Barcode scanner

Decode barcodes from an image — Code 128, EAN-13, EAN-8, ITF, Data Matrix and more. Uses the browser's native BarcodeDetector API.

Your browser does not support the BarcodeDetector API. Try Chrome or Edge.

Features

Decodes EAN-13, EAN-8, UPC-A, UPC-E, Code 128, Code 39, Code 93, Codabar, ITF, Data Matrix, Aztec, PDF417 and QR codes.
Reads from a still image — handy for checking a label photo or a screenshot of a code.
Runs on the browser's built-in BarcodeDetector API, so the picture is decoded on your device and never uploaded.

How it works

Drop a barcode image or click to select a PNG, JPG or WebP from your device.
The native BarcodeDetector reads it instantly — the format and decoded value appear.
Copy the decoded value to use it in your inventory, catalog or shipping workflow.

Your files never leave this page

Every conversion runs entirely in your browser using WebAssembly. There is no upload, no server-side processing, no analytics, and no cookies. Open DevTools → Network during the operation and you will see zero outbound traffic.
