What barcode format should I use?

Use EAN-13 or UPC-A for retail products (they are required by most point-of-sale systems). Use Code128 for shipping labels, inventory, and general-purpose encoding — it supports the full ASCII character set with high data density.

What is the difference between 1D and 2D barcodes?

1D barcodes (like Code128 and EAN-13) encode data in parallel lines of varying width. They hold less data but are read by simple laser scanners. 2D barcodes (like QR codes) use a grid of squares and hold much more data but require a camera-based scanner.

Is this tool free to use?

Yes. This tool runs entirely in your browser with no account required. Your data never leaves your device.

Can I use generated barcodes for commercial products?

The barcode image itself is yours to use freely. However, retail barcodes (EAN-13, UPC-A) require a valid GS1 prefix registered to your company. The generator creates the visual barcode but does not assign or validate GS1 numbers.

Does this work on mobile?

Yes. The tool is fully responsive and works on any device with a modern browser. Generated barcodes can be downloaded directly to your phone.
