Bulk Barcode Generator is a free browser-based bulk barcode generation tool, mainly aimed at small shops, warehouses, and online sellers that need to quickly produce large numbers of barcode labels. Its core features are that no software installation is required, no account creation is needed, there is no watermark, and there is no row limit.
In terms of use, this tool is used to generate barcode labels in bulk. Users can paste a SKU list, or import CSV or Excel files, select the desired barcode type, and then download a printable file. It is officially stated that hundreds of labels can be generated in seconds.
Main capabilities include: support for barcode types such as Code 128, UPC-A, EAN-13, QR Code, Data Matrix, and Code 39; support for PNG, SVG, PDF (usable with Avery label sheets), and native ZPL output for Zebra, Rollo, and SATO thermal printers. The tool generates all barcodes locally in the browser, and product data is not sent to a server.
How to use: users can select a barcode type, paste a list of values or upload a file, and then download a print-ready file. It is officially recommended to set scaling to 100% (or "Actual size") before printing, uncheck "Fit to page" or "Fit to printable area," uncheck "Shrink oversized pages" if available, and first download an alignment test PDF to verify positioning.
Regarding specific barcode choices, the official explanation states: Code 128 is suitable for internal inventory, SKU, and warehouse labels, with no registration required; EAN-13 is accepted by almost all supermarkets worldwide and requires GS1 registration; UPC-A is required by most U.S. retailers and Amazon FBA listings and must be purchased from GS1; QR Code can be read natively by any smartphone camera without an app. Amazon FNSKU barcodes can be obtained for free from Amazon Seller Central, and their underlying format is Code 128, so users can paste the FNSKU string and select Code 128 to generate it themselves. For retail store sales, the official guidance notes that a GS1-issued UPC-A (United States) or EAN-13 (international) is usually required, because retailers scan these barcodes at the point of sale, and a self-generated Code 128 cannot be used for retail checkout.
Applicable scenarios include: Amazon FBA sellers, 3PL warehouse operators, small retailers, restaurants printing date-code labels, and manufacturers performing internal SKU tracking.
Limitations and notes: the tool itself does not provide GS1 registration or official UPC/EAN numbers, which must be obtained separately for retail scenarios; barcodes are generated locally in the browser, but specific browser compatibility is not provided; when printing, scaling and page-fit options need to be set correctly to ensure accurate physical dimensions.
