Frequently Asked Questions

Which symbologies are supported?

EAN-13, UPC-A, and ITF (Interleaved 2 of 5) for common retail and logistics barcodes.

Is the check digit calculated automatically?

Yes. Enter the digits without the check digit (e.g., 12 digits for EAN-13) and it will be computed and validated automatically.

Can I adjust the barcode size?

Bar height and module width are adjustable, and the result downloads as a PNG.

Is data sent to a server?

No. Barcodes are generated entirely in your browser.
