QR Code Scanner

Scan QR codes with your camera or from an image file: decoded entirely in your browser.

Scan image file

Decoding runs entirely in your browser with jsQR (MIT): nothing is uploaded, and the camera stream stops the moment a code is found. Camera access requires HTTPS or localhost. WiFi, link, email, and contact codes are parsed and shown as readable cards so you can act on them instantly.

Frequently Asked Questions

>Is my camera feed sent anywhere??

No. The video frames are decoded locally with jsQR in your browser. Nothing is uploaded, and the camera stream stops as soon as a code is found or you stop it.

>Why does the camera not start??

Camera access requires HTTPS or localhost, and you must grant the permission prompt. If a popup was blocked, click Start camera again.

>Can I scan a code from a screenshot??

Yes: use the Scan image file button to decode any PNG, JPEG, or WebP image, including screenshots in any orientation.
