Free QR Code Reader & Scanner – Live Camera & Image File Upload

The Free QR Code Reader & Scanner provides high-speed 2D matrix barcode decoding through your browser using hardware-accelerated computer vision algorithms. Supporting both real-time webcam video stream scanning and static file uploads (PNG, JPG, WEBP, GIF, SVG), the scanner decodes Quick Response matrices to extract embedded text payloads, website URLs, Wi-Fi network configurations, vCard contact information, cryptocurrency wallet addresses, and multi-factor authentication TOTP setup secrets. This utility is invaluable when you receive a digital flyer or meeting invite containing a QR code on your laptop screen and cannot easily scan it with your smartphone, or when you need to inspect an unknown QR code safely without automatically opening a malicious URL in a mobile browser. The decoder runs strictly in client memory, meaning no scanned URLs or credentials leave your computer. One physical constraint to consider is that heavily damaged, smudged, or low-resolution camera feeds where alignment position patterns (the three square finder corners) are occluded will fail mathematical Reed-Solomon error correction and cannot be recovered.
