QR Code Reader (Image)

About

This utility enables users to scan and decode QR codes from uploaded image files directly within their browser. It leverages the `jsQR` JavaScript library, a robust client-side QR code reader. The process involves loading the image onto an HTML5 `<canvas>` element, from which the pixel data is extracted. The `jsQR` library then analyzes this pixel data to detect and decode any QR codes present. This client-side implementation ensures user privacy, as image data is never transmitted to a server. The tool provides instant decoding results, displaying the extracted data and visually highlighting the detected QR code within the image. It's an efficient and secure solution for extracting information embedded in QR codes from static image files.
