Frequently Asked Questions

What barcode formats does this tool support?

The tool supports CODE128, EAN-13, EAN-8, UPC-A, UPC-E, CODE39, ITF-14, and MSI barcode formats. CODE128 is the most versatile and is recommended for general use.

Is the barcode generated on my device or a server?

All barcode generation happens entirely in your browser using the JsBarcode library. No data is sent to any server and nothing is stored.

Can I use the barcode for commercial purposes?

Yes. The SVG barcodes you generate are yours to use however you wish, including in commercial products, packaging, and print materials.

What is the difference between EAN-13 and UPC-A?

EAN-13 is the international standard used widely outside North America and encodes 13 digits. UPC-A is used primarily in the United States and Canada and encodes 12 digits.

Why does my barcode show an error?

Some formats have strict data requirements. EAN-13 requires exactly 13 digits, UPC-A requires exactly 12 digits. CODE128 accepts any text or numbers and is the most flexible.

Can I change the size of the barcode?

Yes. Use the width and height fields to set the dimensions of the generated barcode SVG. You can also toggle whether the human-readable text label is shown.

What file format is the download?

The barcode is downloaded as an SVG file, which is a vector format that scales to any size without loss of quality.

Does this tool work offline?
