About This Tool
Barcode Generator is a standards-compliant, in-browser barcode creation utility engineered for retail merchants, warehouse managers, eCommerce fulfillment teams, and product packaging designers. Barcodes are the fundamental backbone of modern inventory management, point-of-sale (POS) checkout scanning, logistics tracking, and library indexing.
Our generator supports the industry's most widely utilized linear 1D barcode symobologies: - Code 128: Universal high-density alphanumeric barcode utilized worldwide in packaging, shipping labels, and logistics. - EAN-13: International 13-digit standard for retail products, books (ISBN), and supermarket goods outside North America. - UPC-A: The standard 12-digit barcode used across all retail merchandise and consumer goods in the United States and Canada. - Code 39: Alphanumeric barcode widely mandated across military, automotive, and healthcare applications.
Export your generated barcode as a crisp, high-resolution PNG for web listings or as an infinitely scalable vector SVG for print packaging, product labels, and Adobe Illustrator / InDesign vector layouts.

Frequently Asked Questions
What is the difference between Code 128 and UPC barcodes?
UPC-A is strictly a 12-digit numeric barcode used at retail point-of-sale in North America. Code 128 is an alphanumeric standard that can encode letters, numbers, and symbols, making it the preferred choice for internal inventory, shipping labels, and serial numbers.
Can I print these barcodes on commercial thermal label printers?
Yes. Downloading the vector SVG or high-resolution PNG produces crisp lines that print with laser precision on Zebra, Brother, Dymo, and standard laser printers.
Does this generator assign official GS1 company prefixes?
No. This tool generates standard visual barcode symbols from your input numbers. To obtain official globally unique retail barcodes registered with GS1, you must license a GS1 company prefix from gs1.org.
Are any watermarks added to the barcodes?
No. All generated barcodes are 100% clean and ready for commercial use.
Is this barcode generator free?
Yes, 100% free with unlimited generation and zero restrictions.
