A valid product *number* and a scannable barcode *image* are two different things. This renders the image from a code you provide, in CODE128, EAN-13, EAN-8, UPC, ITF-14, CODE39 or Codabar, and downloads it as a PNG ready for a label.
When you'd use this
Printing test labels for a warehouse or QA process, or generating a scannable barcode image for a product listing or shipping label without needing design software.
CODE128 accepts arbitrary text, not only digits, which makes it the right choice for internal SKUs or tracking codes where a retail-standard numeric format like EAN-13 or UPC doesn't apply.
Common errors
Choosing EAN-13, EAN-8, UPC or ITF-14 requires a code of the exact right length with a valid check digit. If your code doesn't validate, generate or fix it with the GTIN Converter or the EAN/UPC Generator first, then bring the corrected code back here to render.
CODE39 and Codabar are more permissive about input, but they produce wider barcodes for the same content. Where a label has limited space, CODE128 is usually the more compact choice for non-numeric data.
Frequently asked questions
Which barcode format should I use?
For retail products, EAN-13 or UPC-A (whichever your market/scanner expects) is the standard. For internal tracking, warehouse, or logistics use where the code isn't a registered retail product number, CODE128 is the most flexible general-purpose choice.
Will this validate my code before rendering it?
Yes for the check-digit-based formats (EAN-13, EAN-8, UPC, ITF-14). An invalid code there won't produce a scannable barcode, since the check digit is part of what a real scanner verifies. CODE128, CODE39 and Codabar don't use a GS1 check digit, so any text within their supported character set will render.
Can I use this for a real product going to retail?
The rendering itself is standard and scannable. For retail use, though, the underlying number still has to be a real, licensed GS1 code. This tool renders whatever code you give it; it makes no check that the number is registered to you.
