What is a barcode generator?

A barcode generator converts text or numbers into a machine-readable barcode image. This free tool supports Code128, EAN-13, EAN-8, UPC-A, Code39, ITF-14, and Codabar formats. Everything runs in your browser — nothing is uploaded to a server.

Which barcode format should I use?

Use Code128 for general text and numbers (most flexible). Use EAN-13 or UPC-A for retail product labels. Use EAN-8 for small product labels. Use Code39 or Codabar for asset tracking and ID cards. Use ITF-14 for shipping cartons.

Can I download the barcode as a vector SVG?

Yes — click Download SVG to get a lossless vector file that scales to any size without losing quality. You can also download a PNG for use in documents or on the web.

Is this barcode generator free?

Completely free. No limits, no sign-up, and no watermarks. All processing happens in your browser, so your data never leaves your device.

How do I generate an EAN-13 barcode?

Select EAN-13 from the format dropdown and enter your 12-digit number — the check digit is calculated automatically. Download as SVG or PNG instantly.

What is the difference between EAN-13 and UPC-A?

EAN-13 is a 13-digit international standard used worldwide. UPC-A is a 12-digit standard used primarily in North America. EAN-13 is a superset of UPC-A — most scanners can read both.
