关于此工具
Got a QR code in a screenshot, a photo or on a screen in front of you? Drop the image here, paste it with Ctrl+V, or scan live with your camera. The content appears instantly.
Knows what's inside
Links get an Open button, Wi-Fi codes show the network name and password (with a copy button), contact cards show the name, phone and email, and payment codes are recognised too.
Safe scanning
Links are never opened automatically: check the address first, especially for codes from unknown sources. Everything runs in your browser: nothing is uploaded, stored or tracked. Want to make your own code? Use the QR code generator.

常见问题
How do I scan a QR code from a screenshot?
Take the screenshot, then press Ctrl+V on this page (or drop the image). The code is read immediately, no camera needed.
Can I scan a QR code with my laptop camera?
Yes. Choose 'With camera', allow access, and hold the code in the frame. It is detected automatically.
How do I see a Wi-Fi password from a QR code?
Scan the Wi-Fi QR code: the network name, security type and password are shown, with a button to copy the password.
Is it safe?
The scan happens on your device and links are never opened automatically, so you can check a link before visiting it.
