Barcode Generator
Generate a scannable Code 128 barcode from any text or product code, as a crisp vector file.
Enter a value above to generate your barcode.
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.

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.
