Barcode Generator

The Barcode Generator creates barcodes in the **Code 128** format, one of the most versatile and widely supported standards by industrial and commercial scanners. Code 128 encodes all printable ASCII characters — letters, numbers and symbols — in vertical bars of varying widths, producing a compact and reliable representation.

To generate a barcode, simply type the desired text in the field. The code is rendered instantly. You can adjust the **bar width** (from 1 px to 4 px, for a more compact or more readable result), the **height** of the barcode (from 60 px to 200 px) and choose whether the text is printed below the bars. When the result looks right, click "Download PNG" to save the image.

Practical use cases include: creating labels for internal products in small businesses, generating codes for manual inventory tracking, printing identifiers on event materials, creating custom tracking codes, and testing integration with barcode readers in POS systems.

Rendering is done by the JsBarcode library in the browser itself. No data is sent to external servers and no account is required.
