mac: Cmd+Shift+4; on Android: Power+Volume Down; on iPhone: Power+Volume Up), then upload that screenshot here.
