Browser-Based QR Scanner

Scan a QR Code Online, From an Image or Your Camera

This scanner works in any modern browser on a phone, tablet or computer. Point your camera at a code, or upload, drag in or paste a screenshot to read the link, text or Wi-Fi details it holds. There's nothing to install.

  • Runs in your browser: images and the camera feed are decoded on your device. We never upload them to our servers.
  • Reads screenshots and photos: upload a PNG or JPG, drag it onto the scanner, or paste it straight from your clipboard.
  • Works offline once installed: add it to your home screen and it keeps scanning without a signal.

How to Use the Online Scanner

1

Choose camera or image

Tap "Scan with camera" and allow camera access, or tap "Upload an image or screenshot".

2

Aim, or pick the file

Hold the code inside the bracket, or choose the screenshot. On a computer you can also drag the image in or paste it.

3

Open or copy the result

The result appears in your scan history, where you can open the link or copy the text.

How to Scan a QR Code on a Computer or Laptop

You don't need a phone. Get the code onto your screen as an image, then let this page read it.

  1. If the code is on your screen (in an email, PDF or web page), take a screenshot of just the code. On Windows, press Windows + Shift + S. On a Mac, press Command + Shift + 4 and drag around the code.
  2. Paste or upload it here. Press Ctrl+V (or Command+V on a Mac) on this page, drag the image onto the scanner, or click Upload.
  3. If the code is printed, click "Scan with camera" and hold the paper up to your webcam, about 6 to 10 in (15 to 25 cm) away, in good light.

The scanner needs the whole code in the image, including the blank border around it. If it can't find one, crop a little wider and try again. Still stuck? See why a QR code won't scan.

Frequently Asked Questions

Is this scanner safe to use?

Yes. The scanner processes everything in your browser, and we never send your camera feed or image files to our servers. Before installing any scanner app instead, check the permissions it asks for: reading a QR code only needs the camera. And whatever you scan with, check the link before you open it, especially if it asks you to log in or pay.

Can I scan a QR code from a screenshot or photo?

Yes. Tap "Upload an image or screenshot" and choose it from your photos or files. On a computer you can also drag the image onto the scanner or paste it with Ctrl+V (Command+V on a Mac). It works for QR codes on PDF tickets, emails and screenshots a friend sent you.

How do I scan a QR code on my laptop?

Screenshot the code (Windows + Shift + S on Windows, Command + Shift + 4 on a Mac), then paste it on this page. For a printed code, use "Scan with camera" and hold it up to your webcam.

Does it work on Android and iPhone?

Yes. It runs in any modern mobile browser, such as Safari on iPhone or Chrome on Android. Most recent phones can also scan straight from the built-in camera app; this page is handy when that doesn't work or the code is already in your photos.

How does the offline mode work?

The scanner is a Progressive Web App. Tap "Install App" in the scan history panel, or use your browser's "Add to Home Screen", to save it to your phone. Once saved, it opens and scans without a signal.

Pro Feature: Dynamic Content

Beyond Static: The Power of Dynamic QR Codes

Standard barcodes and static QR codes are permanent—once printed, the data cannot be changed. This creates massive waste if a link breaks or a destination changes.

With QRTRAC Dynamic QR Codes, you can edit the destination URL or content at any time, even AFTER they've been printed and distributed.

Zero Print Waste

Update menus, manuals, or marketing links instantly without reprinting.

Advanced Analytics

Track every scan: location, device type, and time of day in real-time.
