What is a Barcode?

A barcode is a machine-readable representation of data using parallel lines (1D) or patterns (2D). Linear barcodes encode numbers or text that can be scanned by laser or camera-based readers, commonly used in retail, logistics, inventory management, and healthcare.

Frequently Asked Questions

Can I use these barcodes commercially?

Yes. Generated barcodes are free to use for any purpose. However, for retail (EAN/UPC), you need to register your own numbers with GS1.

Which format should I choose?

Code 128 for general use, EAN-13 for retail products, Code 39 for industrial applications, and ITF-14 for shipping containers.

Why is my barcode not generating?

Each format has specific input requirements. EAN-13 needs exactly 12-13 digits, UPC needs 11-12 digits, Pharmacode needs 3-131070.

What's the difference between PNG and SVG?

PNG is a raster image (fixed resolution). SVG is a vector format that scales to any size without losing quality - ideal for print.
