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.
