About this tool
Read QR codes from camera or image with BarcodeDetector. Free, client-side. QR Code Reader runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- QR Code Reader is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
