What Is This Tool?

The HandleKit Barcode Studio is a free, browser-based generator that lets you create scannable 1D barcodes in seconds. It supports the most widely used industry formats—Code 128, Code 39, EAN-13, and UPC-A—for shipping, retail, and inventory management.

Everything runs entirely in your browser. Your data is never sent to a server, and the resulting image is yours to download and use freely—no watermarks, no sign-up, no limits.

Which Format Should I Use?

Use Code 128 for general-purpose alphanumeric data like shipping labels and warehouse tracking. Choose EAN-13 or UPC-A for retail products. If you need a website link or more data in a square format, use our dedicated QR Generator Tool.

Tips for Reliable Scanning

Always use high contrast between the barcode and background—dark bars on a light surface work best. Make sure the barcode has enough quiet zone (blank space around it), and test the output with a real scanner before printing at scale.

Supported Barcode Formats

Code 128: The most versatile 1D barcode. Supports full ASCII, compact encoding, and is ideal for logistics, shipping, and internal tracking.
Code 39: A widely supported legacy format used in automotive, defense, and healthcare industries. Encodes uppercase letters, digits, and a few special characters.
EAN-13: The global retail standard for product identification. Requires exactly 13 numeric digits (including check digit).
UPC-A: The North American retail standard. Requires exactly 12 numeric digits. Used on virtually all consumer products sold in the US and Canada.

Why does my EAN-13 or UPC barcode show an error?
