About the Barcode Generator

Create a Code 128B barcode for labels, internal identifiers and test documents without sending the value to a server.

How to use it

  1. Enter printable text or an identifier.
  2. Generate the Code 128B preview.
  3. Verify the value and download the SVG.

Example

An internal order value such as ORDER-2026-001 can be rendered as a scalable label barcode.

Encoding logic

The MVP uses Code Set B, calculates the required weighted checksum and adds the standard start and stop patterns.

Limitations

Printable ASCII is supported up to 80 characters. This tool does not manage inventory, GS1 data or label compliance.
