What barcode formats are supported?

CODE128, EAN-13, EAN-8, UPC-A, UPC-E, ITF-14, and CODE39 are supported. CODE128 works with any text; EAN/UPC formats require numeric-only input of the correct length.

Can I download the generated barcode?

Yes. Click the Download button to save the barcode as a PNG image file ready to use in print or digital materials.

Is my data sent to a server?

No. Barcode generation uses JsBarcode running entirely in your browser. The text you encode into a barcode is processed locally — nothing is transmitted to any server.

What is the difference between EAN-13 and CODE128?

EAN-13 encodes 12 digits plus a check digit and is the standard for retail product identification worldwide. CODE128 encodes any ASCII text including letters, numbers, and symbols, making it more flexible for internal use cases like ID badges and inventory labels.
