Barcode Generator Online Free — Code 128, EAN-13, UPC-A & Code 39

Create standard retail, logistics, and inventory barcodes in SVG and PNG formats.. Generate Code 128, EAN-13, UPC-A, Code 39, and ITF barcodes with adjustable dimensions, line colors, and vector SVG / PNG export.

What is Barcode Maker and what does it do?

The Barcode Generator & Exporter is a client-side barcode creation utility that generates industry-standard 1D barcodes including Code 128, EAN-13, UPC-A, Code 39, and ITF-14 with customizable sizing and vector SVG / PNG export.

Powered by the jsbarcode library directly in browser memory, it produces high-precision, scannable barcodes for retail packaging, warehouse inventory, and shipping labels without watermarks.

  • Generate standard barcode formats: CODE 128, EAN-13, UPC-A, CODE 39, ITF-14, MSI, and Pharmacode.
  • Customizable bar width (1-4px), height (40-140px), background color, bar color, and quiet-zone margins.
  • Toggle human-readable text label display below the barcode bars.
  • Instant dual export options: download infinitely scalable vector SVG or high-DPI raster PNG images.
  • Built-in format presets with sample product codes for rapid testing and formatting.

How does Barcode Maker work?

The input string is validated against format-specific character encoding rules (e.g. numeric check digits for EAN/UPC, ASCII for Code 128). JsBarcode translates digits into binary bar and space sequence modules.

The sequence is rendered onto an SVG element with exact vector path definitions. Raster export converts the SVG into an offscreen canvas for high-resolution PNG generation.

100% private: all processing happens locally in your browser using client-side WebAssembly, HTML5 Canvas, and modern Web APIs. Your files are never uploaded to any server.
