Barcodes encode text or numbers as a pattern of parallel lines that scanners can read instantly, widely used for inventory, product labeling, and tracking. This tool generates a CODE128 barcode — a flexible, widely supported format that can encode letters, numbers, and many symbols — directly in your browser.
Type any value and the barcode updates live; when it looks right, download it as a PNG ready to print or embed in a label design.
Because generation happens client-side using a JavaScript barcode library, nothing you type is transmitted anywhere before the image is created.
Because everything runs locally in your browser, results appear instantly and nothing you type or upload is ever sent to a server.

Frequently asked questions
What barcode format does this use?
CODE128, a versatile and widely scannable format that handles the full ASCII character set, commonly used in shipping, packaging, and inventory systems.
Will this barcode work with any scanner?
CODE128 is broadly supported by standard barcode scanners and scanning apps, though for retail products specifically (like UPC/EAN), you'd need a barcode assigned through the relevant standards body rather than an arbitrary generated one.
