System FAQ

How do I generate a barcode for my product for free?

Select your barcode type (EAN-13 for retail products, CODE128 for general use), enter your barcode number, adjust width and height, then click Generate. Download as SVG or PNG.

What barcode format should I use for retail products?

EAN-13 is the global standard for retail products sold internationally. UPC-A is used mainly in North America. CODE128 is versatile for internal use, shipping, and logistics.

Why should I use SVG format for barcodes?

SVG is a vector format — it scales to any size without losing quality. A barcode on a tiny label will scan just as well as one on a large banner. PNG barcodes can become blurry when enlarged for large-format printing.

Can I generate barcodes for Amazon FBA?

Yes. Amazon FBA requires FNSKU barcodes (CODE128 format). Enter your FNSKU code, generate in CODE128 format, download at high resolution, and print labels at 1x2 inch size.

Does my barcode data get stored anywhere?

No. Barcode generation runs entirely in your browser. Your product codes and data never leave your device.
