What it does
Generate a scannable Code39 barcode from any letters, numbers, and a handful of symbols (dash, period, space, dollar, slash, plus, percent). Rendered on a canvas in your browser, downloadable as a PNG, ready for inventory labels, event badges, asset tags, or homework projects.
Code39 scans reliably on virtually any barcode reader and prints well at low resolution. For QR-style 2D codes use QR code generator; for smaller assets, favicon generator.
