What Is a Barcode Generator?

1D barcodes are the parallel-line codes you see on retail packaging, inventory tags, shipping labels, and ID badges. Different formats trade character set against density:

• Code 128 encodes any ASCII text and dominates internal inventory and logistics labelling — variable length, three sub-modes (A, B, C) the encoder auto-selects. • EAN-13 / EAN-8 are the global retail standards on supermarket products outside North America. • UPC-A is the 12-digit North American sibling of EAN-13.

This tool validates the input for each format (length, digit-only where required, check digit for EAN/UPC) and renders the symbol locally with a pure-JavaScript encoder — nothing leaves the browser. For UPC-E specifically, use the dedicated UPC tool which exposes the compressed variant.

Frequently Asked Questions

What barcode formats are supported?
Code 128, EAN-13, EAN-8, and UPC-A. UPC-E lives in its own dedicated tool.
What's the difference from QR codes?
Barcodes are one-dimensional and store less data; QR codes are 2D and store more. Use barcodes for products and inventory.
Can I use these for retail?
EAN and UPC are valid retail formats, but you need a GS1-assigned company prefix to register with major retailers.
