What is Barcode Generator?
The Barcode Generator creates Code128 barcodes from text or numbers you enter. Code128 is a high-density barcode format that supports all ASCII characters. The tool renders the barcode as an image that you can download as PNG or SVG. It is useful for creating labels, inventory tags, and product codes. All processing happens in the browser.
How does Barcode Generator work?
This tool encodes your input text into Code128 barcode format using a JavaScript barcode library. It calculates the check digit, renders the barcode pattern as a canvas image, and provides download options. The output is scannable by standard barcode readers.
