Barcode Generator

Generate professional barcodes in multiple formats. Perfect for product labels, inventory management, retail, and shipping.

Why use a barcode generator

Barcodes are essential for retail, inventory, shipping, and product management. Unlike QR codes which are designed for consumer interaction (like scanning a menu), barcodes are optimized for quick scanning at point-of-sale, inventory tracking, and logistics. They encode data in a linear format that scanners can read quickly and reliably.

This tool generates static barcodes directly in your browser. No data is ever sent to a server — everything runs locally.

How it works

1. Enter the data you want to encode
2. Select the barcode format (CODE128, EAN-13, UPC-A, etc.)
3. Adjust the height
4. Generate and preview the barcode
5. Download as PNG or SVG

Supported formats

| Format | Use Case | Example |

|--------|----------|---------|

| CODE128 | General purpose (alphanumeric) | ABC123 |

| CODE39 | General purpose (alphanumeric) | ABC123 |

| EAN-13 | Retail products (13 digits) | 1234567890123 |

| EAN-8 | Small products (8 digits) | 12345678 |

| UPC-A | North American retail (12 digits) | 123456789012 |

| ITF-14 | Shipping cartons (14 digits) | 12345678901234 |

| MSI | Inventory management | 123456 |

| Pharmacode | Pharmaceutical tracking | 123456 |

| Codabar | Libraries, blood banks | A123B |

Format-specific requirements

• EAN-13: Exactly 13 digits
• EAN-8: Exactly 8 digits
• UPC-A: Exactly 12 digits
• ITF-14: Exactly 14 digits

Tips for creating perfect barcodes

1. Use the right format — Choose the format that matches your industry standard.
2. Keep data concise — Shorter barcodes are easier to scan.
3. Use appropriate height — Taller barcodes are easier to scan, especially in retail.
4. Avoid scaling barcodes — Always generate at the correct size rather than resizing.
5. Test before printing — Always test with a real scanner before mass printing.
6. High contrast — Black bars on white background scan best.

Batch generation

Generate multiple barcodes at once by entering one per line. This is useful for:

• Creating product labels
• Generating inventory stickers
• Bulk shipping labels
• Event badge barcodes

Export options

• PNG — High-quality raster image for print and web
• SVG — Vector format for scaling without quality loss
• ZIP — Download multiple barcodes as a compressed archive

Privacy and security

All processing happens locally in your browser. Your data never leaves your device. No internet connection is required after the page loads.
