What is the Barcode Generator?
The WorldOfTools Barcode Generator is a free, instant, browser-based tool that creates professional barcodes in 6+ industry-standard formats — including EAN-13, UPC-A, Code-128, Code-39, ITF-14 and MSI. Whether you're generating barcodes for retail products, inventory management, shipping labels, Amazon FBA, or Flipkart listings, this tool produces print-ready SVG and PNG output with zero watermark.
Unlike other online barcode tools, all generation happens entirely in your browser using the open-source JsBarcode library. Your barcode data is never sent to any server, never stored, and never tracked — making it suitable for confidential product SKUs, internal codes, and business inventory.
How to Generate a Barcode — Step by Step

Enter Your Data — Type the number or text to encode. The barcode updates in real-time as you type. Check the format hint for input rules.
Customize (Optional) — Adjust bar width, height, and colors to match your label or packaging design requirements.
Download — Click Download SVG for print-quality scalable output, or Download PNG for a raster image file. SVG is recommended for professional printing.

Frequently Asked Questions
What barcode format should I use for retail products in India?
Use EAN-13 for retail products — it's the international standard used in India and globally, readable by all POS scanners. You'll need a GS1 company prefix for official use. For internal inventory without GS1 registration, Code-128 is the most flexible choice.
What's the difference between EAN-13 and UPC-A?
EAN-13 uses 13 digits and is the international standard (used in India, Europe, Asia). UPC-A uses 12 digits and is the standard in the US and Canada. Both are read by the same scanners — EAN-13 actually includes UPC-A as a subset.
Can I use this for Amazon FBA or Flipkart barcodes?
Yes. Code-128 and EAN-13 are both supported. Download as SVG for high-quality print output at any size. Always verify your platform's exact barcode format requirements (Amazon typically uses UPC/EAN, Flipkart uses EAN-13).
Why use SVG instead of PNG for downloading?
SVG (Scalable Vector Graphics) can be scaled to any size without losing sharpness — essential for label printing and packaging. PNG is a raster image that can appear blurry if enlarged. Use SVG for professional print use, PNG for web or screen display.
Is this barcode generator completely free with no watermark?
Yes — 100% free, no watermark, no account required. All barcodes are generated using the open-source JsBarcode library entirely in your browser. Your data never reaches any server.
What's the maximum data length for Code-128?
Code-128 can technically encode up to 48 characters (though the practical limit for scannable barcodes is around 30-40 characters). For longer data, use a QR code instead.
