Unlike phones, no version of macOS, Windows, or ChromeOS has a built-in QR scanner in a default camera app — so scanning a QR code on a computer takes one extra step, but it's the same step regardless of which desktop operating system you're using.
Quick Answer
Take a screenshot or save the QR code as an image, then upload it to an online QR decoder like the QR Code Scanner — it reads the code directly from the image file, so no camera or webcam is needed on Mac, PC, or Chromebook.
Why Desktops Can't Scan QR Codes Natively
Phones scan QR codes through the camera app because the camera is always pointed at the world in front of you. A laptop or desktop's webcam is typically pointed at your face during video calls, and none of the three major desktop operating systems ship a built-in "point the webcam at a QR code" feature the way iOS and Android do. That's why the reliable method on any computer is image-based, not camera-based.
How to Scan a QR Code on a Mac or MacBook
Take a screenshot of the QR code — press Shift + Command + 4, then drag to select just the code, or Shift + Command + 3 for a full-screen capture
Open the QR Code Scanner in Safari or Chrome
Upload the screenshot
The tool decodes the QR code and shows you the destination — a URL, WiFi network, contact card, or whatever it encodes
If you have an iPhone on iOS 16+ and a Mac on macOS Ventura or later, Continuity Camera is a live-camera alternative: open the Camera app on your iPhone, point it at the physical code, and a notification banner appears on your Mac that you can click to open in Safari. This only works with a physical code in front of your iPhone's camera, not for a code that's already an image on your Mac.
How to Scan a QR Code on a Windows PC
Take a screenshot with Windows key + Shift + S, then drag to select the code
Open the QR Code Scanner in your browser
Upload the screenshot (it's automatically copied to your clipboard after the snip, so you may be able to paste it directly depending on your browser)
Read the decoded result
How to Scan a QR Code on a Chromebook
Take a screenshot with Ctrl + Show Windows key (or Ctrl + F5), then select the code area
Open the QR Code Scanner
Upload the screenshot from your Files app or Downloads folder
Read the decoded result
The steps are identical to Mac and PC — only the screenshot shortcut changes, since the actual decoding happens in the browser regardless of operating system.
Scanning a QR Code That's Already Saved as a File
If the QR code arrived as an email attachment, a downloaded image, or a photo synced from your phone rather than something you need to screenshot, skip the screenshot step entirely — just upload the existing image file straight to the QR Code Scanner.

FAQ
How do I scan a QR code on a Mac or MacBook?
Take a screenshot or save the QR code image, then upload it to the QR Code Scanner — it reads the code directly from the image file, no camera needed. If you have a paired iPhone on iOS 16+, Continuity Camera is a live-camera alternative for codes physically in front of you.
Can you scan a QR code on a PC or Chromebook?
Yes — take a screenshot with your OS's screenshot shortcut, then upload it to an online decoder. This works the same way regardless of operating system, since the decoding happens on the image file, not through a camera.
How do I scan a QR code without a camera?
Save or screenshot the QR code as an image, then upload it to an online QR decoder such as the QR Code Scanner. The tool reads the pattern directly from the image pixels, so it works identically on desktop or mobile even without camera access.
Can you scan a QR code on a laptop?
Yes, the same way as a desktop Mac or PC — take a screenshot of the code, then upload it to a QR decoder. Laptop webcams aren't set up for QR scanning the way phone cameras are.
Why can't my Mac's camera scan a QR code directly?
macOS doesn't include a built-in camera-based QR scanner the way iOS does — the FaceTime camera on Mac laptops isn't paired with any system feature that detects QR codes. The screenshot-and-upload method is the reliable workaround on any Mac.
