Why Barcodes Matter

Barcodes are everywhere — from retail products and shipping labels to inventory management and library books. They provide a fast, reliable way to encode and retrieve data using optical scanners. Different industries use different barcode formats: retail uses EAN and UPC, logistics uses ITF-14 and CODE128, and libraries often use CODE39.

This generator creates barcodes entirely in your browser — no data is ever sent to any server. You can customize colors and size, and download your barcode as a PNG image for use in product labels, packaging, or digital documents.
