Barcode Scanning in the Browser: How It Works

You do not need a dedicated app to read a barcode. A browser scanner uses your camera or an uploaded image to decode it instantly.

1D and 2D

It reads linear codes like EAN, UPC and Code 128, plus 2D codes like QR and Data Matrix.

Private by design

Decoding happens on your device, so the image never leaves your browser.

Tips for a clean read

Hold steady, fill the frame with the code, and avoid glare. For damaged labels, try the image-upload mode and a sharper photo.
