About Barcode Generator
Barcode Generator is a powerful tool that creates industry-standard linear barcodes (1D barcodes) directly in your browser. Unlike QR codes which are two-dimensional, linear barcodes encode data in the varying widths and spacing of parallel lines. These traditional barcodes are used on retail products, inventory tracking, shipping labels, asset tags, library books, and more. Our generator supports 10 barcode formats: CODE128 (alphanumeric, most versatile), CODE39 (alphanumeric, widely used in manufacturing), EAN-13 (13-digit retail standard), UPC (12-digit North American retail), EAN-8 (compact retail), EAN-5 and EAN-2 (supplemental add-ons), ITF-14 (shipping containers), MSI (numeric inventory), and Pharmacode (pharmaceuticals). Each barcode format has specific validation rules to ensure the data can be properly encoded—for example, EAN-13 and UPC require exact digit counts with valid check digits. Real-time validation provides helpful error messages explaining the requirements for each format. Customize bar width (1-4), bar height (50-200px), foreground and background colors, text display, and font size to match your branding and requirements. Larger bar heights are better for scanning, and good contrast between bars and background ensures reliable readability. Download as PNG for printing at 2x resolution for crisp output, or SVG for vector graphics that scale infinitely without quality loss. All barcode generation happens entirely in your browser using the JsBarcode library—your data is never sent to servers. Perfect for product labeling for retail items (EAN-13, UPC), inventory tracking with CODE128 for warehouse labels, shipping labels with ITF-14 for carton identification, asset tags for equipment tracking, library books with CODE39 or CODE128, membership cards and ID badges, numbered tickets with CODE39 or CODE128, receipts and invoices with barcode tracking, event tickets with barcode entry verification, packaging barcodes for manufactured goods, and serial number labels. Use this tool to generate professional, scannable barcodes that work with all standard barcode scanners—no account required, completely free.
