FAQs
How is Code128 different from EAN-13?
EAN-13 only encodes 13 numeric digits and is used for retail products. Code128 can encode any ASCII text — letters, numbers, and punctuation — making it far more flexible for logistics and inventory use.
Is there a length limit?
There's no hard limit, but very long text produces a wide, dense barcode that may be harder for some scanners to read reliably — shorter codes scan more consistently.
Is my data uploaded anywhere?
No — the barcode is generated entirely client-side in your browser using the jsbarcode library.
