Barcode Scanner

Scan QR codes and barcodes with your webcam or a photo, decoded locally by the browser's own engine.

Symbologies to look for

QR code EAN-13 EAN-8 UPC-A Code 128 Code 39 Data Matrix PDF417

Tick fewer boxes to make detection faster and pickier. Formats your browser cannot decode are greyed out automatically.

Live camera scan

Hold a symbol steady inside the frame. The same code is not re-added to the list while it stays in view; look away or scan something else and it registers again.

Or decode a saved photo

Nothing leaves your device: the camera feed is never sent anywhere, frames are decoded in-page by the browser, and the scan list lives only in this tab.

What Is Barcode Scanner?

The Barcode Scanner reads codes straight from your webcam or a saved photo using the native BarcodeDetector API built into the browser itself. You choose which symbologies to hunt for, from QR codes and EAN or UPC retail bars to Code 128, Code 39, Data Matrix and PDF417, and a repeating guard keeps the same symbol from flooding the list while it stays in view. Each hit shows its type and value with copy and safe link buttons, and unsupported browsers get an honest notice naming the engines that do work.

Who Uses the Barcode Scanner?

Shoppers checking product codes, warehouse staff and developers testing generated barcodes use it to decode locally without installing an app.

How to Use the Barcode Scanner

Tick the symbologies you want in the format panel; undecodable ones are greyed out.
Press Start camera and hold a code in frame, or drop a photo onto the pad to scan it once.
Copy the value, open it when it is a safe http link, or revisit anything in the session list.

Why Choose Our Barcode Scanner?

Uses only the native API; no decoder library is loaded
Camera loop with anti-repeat keeps the list clean
Link button appears only for valid http or https payloads
