About the QR Code Reader

Sometimes the QR code you need to read is already on your screen – in an e-mail, a PDF, a chat message or a screenshot – and pointing a phone at your own monitor is awkward. This tool reads QR codes from image files and pasted screenshots instead.

The image is decoded in your browser with the open-source jsQR library and never uploaded. Links are not opened automatically: the tool shows you the destination domain first, so you can spot a suspicious address before you visit it. Wi-Fi codes are split into network name, security type and password.

How to use it

  1. Click "Choose an image" or drag an image file onto the box. You can also copy a screenshot and press Ctrl+V (⌘+V on a Mac) on this page.
  2. Wait a moment while the image is scanned.
  3. Read the decoded text and copy it with the Copy button.
  4. For a link, check the domain shown under "Link to" before clicking "Open link". For a Wi-Fi code, copy the password or type it into your device.
  5. Click Clear to read another image.

Features

  • Images and screenshots: Reads PNG, JPG, WebP, GIF and BMP files up to 25 MB, and screenshots pasted from the clipboard.
  • Safe link preview: Only http and https links get an Open button, and the domain is shown prominently so you know where the link leads.
  • Wi-Fi details: Wi-Fi QR codes are split into network name, security type, password and hidden-network flag.
  • Robust scanning: Large photos are scanned at several sizes, and light-on-dark and transparent QR codes are supported.
  • No camera, no upload: The tool never asks for camera access, and the image stays on your device.

Examples

Checking a code before printing

Limitations and notes

  • Only one QR code per image is read. Crop the image if it contains several codes.
  • Very blurry, tiny, strongly distorted or partly hidden codes may not be found.
  • Other barcode types (EAN, Code 128, Data Matrix and so on) are not supported.
  • The tool reads image files; it does not use your camera.

Frequently asked questions

Is my image uploaded?

No. The image is opened and decoded by JavaScript in your browser. Nothing is sent to a server.

Is it safe to open the link from a QR code?

QR codes are a common way to hide phishing links. Check that the domain shown under "Link to" is the one you expect – look out for misspellings or extra words – before clicking "Open link".

Why was no QR code found?

The code may be too small, blurred, cut off or one of several codes in the image. Try a sharper photo, crop the image around a single code or take a larger screenshot.

Can I scan a QR code with my webcam?

Not with this tool. Take a photo or screenshot of the code and open the image file instead.
