About Barcode Scanner

The 'Barcode Scanner' is a powerful online tool that automatically detects and decodes barcodes and QR codes from uploaded image files (JPG, PNG, WebP, etc.) directly in your browser. Simply drag and drop an image containing a barcode or QR code, and the tool will instantly identify the encoded data — whether it is a product number, URL, text message, or any other information.

Supported barcode formats include EAN-13 (international standard for retail products), EAN-8 (compact version for small packages), UPC-A (widely used in North America), Code 128 and Code 39 (commonly used in logistics and shipping), QR Code (ubiquitous in mobile payments and marketing), and DataMatrix (used in manufacturing and pharmaceutical industries).

Use it to extract product numbers from photographs, inspect QR codes on documents, or check an encoded URL before opening it.

Processing runs in your browser. A local decoder also works when the browser's native detection API is unavailable; this decoder returns one code per scan, so crop multiple codes into separate images. Check digits are validated for EAN-13, EAN-8, and UPC-A, but this does not guarantee that the result matches the original information.

How to use Barcode Scanner

Drag and drop an image file (JPG, PNG, WebP, etc.) containing barcodes or QR codes into the central drop area.
Press Scan to read the code. For multiple codes, crop and scan each one separately.
Review the results (format type, decoded value, validation status) and use the copy button to copy values to your clipboard as needed.
