Using a QR code can be a hassle if you’re browsing from your Windows PC. You must grab your phone, open the camera, scan the code, then share the URL with your computer to continue. Are you aware that there’s a quicker way to go about this? Scanning QR codes on a laptop with one of the recommended methods in this guide is relatively easy.

1. QR Scanning With Windows Camera

Windows Camera is a native app that can be used to scan QR codes via your laptop’s camera. It can scan a QR code printed on a piece of paper, product packaging, a smartphone, tablet or TV screen.

Open the Windows Camera app by pressing the Win button, and typing “Camera” to initiate a quick search. Click the gear-shaped icon in the upper-left corner to open Settings.

Click on the Related Settings drop-down menu, and enable the Try out new experimental features toggle. Close the app, and restart it.


On the right of your Camera app screen, Select the QR code scanning option to the right of your Camera app screen. (It looks like a bar code inside a circle.) Move the target QR code within the camera focus area. Scanning it will lead to an external website, landing page, email, or social media handle.

Along with scanning QR codes on a laptop in Windows, you can also scan QR codes from an image on a mobile device.

2. Google Lens in a Chrome Browser

You can use the Google Chrome browser’s built-in Google Lens feature to scan any QR code on a browser page and get instant results about its contents. It’s one of the best ways to scan a QR code on your computer without a camera.

Right-click the QR code, and choose Search images with Google. You will be prompted to select an area to search with Lens. Drag your mouse or trackpad near the bar code, and select its outer borders.

Troubleshooting Tips for QR Code Scanning on a Laptop

As we may know by experience, a laptop isn’t ideally suited for scanning QR codes. It is heavier to move around, and the camera resolution often tops out at 720p, which leads to several kinds of QR code scanner problems. Read through these tips for each of these scenarios:

  • QR code is too big or small: if the QR code is displayed on a cutout or billboard, you may not be able to picture the entire image on a laptop screen. Likewise, if it’s too tiny, you may not be able to capture it on your laptop camera, as it doesn’t have a Zoom feature. It would be better to take a photo of the QR code and upload the file manually on a laptop.
  • QR code is blurry/not clear: move to well-lit surroundings. You also need sufficient nits of screen brightness on your laptop screen.
  • Missing or broken links: if the URL connected to the QR code is not working properly, it may lead to a 404 error. The URL itself will need to be corrected.

To test any of these methods of scanning QR codes on Windows, you should know how to create your own QR code. Since Google Chrome has a built-in QR code generator, using it is the simplest option: right-click any page or image and choose Create QR Code. Additionally, there are numerous online QR generators available.
