How to use: Bulk Barcode Generator

Generate hundreds of barcodes at once (Code128, EAN-13, EAN-8, UPC-A, Code39, ITF-14, QR) from a list or CSV/Excel, export as ZIP of PNGs or an A4 label sheet PDF. Everything happens inside your browser on your own device. Your files, numbers and text are never uploaded, there are no accounts, cookies or trackers, and closing the tab removes the data.

Common uses

Step by step

  1. Paste codes one per line, or upload a CSV/XLSX and pick the column.
  2. Choose format, size and an optional label column.
  3. Download a ZIP of PNGs or a printable A4 label PDF (e.g. 3×8).

Worked example

For example, paste 200 product codes, choose Code128, and download a ZIP of PNGs or an A4 label sheet PDF. EAN and UPC codes need a valid check digit.

Tips for better results

Test the output before you rely on it, for example scan a QR code or barcode with your phone before printing many copies. The page is designed for phones first, so it works on a 375-pixel screen as well as on a desktop.

Good to know

The result is created with standard, well-tested methods and can be downloaded or copied straight away. Nothing is stored on a server, so keep your own copy of anything you will need again, such as a password or a set of codes.

Why a browser-based tool?

Many online tools upload whatever you give them to a remote server, process it there and send it back. That is slower on a weak mobile connection and means a copy of your document, photo or figures sits on someone else’s computer. Free Adawat works differently: the code is downloaded once, then the work happens on your phone or computer. That keeps personal papers such as passports, visas, salary slips and contracts private, and it also means there is no queue, no file count limit and no waiting for a download link.

Is Bulk Barcode Generator free?

Yes. It is completely free, with no sign-up, no watermark and no daily limit. The only limit is your device memory for very large files.

Does it work on a phone?

Does it work without internet?
