About this tool

A QR code in a screenshot, in a PDF or right in front of you? Scan it with your phone or computer camera, or simply drop the image. The scanner shows its content in plain text: a link with its domain, a Wi-Fi network name and password, a contact card or text, each ready to copy.

When to use it

Read a QR code from a screenshot

A QR code in a message or PDF can't be scanned by the phone displaying it: drop the screenshot here.

Get a Wi-Fi password

The network name and password are shown in plain text, ready to copy on a computer.

Check a QR code before opening it

The link's domain is shown before anything opens: useful against fake QR codes stuck on parking meters or posters.

How to use

  1. Click “Scan with camera” and allow access, or drop an image.
  2. Place the QR code inside the frame.
  3. Read the content: type, link domain, detailed fields.
  4. Copy the content or open the link after checking its domain.

How it works

The scanner uses the browser's built-in barcode detector when available (Chrome on Android and macOS). Elsewhere, it uses the jsQR library (Apache 2.0 license), loaded only on this page.

The content is then analyzed to recognize common formats: web addresses, Wi-Fi networks (WIFI:), emails (mailto:), phone numbers, SMS, locations (geo:) and vCards. The camera and images stay in your browser.

Tips for best results

  • Move closer until the code fills the frame, with no glare.
  • For a QR code on a screen, lower the brightness if the camera can't read it.
  • Be wary of QR codes stuck over another one in public places: always check the domain.
  • To create a QR code, use ZanaKit's QR code generator.

Common problems and fixes

The camera won't open

Allow camera access in your browser, then make sure no other app is using it.

No QR code found in the image

Crop the image around the code, or take a sharper, better-lit photo.

The link won't open

Some QR codes contain text rather than a link: copy the full content to see what it holds.
