What Is a QR Code Reader?
A QR code reader scans an image containing a QR code and extracts the text or link it encodes. This tool uses your browser's own native barcode-detection capability (the BarcodeDetector API, available in Chromium-based browsers like Chrome and Edge) to read the code directly from an uploaded image.
Because it relies on a built-in browser feature rather than a third-party scanning library or a server upload, the image you choose is processed locally and is never sent anywhere — though it does mean the tool only works in browsers that support this API.
