About QR Code Reader

Decode a QR code from an uploaded image, pasted screenshot or your camera, and review the content before opening any link.

The reader decodes content locally and always shows the result first. Links require an explicit action so an unfamiliar QR code cannot silently redirect you.

What the result contains

A separate result that scan QR codes from an image, clipboard or camera. The source remains unchanged in the current browser session.

Supported formats

  • PNG
  • JPG
  • WEBP
  • GIF

How to use QR Code Reader

  1. Choose a source file in a supported format (PNG, JPEG, WEBP, GIF) and confirm the displayed file details.
  2. Prepare the available controls for this practical goal: Check an unfamiliar QR code's destination before scanning it with a phone
  3. Run QR Code Reader and confirm that the new result matches the stated outcome before saving it.
  4. Check this known constraint before download: Recognition needs a sharp, well-lit image with the full code visible If needed, revise the settings and create another version from the retained source.
Practical example

Check an unfamiliar QR code's destination before scanning it with a phone. Use a representative source, compare the output with the original, and keep the version that meets the destination's requirements.

When to use QR Code Reader

  • Check an unfamiliar QR code's destination before scanning it with a phone
  • Read a QR code from a screenshot or saved image
  • Decode a code live using your device's camera

Important limitations

  • Recognition needs a sharp, well-lit image with the full code visible
  • Camera scanning requires explicit permission and does not start automatically

Troubleshooting QR Code Reader

The result is different from what you expected

Recognition needs a sharp, well-lit image with the full code visible Return to the retained source, adjust the relevant setting and create a fresh result rather than repeatedly processing the output.
