About Bulk Barcode Generator
Free browser-based barcode tools for Code 128B, Code 128C, Data Matrix, QR and UPC-A — generated locally, never uploaded.
Last updated: 2026-09-18
Bulk Barcode Generator is an independent, browser-based toolbox for producing barcodes in quantity.
What the tools do
You can turn a pasted list, a single value or a spreadsheet column into finished barcode images: Code 128B and Code 128C linear barcodes, Data Matrix and QR codes, and UPC-A retail symbols — each downloadable as vector SVG or PNG, individually or as a ZIP batch. The Excel tool reads XLSX, XLS and CSV files directly.
How it works
All generation happens inside your browser. When you press Generate, JavaScript running on your device renders the barcodes — there is no server-side rendering, no queue and no upload. Your values, spreadsheets and results exist only in your browser tab and disappear when you close it.
That design decision drives everything else: no accounts, no watermarks, no tracking of your data, and no waiting.
Scope and limits
This site creates barcode images from values you provide. It does not issue, register or license GS1 GTIN/UPC numbers, and its Data Matrix output is standard rather than GS1-formatted. Current batch limits are 100 values per pasted list and 500 rows per spreadsheet file.
