Barcode Generator

How to Use the Barcode Generator

1. Select Format: Choose your barcode standard from the dropdown — CODE128 (universal), EAN-13 (retail products), UPC-A (North America), CODE39 (logistics), ITF-14 (shipping), MSI (inventory), or Pharmacode (pharmaceutical).
2. Enter Value: Type or paste the data to encode. Each format has specific requirements — EAN-13 needs exactly 13 digits, UPC needs 12, CODE128 accepts any text.
3. Customize Appearance: Adjust bar width and height using sliders, choose foreground and background colors with the color pickers, and toggle the text display checkbox.
4. Generate & Export: Click "Generate Barcode" to render the barcode. Then download as "Download PNG" for print or "Download SVG" for vector scalability, or "Copy Image" to paste directly into documents.

Technical Overview & Use Cases

This barcode generator uses the JsBarcode library to render industry-standard 1D barcodes on HTML5 Canvas. It supports 8 barcode symbologies, each conforming to their respective ISO/GS1 standards. CODE128 uses variable-length encoding with three character sets (A, B, C) for maximum density. EAN/UPC barcodes include built-in check digit validation — the generator calculates and verifies Modulo-10 checksums automatically. SVG export produces resolution-independent vectors suitable for professional print at any DPI.

Real-world use cases:

• Product labeling: Generate EAN-13 or UPC barcodes for retail products, inventory items, or internal asset tracking systems.
• Shipping & logistics: Create ITF-14 barcodes for shipping containers and cartons conforming to GS1 supply chain standards.
• Library & archive systems: Generate CODE39 barcodes for book cataloging, document tracking, or membership cards.

Privacy & Security Guarantee

This tool is part of the FAK LAB ecosystem, founded by Faizan Ahmad Khan Khichi. Barcode generation happens 100% in your browser using client-side Canvas rendering. The data you encode is never sent to any server — the barcode is computed and drawn locally. No product codes, serial numbers, or business data leaves your device. Export files are created in-memory and downloaded directly.

Frequently Asked Questions

Which barcode format should I choose?

For general use, CODE128 is the most versatile — it encodes any ASCII character efficiently. For retail products sold in stores, use EAN-13 (international) or UPC-A (North America). For shipping containers, use ITF-14. For simple alphanumeric labels, CODE39 is widely compatible with older scanners.

Can I scan these barcodes with a standard scanner?

Yes. All barcodes generated by this tool conform to their respective ISO/GS1 standards and are readable by any compliant barcode scanner — handheld laser scanners, camera-based readers, and smartphone apps. The PNG output is print-ready at standard label sizes.

What is the difference between PNG and SVG export?

PNG is a raster image — it has fixed resolution and may pixelate if enlarged beyond its original size. SVG is a vector format — it scales infinitely without quality loss, making it ideal for professional printing, large signage, or dynamic resizing in web applications. Use SVG for print and PNG for quick digital sharing.
