Create a barcode in seconds. Enter your value, pick a format like CODE128, EAN-13, or UPC, and download a sharp SVG — all generated locally in your browser.

Who the Barcode Generator is for

Retailers, makers, and developers generating barcodes for products, labels, or testing.

How to use the Barcode Generator

  1. Type your values into the fields above — pick your currency or units where the calculator offers them.
  2. Results update automatically as you type; there's no submit button and nothing is sent to a server.
  3. Adjust any input to compare scenarios, then copy the result with a single click.

How it works

Your value is encoded into the bars and spaces defined by the chosen barcode symbology (CODE128, EAN, UPC, …) and rendered as a scalable SVG you can download.

Features

  • Many formats (CODE128, EAN, UPC…)
  • Crisp scalable SVG
  • Download in one click
  • Runs in your browser

Choosing a barcode format

Different barcode symbologies suit different uses: CODE128 packs the most data and handles letters and numbers, EAN-13 and UPC are the retail product standards (and need a fixed number of digits), and CODE39 is common in industry. Pick the format your scanner or system expects, enter a valid value, and export a scalable SVG.

Frequently Asked Questions

Which barcode format should I use?

CODE128 is a great general choice for text and numbers. Use EAN-13 or UPC for retail products (they require a set number of digits).

Why won't my barcode appear?

The value probably doesn't fit the chosen format — for example, EAN-13 needs 12–13 digits. Check the format's requirements or switch to CODE128.

Is this calculator free and private?

Yes. It's completely free with no signup, and every calculation runs locally in your browser, so your numbers never leave your device.
