Frequently asked questions

Is my barcode data uploaded?

No. Barcodes are rendered locally with JsBarcode on a canvas in your browser and never sent to a server.

Which formats are supported?

CODE128, CODE39, EAN-13, EAN-8, UPC, ITF-14, Codabar, and MSI. Numeric retail formats (EAN/UPC) need the correct digit length; CODE128 accepts most text.

Why did generation fail for EAN or UPC?

Those formats require a specific number of digits (and a valid check digit when provided). Try CODE128 for free-form text, or use a valid product code.
