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.
How does the checksum work?
EAN-13's 13th digit is a check digit computed from the first 12. Enter 12 digits and it's added automatically; enter 13 and it's verified.
What if my code is invalid?
A clear error is shown if the value isn't 12–13 digits or the check digit doesn't match.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
