Preguntas frecuentes
Is my input sent to a server?
No. The barcode is generated entirely in your browser — your input is never uploaded, stored or logged.
What can Code 128 encode?
All 128 ASCII characters: uppercase and lowercase letters, digits 0–9 and common symbols. It's compact and widely supported.
Is there a length limit?
There's no fixed limit, but very long values produce wide barcodes that are harder to scan. Keep it reasonable.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
