The barcode reader supports EAN-13, EAN-8, UPC-A, UPC-E, Code 128, Code 39, QR Code, and ITF (Interleaved 2 of 5). These cover the most common barcode types found on retail products, shipping labels, and marketing materials.

Why does it say my browser is not supported?

This tool uses the BarcodeDetector API, which is currently available in Google Chrome 83+, Microsoft Edge 83+, and Opera 69+ on desktop and Android. Safari and Firefox do not yet support this API. Open the page in a supported browser to use the scanner.

Is my image uploaded to a server?

No. All barcode detection runs entirely in your browser using the built-in BarcodeDetector API. No images or data leave your device. The tool works offline once the page is loaded.

Can I scan multiple barcodes from one image?

Yes. If your image contains multiple barcodes, the tool will detect and display all of them. Each detected barcode is shown with its format type and decoded value, and you can copy each one individually.

What image formats are accepted?

You can upload PNG, JPEG, GIF, WebP, BMP, and SVG images. For best results, use a clear photo where the barcode is fully visible and not blurred. Higher resolution images generally produce better scanning accuracy.
