Barcode Generator is a versatile tool for creating professional-quality barcodes in over 17 different formats including EAN-13, UPC-A, Code 128, DataMatrix, PDF417, and Aztec codes. It offers extensive customization with color presets, decorative frames, captions, rotation, and sizing controls. The tool also supports batch generation of up to 100 barcodes via CSV import, barcode scanning from camera or uploaded images, and export in PNG or PDF format. Everything runs directly in your browser with no software installation required.
Select barcode type
Select the barcode type that suits your intended use. Please select Code128 for general logistics and EAN-13 or UPC-A for product code.
Enter Data
Enter the data to be encoded in the barcode. Depending on the barcode type, only numbers can be entered or there may be a limit to the number of digits.

It depends on the intended use. We recommend EAN-13 (International) or UPC-A (North America) for general merchandise, Code128 for logistics/inventory management, and Code39 for industrial use. DataMatrix, a 2D barcode, is suitable for small parts or medical devices.
Yes, check digits are automatically calculated for retail barcodes such as EAN-13 or UPC-A. When you enter 12 digits (EAN-13) or 11 digits (UPC-A), the last check digit is automatically added.
Yes, since it is created to standard specifications, it can be scanned normally with a regular barcode scanner. However, please be careful as the recognition rate may decrease if you print in too small a size or if the contrast between the bar color and background color is weak.
You can create up to 100 barcodes at once by uploading the CSV file in the Batch tab or by entering the data directly. Generated barcodes can be downloaded in bulk as a ZIP file or exported to CSV.
As long as there is sufficient contrast between the bar color and the background color, changing the color will not cause any problems in scanning. A combination of a dark bar color and a light background color is generally recommended; red-based bar colors may be difficult to recognize on some red laser scanners.
