Free Barcode Generator: Create EAN-13, UPC-A, ITF-14 & GS1-128 Barcodes

Whether you need a barcode for your product packaging, a retail shelf label, or a shipping carton, generating the right barcode format from your GTIN is essential. Our free barcode generator creates print-ready EAN-13, UPC-A, ITF-14, and GS1-128 barcodes that you can download as SVG (vector) or PNG (raster) files. This guide explains each barcode type, when to use it, and how to generate barcodes that meet industry specifications.

Types of Barcodes: Which Format Do You Need?

Different barcode formats serve different purposes. Here is a comparison to help you choose the right one:

When to Use Each Barcode Format

EAN-13: The Global Standard

EAN-13 is the most widely used retail barcode format in the world. If you sell products internationally, in India, Europe, Asia, or anywhere outside North America, EAN-13 is your go-to format. It encodes a 13-digit GTIN and is scanned at every major retail chain worldwide.

UPC-A: North American Retail

UPC-A is the 12-digit barcode format used primarily in the United States and Canada. If you are selling on Amazon.com or in US retail stores, you will need UPC-A barcodes. Note: a UPC-A barcode is essentially an EAN-13 with a leading zero. Use our GTIN Converter to switch between formats.

ITF-14: Shipping and Wholesale

ITF-14 barcodes are used on outer shipping cartons and cases. They encode a 14-digit GTIN that includes an indicator digit (1-8) before the standard GTIN, identifying the packaging level. ITF-14 barcodes are designed to be printed directly on corrugated cardboard without requiring labels.

GS1-128: Logistics Data Carrier

GS1-128 (formerly UCC/EAN-128) is the most versatile barcode format. It can encode multiple data fields using GS1 Application Identifiers: GTIN, batch number, expiry date, serial number, weight, and more. It is required for shipping labels in most major supply chains.

How to Generate Barcodes

SVG vs PNG: Which Download Format?

Recommendation: Use SVG for anything going to print (product packaging, labels). Use PNG for digital use (online listings, documents). SVG files can be opened in Adobe Illustrator, Inkscape, or any vector graphics editor.

Barcode Sizing and Placement Guidelines

For barcodes to scan reliably at retail, follow these GS1 sizing guidelines:

• EAN-13 nominal size: 37.29mm wide x 25.93mm tall (100% magnification)
• Magnification range: 80% to 200% of nominal size
• Quiet zones: Leave at least 3.63mm clear space on each side of the barcode
• Contrast: Dark bars on a light background. Black on white is ideal
• Placement: Bottom right of the back panel is the standard position for retail products

Frequently Asked Questions

Can I generate barcodes without a GS1 membership?

Our tool generates barcode images from any valid GTIN you provide. However, to have a legitimate barcode that is recognized by retailers, you need a GTIN assigned through GS1. The generator creates the visual barcode; GS1 membership provides the number behind it.

What resolution do I need for print?

For print, download the SVG format. SVG is resolution-independent, so it will be crisp at any print size. If you must use PNG, ensure it is at least 300 DPI at the final print size.

Is the barcode generator free?

Yes, completely free. Generate unlimited barcodes in EAN-13, UPC-A, ITF-14, and GS1-128 formats. No account required.
