Generates a barcode (CODE128, EAN, UPC and more).
The Barcode Generator turns any text or number into a scannable barcode image right in your browser. It supports common formats including CODE128, CODE39, EAN13, EAN8, UPC, ITF14, MSI, pharmacode, and codabar, and lets you download the result as a PNG.
