Make barcodes in your browser
This free barcode generator creates Code 128, Code 39, EAN-13 and UPC-A barcodes locally in your browser. It can be useful for internal inventory labels, asset tags, stock lists and product mockups.
Retail point-of-sale systems may require officially assigned GTIN/EAN/UPC numbers. This tool validates barcode structure but does not assign product identifiers or certify that a number is registered to your business.
Always scan-test the downloaded barcode at its final printed size. Keep clear space around the bars, use strong contrast and avoid stretching the image. Your entered value is not uploaded.
