About this barcode generator
This barcode generator turns any text or number into a scannable Code 128 barcode rendered as clean inline SVG. Code 128 is a high-density format widely used for shipping labels, inventory, and packaging, and it supports the full range of printable ASCII characters. Type your value and the barcode updates live, complete with the required checksum and quiet zones so real scanners can read it. Choose a bar width, toggle the human-readable text underneath, and copy the SVG markup to drop into labels, documents, or your own designs. Everything is encoded locally in your browser, so nothing is uploaded.
