Is this barcode generator private? Can I use it offline?

Yes on both counts. Barcodes are rendered entirely on your computer with JavaScript — your data never leaves your device, and the tool works offline.

Can I use the generated barcodes commercially?

Yes. The barcodes are generated on your computer and you own the output. Use them for products, labels, or any purpose.

Is the barcode scannable?

Yes. The barcodes are rendered to spec and can be scanned by any standard barcode reader or smartphone app.
