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.
Which formats are supported?
EAN-13, EAN-8, UPC-A, Code 128, Code 39 and ITF-14. Dedicated pages exist for each, plus ISBN.
Can I export SVG?
Yes. SVG is a clean vector format that stays sharp at any size — ideal for printing. PNG is also available.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
