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.
We tested small and multi-page spreadsheets, checked empty and invalid rows, and confirmed that pagination and PDF generation remain inside the browser.
The Problem with One-at-a-Time Generators
Most free barcode tools generate a single barcode per page. For 100 products that's 100 steps, each requiring you to type or paste a value, click generate, save an image, then repeat. What you need is a bulk barcode generator that processes your entire product list at once — reading all rows simultaneously and packaging them into a single print-ready PDF.
How BarcodeMaker Handles Bulk Generation
BarcodeMaker reads your entire spreadsheet in one pass. It generates a Code 128 barcode for every row that has a value in the barcode column, then lays them out 24 per A4 page, creating as many pages as needed. A file with 240 products produces a 10-page PDF automatically. The entire process happens in your browser, so the speed depends on your device — most files under 1,000 rows complete in under five seconds.
Step-by-Step: Generate Bulk Barcodes
- Export your product list as Excel (.xlsx) or CSV
- Make sure one column contains barcode or SKU values for every row
- Go to barcodemaker.xyz and upload your file
- Select the barcode column from the dropdown — other columns are optional
- Click "Generate PDF" — all barcodes are created at once
- Download the multi-page PDF and print on label sheets
Preparing Your Spreadsheet for Bulk Output
For best results, each row should have a non-empty barcode value. Rows with empty barcode cells are skipped. Make sure barcode values are stored as text, not formulas or special-format cells — if your SKU column shows "#VALUE!" errors, clean the data before uploading. Remove any merged cells, which can confuse the column parser.
What Barcode Format is Used?
BarcodeMaker generates Code 128 barcodes, which can encode the full ASCII character set — letters, numbers, and most symbols. This makes it suitable for internal inventory codes, SKU numbers, warehouse bin labels, and asset tracking. Code 128 is not a globally registered retail barcode format (that would require GS1 registration), but it is the right choice for internal bulk labeling workflows. Scanner reliability depends on print quality, symbol size, contrast, and quiet zones.
Typical Bulk Use Cases and Row Counts
- Small retailer new season inventory: 50–300 rows, single-run PDF
- Amazon FBA prep — label hundreds of units per SKU: 100–500 rows
- Warehouse bin labels for an entire facility: 200–2,000 rows
- Library book catalogue import: 500–5,000 rows
- Event ticket batch: 100–1,000 rows
Who Is This For?
- Amazon FBA sellers who need to label hundreds of SKUs before shipment
- Small retailers tagging new inventory before it goes on shelves
- Warehouse managers batch-printing location and bin labels
- Event organizers printing ticket barcodes at scale
- Schools and libraries managing catalogues with physical labels
Printing Large Batches Safely
For large print runs, always print one test page first and scan several barcodes before committing to the full batch. This catches scaling and alignment issues before you waste a full sheet of label paper. Load your label sheets so they feed correctly with the label side facing the right direction for your printer model.
