Question 1

What barcode types can I generate?

Accepted Answer

CODE128 (most common), EAN-13 (retail products), UPC-A (US retail), EAN-8, CODE39, ITF-14, MSI, Pharmacode and Codabar. All encoding runs in your browser using JsBarcode.

Question 2

Can I download the barcode as SVG?

Accepted Answer

Yes. You can download your barcode as PNG (raster, good for print) or SVG (vector, infinitely scalable). SVG is best for packaging and high-resolution printing.

Question 3

How do I make an EAN-13 barcode valid?

Accepted Answer

EAN-13 requires exactly 12 or 13 digits. The 13th digit is a checksum — if you enter 12 digits the tool calculates it automatically. UPC-A uses 11 or 12 digits with the same checksum logic.

Question 4

Is the barcode generator free?

Accepted Answer

Yes, completely free. No signup, no watermark, no limit. Everything runs in your browser — your data never leaves your device.
