About the Barcode Generator

The Barcode Generator generates Code 128, EAN-13, UPC-A, Code 39 and ITF barcodes as PNG or SVG with human-readable text. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Labelling stock in a small warehouse.
  • Producing a barcode for a product mockup.
  • Printing asset tags.
A generated EAN or UPC barcode is only valid in retail if the number was issued to you by GS1. Making up a number produces a scannable barcode that belongs to somebody else, or to nobody.
