How QR Code & Barcode Scanner works

This tool uses the open-source html5-qrcode library to detect and decode 1D and 2D barcodes from static images. When you select an image, the image pixel data is scanned using client-side WebAssembly to locate finder patterns. The tool can read QR Code, EAN-13, EAN-8, UPC-A, Code 128, Code 39, ITF, and more. Processing happens instantly in your browser — your images are never uploaded to any server.
