What Is an Online Barcode Scanner?
An online barcode scanner uses your device's camera — webcam on desktop, rear camera on mobile — to decode barcodes and QR codes entirely in the browser. Unlike dedicated barcode scanner hardware, it requires no drivers, no installation, and no special equipment. It is useful for quick stock lookups, verifying barcode labels, checking in received goods, or simply decoding a QR code you encounter. This scanner supports over 10 barcode formats including all major retail (EAN, UPC), logistics (Code128, ITF), and 2D (QR Code, Data Matrix, PDF417) formats.
How to Scan a Barcode Online in 2 Steps
Step 1 — Click Start Scanner & Allow Camera
Click the Start Scanner button. Your browser will ask for camera permission — click Allow. On mobile, the rear camera is used by default for better barcode scanning. On desktop, your webcam activates.
Step 2 — Point at the Barcode
Hold the barcode or QR code in front of the camera inside the targeting frame. The scanner decodes it instantly and shows the result in the panel on the right. Scan history is kept for your session. Click Copy to copy any result to the clipboard.

Frequently Asked Questions
What barcode formats does this scanner support?
The scanner supports QR Code, Code128, Code39, Code93, EAN-13, EAN-8, UPC-A, UPC-E, ITF (Interleaved 2 of 5), PDF417, Data Matrix, and Aztec. These cover virtually all barcodes used in retail, logistics, and inventory management.
Does it send my camera feed to any server?
No. All scanning happens entirely in your browser using JavaScript. Your camera feed is never uploaded to any server. No data is stored or transmitted.
Why is the scanner not working?
The most common cause is camera permission being denied. Click the camera icon in your browser's address bar and set permission to Allow, then refresh the page. Also ensure you are using HTTPS (this page uses HTTPS), as camera access requires a secure connection.
Can I scan barcodes on my phone?
Yes. Open this page in your phone's browser (Chrome on Android, Safari on iOS) and click Start Scanner. The rear camera activates for better scanning. Most phone cameras work well for all barcode types.
Can I scan from an image file instead of a camera?
The current version scans using a live camera feed. For scanning from a static image, use your phone's built-in camera app (which can scan most QR codes natively) or take a photo and open it in Google Lens.
Is this barcode scanner free?
Yes, fully free. No account, no download, no subscription required.
