About this tool
Barcodes are machine-readable representations of data used across retail, logistics, healthcare, and manufacturing. This tool lets you create barcodes in four widely-used formats -- Code 128, EAN-13, UPC-A, and Code 39 -- directly in your browser.
All generation happens client-side using the JsBarcode library. Nothing is sent to a server, so your data stays private. The output is a crisp SVG that scales to any size without losing quality, making it ideal for both digital use and print.
