Domande frequenti
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 characters are allowed?
Uppercase A–Z, digits 0–9, and the symbols - . space $ / + %. Lowercase letters are not supported by Code 39.
Why is Code 39 wider than Code 128?
Code 39 is lower density (each character takes more bars), so it produces longer barcodes. Use Code 128 for compactness.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
