What it does

Barcode Generator produces its output in your browser using the platform's own cryptographic random source where randomness matters — not a seeded pseudo-random shortcut. Code 128 barcodes, downloadable as SVG.

When you need it

Whenever you need a value that has to be correct rather than approximately right, and typing one yourself would either be predictable or a formatting mistake waiting to happen.

Limits and caveats

Nothing is generated on a server, logged, or recoverable — if you close the tab without copying the result, it is genuinely gone. Keep anything you intend to rely on in a password manager rather than in this page. Everything happens in your browser, so the file never leaves your device.

How to use the Barcode Generator

  1. Set the options you want.
  2. Your result is generated instantly.
  3. Copy or download it.

Frequently asked questions

Which barcode standard is this?
Code 128 subset B, which covers letters, numbers and common symbols — the usual choice for internal labels and inventory codes.
Why SVG rather than PNG?
Barcodes must stay sharp at any print size. A vector never blurs, so scanners keep reading it.
