À propos de Barcode Generator

This barcode generator creates Code 128B barcodes from any ASCII text (characters 32-126). Code 128 is a high-density linear barcode symbology used in shipping labels, inventory management, product identification, and logistics. Enter your text, adjust bar width and height with sliders, optionally show the human-readable text below the barcode, and download the result as a PNG image. All encoding and rendering happens client-side using HTML Canvas — no data leaves your browser.
