UPCgen

UPCGen is the simplest barcode generator on the internet. We render and generate valid UPC, EAN, ISBN, GTIN, ITF-14, Code 128, FNSKU, and Data Matrix barcodes — for sellers, warehouses, publishers, and anyone who needs a usable code in seconds.

Why we built it Every existing barcode tool is either bloated software, a confusing checkbox-soup of options, or pretends to issue "free" UPCs that collide with real registered products. We wanted one clean page that generates a valid code, downloads cleanly, and is honest about when you need a real GS1 number.
