You've received a QR code via WhatsApp, email, or a screenshot — but you can't point your phone camera at your own screen to scan it. Sound familiar? This is one of the most common frustrations for smartphone and PC users. The good news: scanning a QR code from a saved image is easy once you know the right method for your device.
This guide covers every scenario: Android, iPhone, Windows PC, Mac — with clear step-by-step instructions for each.
Method 1: Free Online QR Scanner — Works on All Devices
This is the fastest and most universal method — it works on every device without installing any app:
- Open your browser and go to qrking.in/qr-scanner.html.
- Click the "Upload Image" area, or drag and drop your QR code image directly onto the page.
- The tool instantly decodes the QR code and displays the full text or URL.
- If it contains a URL, click "Open Link" to visit it safely — or copy the text.
Your image is never uploaded to any server. All processing happens inside your browser via JavaScript — your data is 100% private.

Method 4: Scan QR Code from Image on PC or Mac
This is the most common desktop use case — you've saved or screenshotted a QR code and need to decode it without a phone:
- Visit qrking.in/qr-scanner.html in any browser (Chrome, Firefox, Edge, Safari).
- Click the "Click or Drag & Drop Image Here" area.
- Browse to your QR code image file (PNG, JPG, screenshot) and select it.
- The decoded text or URL appears instantly in the results panel on the right.
Pro tip: You can also drag an image file directly from your Desktop or File Explorer onto the upload zone — no clicking needed.
Method 5: Scan a WhatsApp or Email QR Code Screenshot
A very common scenario — someone shares a payment QR, event ticket, or coupon code via WhatsApp, and you need to decode it on your phone:
- Long-press the image in WhatsApp — some Android builds show a "Scan QR code" option directly.
- If not, save the image to gallery and use Google Lens (Android) or Google app (iPhone).
- Or simply upload it to our online QR scanner — it works on mobile browsers too.
Is It Safe to Scan QR Codes from Saved Images?
QR codes are just data containers — scanning them is safe. The risk lies in clicking the decoded URL without first checking where it leads. Our scanner always shows you the raw text/URL before you open it, so you can verify the destination. This is critical when dealing with QR codes from unknown senders.

Frequently Asked Questions
Can I scan a QR code from a PDF?
Yes. Take a screenshot of the PDF page containing the QR code (Win+Shift+S on Windows, Cmd+Shift+4 on Mac), then upload that screenshot to our online scanner. Works perfectly.
Why isn't the QR code being detected from my image?
Common causes: the QR code is too small or blurry, poor contrast, partially cropped, or at a severe angle. Try a higher-resolution crop of just the QR code area. Our scanner also handles inverted (white-on-black) QR codes automatically.
Does it work on Chromebook?
Absolutely. Visit qrking.in/qr-scanner.html in Chrome and upload your image — it works exactly like on Windows or Mac. No extensions needed.
