A barcode is just a machine-readable way of storing a short piece of data — a product number, an asset tag, a link. Making one does not need special software or a paid service: a browser can draw a valid barcode in seconds, and the trick is mostly picking the right type for the job.
Choose the right barcode type
The type matters because scanners and standards expect specific data. As a quick guide: use Code 128 for general text or asset tags, EAN-13 or UPC-A for retail products, ITF-14 for shipping cartons, and a QR code for anything you want a phone to scan, like a link. If you are not selling through a retailer, Code 128 or a QR code will usually do.
How to make one
- Open the barcode generator and pick your type. The hint under the box tells you exactly what data that type accepts.
- Type or paste your data. The preview updates as you go.
- Adjust the size and colours if you like, then download it as an SVG (sharp at any size, best for printing) or a PNG.
Making a whole batch
If you need a barcode for every order, ticket or shelf, switch to bulk mode. You can paste a list of values, or just give a number range — say 1 to 500 with a prefix — and get every barcode back in a single ZIP. It is far quicker than making them one by one.
For retail barcodes that must be globally unique (EAN or UPC), the numbers themselves come from GS1, the organisation that issues them. This tool draws a valid barcode from whatever number you provide; it does not assign you an official product number.
