Key features

  • Supports general-purpose CODE128, 12- or 13-digit EAN-13, 11- or 12-digit UPC-A, and uppercase-oriented CODE39.
  • Accepts EAN-13 and UPC-A input without the check digit and lets the renderer complete it.
  • Can show or hide the human-readable value below the bars.
  • Downloads a vector SVG or a white-background PNG rendered at three times the preview dimensions.

How to use

  1. Choose a barcode format and enter a compatible value.
  2. Set whether the value should appear and inspect the preview.
  3. Download the barcode as SVG or PNG.

Examples

    Encode inventory numbers or asset identifiers as CODE128 or CODE39 barcodes.

Privacy

Validation, barcode rendering, and SVG or PNG conversion run in your browser.

Requirements

EAN-13 and UPC-A require the supported numeric lengths; CODE39 accepts uppercase letters, digits, spaces, and a limited symbol set.
