FAQ

Which barcode types are supported?

Over 100 symbologies: Code 128/39/93, EAN-8/13, UPC-A/E, ITF, GS1-128, GS1 DataBar, Data Matrix, PDF417, Aztec, postal codes like USPS Intelligent Mail, plus HIBC healthcare variants.

Can the tool compute check digits for me?

Yes. For EAN-13, EAN-8, UPC-A and Code 128 family, enter the data without the check digit and it is added automatically.

How do GS1 barcodes work?

Wrap Application Identifiers in parentheses — e.g. (01)09521234543213(3103)000123 — and keep “Parse GS1 AIs” enabled so the tool converts them to FNC1 groups.

Which export formats are available?

PNG, JPEG, WEBP and SVG — all rendered locally in your browser.
