常見問題
- Does my image leave my device?
- No. Decoding uses the browser BarcodeDetector API entirely on-device.
- Which formats are supported?
- QR codes, EAN-13, UPC, Code 128, PDF417, Data Matrix, and more — anything your browser BarcodeDetector implements.
- What if my browser does not support BarcodeDetector?
- Some browsers (Firefox, Safari) do not yet ship BarcodeDetector. We show a clear message and link to alternatives.
