FAQ — How does this tool work?
What does this tool do?
This reader decodes QR and barcode payloads locally in your browser and displays the raw content — nothing is automatically opened.
Does any data leave my device?
No. All processing happens locally. No images or decoded data are sent to our servers.
Can I use it offline?
Yes — after the page has loaded, the scanner will work without an internet connection as long as the library is available.
What formats are supported?
The tool recognizes QR codes and many common barcode formats. If a code isn't detected, try better lighting, a different angle, or another camera.
Troubleshooting / Permissions
If the camera doesn't start, check browser permissions or try a different camera source. The exact error message will be shown below the reader to help with diagnostics.
