常见问题
Is my input sent to a server?
No. The barcode is generated entirely in your browser — your input is never uploaded, stored or logged.
Is UPC-A the same as EAN-13?
They are closely related — a UPC-A is essentially an EAN-13 with a leading 0. EAN-13 is used worldwide; UPC-A mainly in North America.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
