You can't point your camera at your own screen. When a QR code arrives in an email, a chat, a PDF or a web page you're already looking at, you need to scan it from an image instead. Every phone can do this without an extra app, and on a computer you can do it in the browser.
The Fastest Way on Any Device
Take a screenshot of the code, open the free online QR code scanner, and tap Upload image. On a computer you can also drag the image onto the viewfinder. The image is read on your device and never uploaded, and the scanner shows the code’s content before you open anything.
On iPhone
- Take a screenshot (Side button + Volume Up), or save the image.
- Open it in Photos. On recent versions of iOS, Photos recognises the code: touch and hold it, or tap the Live Text button, and choose to open the link.
- If nothing appears, upload the screenshot to the online scanner instead.
On Android
- Take a screenshot (Power + Volume Down), or save the image.
- Open it in Google Photos and tap Lens. The link or text in the code appears, ready to tap.
- You can also open the Google app, tap the Lens icon and pick the image from your gallery. On phones with Circle to Search, long-press the navigation bar and circle the code.
On a Windows PC or Mac
- Take a screenshot: Win+Shift+S on Windows, or Cmd+Shift+4 on a Mac, and select just the code.
- Upload it: open the scanner and drag the screenshot onto the viewfinder. This is also the way to scan on a laptop with no webcam.
- Code on a web page in Chrome: right-click the image and choose the Google Lens search option. Lens reads the code in a side panel.
Scanning a QR Code Inside a PDF
Zoom in until the code is large and sharp, take a screenshot of just the code, then upload it. Screenshots of a zoomed-out page are often too small or too blurry to read.
If the Image Won’t Scan
- Keep the white border. Scanners need the blank margin (the quiet zone) around the code, so don’t crop right up to its edge.
- Use a sharper copy. Images re-sent through chat apps get compressed. Ask for the original, or zoom in and screenshot again.
- Make sure the whole code is visible, including all three corner squares.
- Check before you open. Read the link the scanner shows, and see QR code security risks for what to watch for.
Common Questions
Can I scan a QR code without an app?
Yes. Phones can read codes from images with Photos on iPhone or Google Lens on Android, and any device can use a browser-based scanner by uploading a screenshot.
How do I scan a QR code on my laptop?
Take a screenshot of the code (Win+Shift+S on Windows, Cmd+Shift+4 on a Mac) and upload it to an online QR scanner. If your laptop has a webcam, the scanner can use it too.
Is it safe to upload a QR code image to an online scanner?
With the OmniQR Hub scanner, yes: the image is decoded in your browser and never uploaded. Other online scanners may send your image to a server, so check before using them for private codes such as Wi-Fi or payment codes.
