About Barcode Generator
The Barcode Generator is a secure client-side utility designed to create standard Code 39 barcodes. Code 39 is a widely used barcode format for inventory tracking, asset management, and industrial labeling. Our tool lets you generate custom barcodes from numbers and letters, customize their height, and download them as PNG images locally.
How it Works
Type your alphanumeric text into the input box. The tool validates the input and draws the barcode instantly. You can adjust the height slider and click the download button to save the barcode as a PNG image.
Key Features

- Adjustable Height: Customize the vertical size of the barcode.
- PNG Downloads: Save your barcode in high resolution.

Technical Details
The generator uses our custom client-side barcode library. It maps alphanumeric characters to their Code 39 binary stripe representations, calculates the total width, draws the stripes onto a canvas, adds text labels below, and generates a downloadable PNG.
