- What is a bulk barcode generator?
- A bulk barcode generator is a tool that lets you create multiple barcode labels at once from a list of values. Instead of generating barcodes one by one, you paste or upload a CSV or Excel file with hundreds of product codes, and the tool outputs all labels as a print-ready PDF or a ZIP of PNG images.
- Is Bulk Barcode Generator really free?
- Yes. Bulk Barcode Generator is completely free, with no hidden fees, subscription tiers, or trial limits. There is no row limit, no watermark, and no account required — ever.
- What barcode formats does it support?
- This free bulk barcode generator supports six common formats: Code 128 (general inventory and internal SKUs), EAN-13 (international retail), UPC-A (US retail and Amazon FBA), Code 39 (legacy scanners), QR Code (URLs and mobile scanning), and Data Matrix (small-label industrial use).
- Can I use this tool with a Zebra thermal printer?
- Yes. In addition to PDF and PNG export, Bulk Barcode Generator can output barcodes as ZPL (Zebra Programming Language) commands that send directly to Zebra label printers — no driver configuration needed.
- Do I need to sign up or create an account?
- No. There is no account or signup required. Open the page, paste your values or upload your file, and download your labels immediately.
- Does my data get uploaded to a server?
- No. All barcode generation happens entirely in your browser using client-side JavaScript. Your product codes, SKUs, or any other data you enter never leave your device.
- What file formats can I import?
- The bulk barcode generator accepts pasted values (one per line) or an uploaded CSV file or Excel spreadsheet (.xlsx / .xls). Any column in the file can be mapped as the barcode value — no reformatting required.
- How do I print barcode labels at the correct size?
- Download the PDF, then open it in any PDF viewer. Set the print scale to 100% (or "Actual size") and disable "Fit to page." Labels are sized to match standard Avery and thermal label sheets at 300 DPI.
- How many barcodes can this bulk barcode generator handle at once?
- There is no row limit. Whether you need 10 labels or 10,000, paste or upload your full list and the bulk barcode generator processes every row. Large batches of several thousand SKUs typically complete in under 10 seconds. Your browser's available memory is the only practical ceiling — and for most product catalogs, that ceiling is never reached.
- Can I add a product name or price below the barcode?
- Yes. When your CSV or Excel file has multiple columns, you can map a second column as the text line printed beneath the barcode bars — for example, a product name, size, price, or SKU description. This gives you a complete label with both machine-readable and human-readable information in a single download.
This bulk barcode generator is a free, browser-based tool built for small shops, warehouses, and online sellers who need to generate barcode labels in bulk — fast, without signup, without watermarks.
Whether you need Code 128 for internal inventory, EAN-13 or UPC-A for retail shelves, QR codes for product pages, or ZPL commands for Zebra thermal printers, just paste your list and download print-ready labels in seconds.
All processing happens locally in your browser — your data never leaves your computer.
