Best Free Bulk Barcode Generator (No Limits, No Login)

Most online barcode generators let you create one barcode at a time. If you have 50, 500, or 5,000 products, that's simply not practical. Here's how to generate bulk barcodes from a spreadsheet in seconds — completely free.

The Problem with One-at-a-Time Generators

Most free barcode tools online generate a single barcode per page. You paste a value, download an image, repeat. For 100 products that's 100 steps. For 1,000 products it's simply not feasible. What you need is a bulk barcode generator that processes your entire product list at once.

How Bulk Generation Works

A bulk barcode generator takes a spreadsheet (Excel or CSV) as input, reads every row, and produces a barcode for each one. The output is typically a PDF where each page or label section contains one barcode, ready to print on label sheets.

With BarcodeMaker, this process is entirely browser-based — your data never leaves your computer, which matters when you're handling sensitive product or inventory data.

Step-by-Step: Generate Bulk Barcodes

1. Create or export your product list as Excel (.xlsx) or CSV
2. Make sure one column contains the barcode/SKU values
3. Upload the file at barcodemaker.xyz/upload
4. Select the barcode column and any label text columns
5. Click "Generate PDF" — all barcodes are created at once
6. Download the PDF and print on standard label sheets

What Barcode Format is Used?

BarcodeMaker generates Code 128 barcodes, which are the most widely supported format for retail, logistics, and inventory management. Code 128 can encode any alphanumeric string, making it compatible with virtually all barcode scanners.
