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.
ISBN-10 or ISBN-13?
Both work. ISBN-10 is converted to ISBN-13 (prefixed with 978 and re-checksummed), since book barcodes use the ISBN-13/EAN-13 format.
Is the price add-on supported?
No. This generates the main ISBN (EAN-13) barcode only, not the EAN-5 price add-on.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
