Free Online Barcode Scanner — Decode Barcodes Instantly
Our free online barcode scanner lets you read and decode barcodes directly in your web browser. Whether you need to scan a product barcode from a photo, read a shipping label, or decode a Code 128 barcode from a screenshot, this tool handles it all without any software installation. Simply upload an image containing a barcode or use your device's camera to scan barcodes in real time.
This barcode scanner tool leverages the modern BarcodeDetector API built into Chromium-based browsers like Google Chrome and Microsoft Edge. This means barcode detection happens locally on your device — your images are never uploaded to any server, ensuring complete privacy and lightning-fast performance. The tool supports a wide range of barcode formats including EAN-13, EAN-8, UPC-A, UPC-E, Code 128, Code 39, Code 93, ITF, Codabar, Data Matrix, and QR codes.
How to Use the Barcode Scanner
Using our barcode scanner is straightforward. You have two options for scanning barcodes:
- Upload an Image: Click the upload area or drag and drop an image file containing a barcode. The tool will automatically detect and decode any barcodes found in the image. Supported formats include JPG, PNG, GIF, BMP, and WebP.
- Camera Scan: Switch to the Camera Scan tab and click "Start Camera" to activate your device's camera. Point the camera at a barcode and the tool will continuously scan the video feed for barcodes in real time. This is ideal for scanning physical products, labels, or documents.
Once a barcode is detected, the decoded value appears below the scanner along with the barcode format. You can copy the decoded value to your clipboard with a single click using the Copy button.
Supported Barcode Formats
This scanner supports all major 1D and 2D barcode symbologies recognized by the BarcodeDetector API:
- 1D Barcodes: EAN-13, EAN-8, UPC-A, UPC-E, Code 128, Code 39, Code 93, ITF (Interleaved 2 of 5), Codabar
- 2D Barcodes: QR Code, Data Matrix, Aztec, PDF417
These barcode types cover the vast majority of use cases — from retail product barcodes (EAN/UPC) to logistics and inventory management (Code 128, ITF) to modern 2D codes used in mobile payments and digital tickets (QR Code, Data Matrix).
Why Use an Online Barcode Scanner?
An online barcode scanner offers several advantages over dedicated hardware scanners or mobile apps. It requires no installation and works on any device with a modern browser. It's ideal for occasional barcode scanning tasks such as checking product information, verifying shipping labels, reading barcodes from screenshots or documents, and inventorying items. Since all processing happens in the browser, your data stays private and the results are instant.
For developers and businesses, browser-based barcode scanning can be integrated into web applications for inventory management, point-of-sale systems, asset tracking, and warehouse management. The BarcodeDetector API provides a native, high-performance solution without requiring third-party libraries or server-side processing.
