Barcode Generator

Generate various types of barcodes including Code 128, EAN, UPC, Code 39, and more. Customize appearance and download as PNG, SVG, or PDF. All processing is done in your browser for privacy.

Overview

This barcode generator runs entirely in your browser, so the values you encode — product SKUs, serial numbers, inventory codes — never leave your device. Choose from ten industry-standard formats including Code 128, EAN-13, UPC-A, Code 39, ITF, MSI, Pharmacode, and Codabar, then download each barcode as a lossless SVG, a print-ready PDF, or a raster PNG. Need dozens at once? Upload a CSV and the tool renders the full batch client-side, letting you export everything as individual files or a single combined PDF — all without a server, an account, or a subscription.

Key Features

  • Generate multiple barcode formats (Code 128, EAN, UPC, Code 39, ITF, MSI, Pharmacode, Codabar)
  • Bulk generation from CSV files
  • Customizable appearance (colors, size, text display)
  • Download as PNG, SVG, or PDF
  • Bulk export to separate files or single PDF
  • Real-time preview as you type
  • Responsive design with visual background

Common Use Cases

  • Retail Product Labeling — Small shop owners generate EAN-13 or UPC-A barcodes for product packaging without paying for barcode software or exposing their SKU list to a third-party server.
  • Warehouse & Inventory Management — Operations teams bulk-generate Code 128 or ITF barcodes from a CSV export of their inventory spreadsheet and print the entire batch as a single PDF.
  • Library & Asset Tracking — Libraries and IT departments create Codabar or Code 39 barcodes for books, equipment, or asset tags and download scalable SVGs that print sharply at any size.
  • Healthcare & Pharmacy — Pharmacode barcodes required on pharmaceutical packaging can be previewed and exported instantly without uploading sensitive product data to an external service.
  • Prototyping & QA Testing — Developers and QA engineers generate sample barcodes of specific formats to test scanner hardware or barcode-reading code without needing a dedicated label printer application.

How It Works

Frequently Asked Questions

What barcode formats are supported?
We support Code 128, EAN-13, EAN-8, UPC-A, UPC-E, Code 39, ITF (Interleaved 2 of 5), MSI, Pharmacode, and Codabar formats for various industry applications.

Can I generate multiple barcodes at once?
Yes, you can upload a CSV file with multiple values to generate barcodes in bulk. You can then download them as individual files or combine them into a single PDF.

What's the difference between Code 128 and Code 39?
Code 128 is more compact and can encode all ASCII characters, making it ideal for general use. Code 39 is older, larger, but widely supported and can only encode uppercase letters, numbers, and some symbols.

Are there character limits for barcode content?
Yes, limits vary by format. Code 128 can handle very long strings, while UPC codes require exactly 12 digits. The tool will validate your input and show any format requirements.

Can I customize the appearance of barcodes?
Yes, you can change colors, adjust size, and control whether text is displayed below the barcode. You can also set margins and other formatting options.

What file formats can I download barcodes in?
You can download barcodes as PNG (for web use), SVG (scalable vector), or PDF (for printing). Bulk exports can be saved as individual files or combined into one PDF.

Is my barcode data stored on your servers?
No, all barcode generation happens locally in your browser. Your data never leaves your device, ensuring complete privacy and security.
