# QR scanning on Windows

> Windows has no system-wide QR scanner, but recent versions of the built-in Camera app include a barcode mode that reads QR codes from the webcam. For screenshots (the common case on a desktop) upload the image to a browser-based scanner, which decodes it locally without installing anything.

## The two cases, and the right tool for each

QR codes reach a Windows PC in two forms: **on the screen** (emails, PDFs, web pages,
video calls) and **on paper** in front of you. Windows handles the second natively and
the first not at all, so you need both flows.

## On-screen codes: snip, then decode

The built-in Camera app cannot open image files, so for anything on your display the
screenshot route is the whole answer:

1. Press **Win+Shift+S** and drag across the code, the snip lands in your clipboard.
2. **Paste it** into a [browser-based scanner](/scan), or save and drag the file in.
3. Read the decoded text, then open it if the destination looks right.

The scanner runs client-side: decoding happens in the browser, the image never leaves
the machine, and you see the raw text before anything opens, the safe order of
operations for [unexpected codes](/docs/security/how-to-check-a-qr-code-before-opening).
Precise cropping is unnecessary; decoders find a code inside a larger screenshot on
their own.

## Paper codes: the Camera app or the webcam

Recent versions of the **Windows Camera app** include a **barcode mode** that reads QR
codes live from the webcam: open Camera, switch to the barcode option, and hold the code
up to the lens. If your build of the app lacks the mode (availability has varied across
Windows 10 and 11 versions) the same [browser scanner](/scan) has a webcam option that
behaves identically and needs nothing installed. Hold the code **15–30 cm** from the
lens, steady, with the light behind the camera rather than behind the code; more
webcam-specific technique is on the
[webcam scanning page](/docs/scanning/qr-scanning-with-a-webcam).

One habit worth avoiding: downloading a "QR reader" utility from a search result. The
category is dense with ad-stuffed and occasionally hostile software, and it solves
nothing the two flows above do not: the reasoning is the same as
[why phones stopped needing scanner apps](/docs/scanning/do-you-need-a-qr-scanner-app).

## Scanning at volume

If you are decoding codes all day (goods-in, ticketing, asset checks) a **USB 2D
imager** is the correct tool: it plugs in as a keyboard, needs no driver, and types each
decoded payload into whatever field has focus. Details and buying guidance are on
[hardware barcode scanners and QR](/docs/scanning/hardware-barcode-scanners-and-qr),
with the batch workflow itself covered under
[batch scanning](/docs/scanning/batch-scanning-many-qr-codes).

## FAQ

### Does Windows have a built-in QR code scanner?
Partially. Recent versions of the Windows Camera app include a barcode mode that scans
QR codes from the webcam, but it cannot decode image files. For screenshots, use a
browser-based scanner.

### How do I scan a QR code on my screen in Windows?
Press Win+Shift+S, snip the code, and paste the image into a browser-based scanner. It
decodes locally in the browser and shows the destination text before you open the link.

### How do I scan a QR code with my laptop's webcam?
Open the Windows Camera app's barcode mode, or a browser-based scanner's webcam option,
and hold the code 15–30 cm from the lens. Keep it steady and make sure the code is lit
from the front.

### What is the best QR scanner to download for Windows?
For occasional scanning, none, the Camera app and browser-based scanners cover
everything without installation. For all-day scanning workloads, a USB 2D imager that
types results as a keyboard is the professional answer.
