Barcode Generator
Free Online Tool

Barcodes are the invisible infrastructure powering modern commerce, inventory management, shipping logistics, and asset tracking worldwide. However, developers and businesses often struggle to find a reliable, free barcode generator that supports multiple industry-standard formats, offers real-time validation, provides high-quality output in multiple file formats, and respects user privacy by generating barcodes entirely client-side. Most online barcode generators support only one or two basic formats like CODE128, leaving users without access to specialized formats like EAN-13 for retail products, ITF-14 for shipping containers, MSI for inventory systems, or Pharmacode for pharmaceutical packaging. This comprehensive barcode generator tool was created to provide developers, small businesses, designers, and logistics professionals with a free, feature-rich barcode creation solution that supports 10 industry-standard formats, generates print-ready and web-optimized output, validates input in real-time, and operates 100% offline in your browser without sending any data to servers.

Our barcode maker addresses critical pain points in the barcode generation workflow. Whether you are a developer building an inventory management system that needs CODE39 barcodes, an e-commerce business creating EAN-13 or UPC-A product barcodes for retail, a logistics company generating ITF-14 shipping container codes, a warehouse manager creating CODE128 asset tracking labels, or a pharmaceutical company producing Pharmacode labels for medication packaging, this tool provides the format-specific validation and customization you need. Real-time validation prevents costly errors by alerting you immediately if your input doesn't match the selected format's requirements - no more discovering invalid barcodes after printing thousands of labels. Customization options let you adjust bar width for different printer resolutions, set height for label sizes, choose colors for branding requirements, and fine-tune margins for precise label positioning. Export options include SVG for infinite scalability and professional printing, PNG and JPEG for standard printing and digital use, and WEBP for modern web applications requiring smaller file sizes.

Beyond basic barcode generation, this tool educates users on format selection with detailed descriptions of each barcode type, use cases, character support, and example values. Knowing when to use CODE128 versus CODE39, or understanding why EAN-13 requires exactly 13 digits while CODE128 supports alphanumeric text, empowers users to make informed decisions that prevent integration issues and scanning failures. The live preview lets you verify barcode appearance before download, while the instant download feature streamlines bulk barcode creation workflows. RJL.io is committed to building free developer tools that combine professional-grade functionality with privacy-first design - and this barcode generator exemplifies that mission by delivering enterprise-quality barcode creation without data collection, subscriptions, or artificial limitations.
