Barcode Generator FAQ

What barcode format should I choose?

Code 128 is a flexible default for many internal labels, while EAN-13 and UPC-A are commonly used for retail product codes.

Can I print barcodes created here?

Yes. Preview the barcode at the size you need, then export PNG or SVG for your print workflow.

What text lengths are supported?

It depends on the selected format. Retail formats like EAN-13 and UPC-A require fixed lengths, while formats such as Code 128 are more flexible.

Should I show the text below the barcode?

Human-readable text is useful on many labels because it lets people verify the encoded value when a scanner is not available.
