OnBarcode.com Free QR Code Scanner — Fast, Secure, and Easy to Use

How to Use OnBarcode.com Free QR Code Scanner: A Quick Guide

1) Download & install

• Go to https://www.onbarcode.com/scanner/ and download the “QR Code Scanner” (Windows).
• Run the installer or extract the portable executable.

2) Launch the app

• Open BarcodeLabelsScanner.exe (or the QR Code Scanner executable).

3) Choose barcode type

• Select QR Code from the barcode-type list (recommended for best accuracy).

4) Load an image or capture

• Click Load Barcode Image and select a JPG/PNG/GIF/BMP/TIFF file, or drag-and-drop the image into the app.
• If the app supports webcam capture, use the camera option to point at a printed/displayed QR code.

5) Scan & read

• Click the Scan or OK button. The scanner will decode the QR code and display the extracted data in the result textbox.

6) Troubleshooting tips

• If no result: try cropping the image to contain only the QR area, increase contrast, rotate image to correct orientation, or use a higher-resolution image.
• Multiple QR codes: scan one code at a time for higher reliability.
• Unsupported image: convert multi-page TIFFs to single-page or export as PNG/JPEG.

7) Integration (for developers)

• Use OnBarcode .NET/Java SDKs if you need programmatic scanning: install the appropriate package (e.g., OnBarcode.Barcode.Reader via NuGet) and call BarcodeScanner.Scan(“file”, BarcodeType.QRCode) to get decoded strings.

8) License & support

• The scanner is offered free for personal/business use on OnBarcode’s site; check their download page for licensing details and support links.
