How to Scan a QR Code Without Installing an App
You do not need to download an ad-filled scanner app from an app store. Your iPhone or Android camera already has scanning built in, and you can scan from webcams or uploaded screenshots directly in your browser.
1. Scan in Your Browser with QR Here (Phone, PC & Mac)
The easiest and most versatile way to scan a QR code is directly in your web browser with our free QR Here Scanner. It runs 100% on your device with no app store downloads and zero data uploaded to servers.
Two Quick Ways to Scan on QR Here:
Option A: Live Camera or Webcam: Open QR Here in Chrome, Safari, Edge, or Firefox. Click Start Camera and allow camera access. Hold the code in front of your camera. Your link appears instantly.
Option B: From an Image or Screenshot: Take a screenshot or photo of the QR code. Switch to the Upload Image tab on QR Here. Drag and drop the file or tap to select it. The code is decoded in milliseconds.
2. Use the Built-In Camera on iPhone or iPad
Apple has built-in QR scanning right inside the standard camera:
- Open the default Camera app.
- Point your phone steadily at the QR code (no need to press the shutter button).
- A yellow link banner will appear below the code. Tap it to visit the page.
Quick Tip: If your iPhone does not detect the code, open Settings > Camera and verify that Scan QR Codes is turned on.
3. Use the Built-In Camera on Android
Almost every modern Android phone (Samsung, Google Pixel, Motorola, Xiaomi) scans QR codes out of the box:
- Open your phone's default Camera app.
- Hold it steady facing the QR code.
- Tap the pop-up link bubble to open it.
Alternative: If your camera app does not react, swipe down from the top of your screen to open Quick Settings and tap the Scan QR code tile, or tap the Google Lens icon in your search bar.
Why You Should Avoid Third-Party App Store Scanners
When you search "QR scanner" in the App Store or Google Play, you will see hundreds of utility apps. Here is why you should skip them:
- Annoying Video Ads: Most free scanner apps force you to watch unskippable 30-second ads before showing your link.
- Subscription Traps: Many apps trick users into weekly or monthly subscriptions for a feature your phone already does for free.
- Data Tracking: Third-party scanner apps often log your location, device ID, and every URL you scan to sell to advertisers.

Yes. With the QR Here web scanner, simply select the "Upload Image" tab and choose your screenshot or photo. It decodes the code instantly right inside your browser.
How do I scan a QR code on a computer?
Open the QR Here homepage on your laptop or desktop. You can either use your webcam to scan a physical code or upload an image file of the code to decode it immediately.
