Frequently asked questions

Common questions people ask before using this tool.

What is a free online barcode generator?

It is a browser tool that encodes your data into standard barcode symbologies and lets you preview and download a scannable image without installing desktop software.

Which barcode format should I use?

Use the symbology required by your retailer, POS system, marketplace, or internal inventory platform — CODE128 for general alphanumeric data, EAN-13 or UPC-A for retail product codes where applicable.

Can I use generated barcodes commercially?

You may use the images for internal tests and mockups, but registered retail product identifiers must come from the proper issuing authority when selling goods.

Can I download the barcode image?
