What Is a Barcode Generator?

A barcode generator encodes data into a machine‑readable visual pattern that can be scanned by barcode readers and smartphone apps. Barcodes are essential for retail, inventory management, shipping, and product labeling. This tool supports nine popular barcode formats: EAN‑13, UPC, Code128, Code39, EAN‑8, ITF‑14, MSI, Pharmacode, and Codabar. It uses the JsBarcode library, a lightweight, dependency‑free JavaScript library that renders barcodes as SVG elements. All processing happens locally in your browser — nothing is ever uploaded to a server.

How to Use

Enter your data in the text field — the content you want to encode in the barcode.

Customize the barcode — adjust width, height, font size, colors, and text display options.
Click "Generate Barcode" — the barcode appears instantly in the preview panel.
Download the barcode as an SVG image with the Download button, or clear everything with the Clear button.
