What is a Barcode Generator?

A Barcode Generator is a free online tool that creates industry-standard barcodes from your text or numerical data. It supports multiple barcode formats including Code 128, Code 39, EAN-13, EAN-8, UPC-A, ITF, and more. Generate barcodes for product labels, inventory management, shipping labels, event tickets, library books, and any system that uses barcode scanning for data capture.

Why use barcodes?

Barcodes enable instant, error-free data capture. Manually typing product codes, inventory numbers, or tracking IDs is slow and prone to typos. Barcode scanners read data in milliseconds with near-perfect accuracy. From retail checkout to warehouse management, hospital patient tracking to library systems, barcodes streamline operations and eliminate human data entry errors.

Barcode format guide

Code 128: Most versatile, supports all ASCII characters, used for shipping and logistics. EAN-13: 13-digit standard used for retail products worldwide. UPC-A: 12-digit standard used primarily in North America. Code 39: Alphanumeric, commonly used in manufacturing and military. EAN-8: Compact 8-digit version for small product packaging. Choose the format that matches your industry standard and scanning equipment.

How to generate a barcode?

Enter your data (text or numbers depending on format), select the barcode type, customize the size and display options (show/hide text below the bars), and generate your barcode. Download it as a PNG or SVG image and use it in your labels, documents, or applications. The tool validates your input to ensure it meets the requirements of your chosen format.
