SVG or PNG output
Choose vector SVG or high-quality PNG files for every generated row.
Useful file naming
Duplicate values receive clear, unique filenames in the ZIP.
Batch rules & output
Keep the barcode type, validation result, generated graphics, and downloads clear at every step.
Supported formats
Use Code 128, EAN-13, UPC-A, or ITF-14 only in this batch tool.
Check digit handling
EAN-13, UPC-A, and ITF-14 source values can calculate their final check digit.
One type per batch
Changing the barcode type revalidates every row and clears generated files.
Graphic output only
This tool creates barcode graphics. It is not a label, GS1, FNSKU, or Excel workflow.
Bulk Barcode Generator creates barcode graphics from individual values. It does not create labels, process product fields, accept Excel or CSV uploads, issue GTINs, assign GS1 company prefixes, or guarantee retailer, warehouse, or printing acceptance.
Frequently asked questions
Find answers about batch input, validation, output files, and limits.
Which barcode types can I generate in bulk?
Bulk Barcode Generator supports Code 128, EAN-13, UPC-A, and ITF-14. A batch uses one barcode type at a time.
How many barcode values can I add?
You can add up to 100 non-empty barcode values per batch. A larger pasted list is blocked instead of being shortened.
Can I paste values with blank lines?
Yes. Blank lines are ignored. Nonblank values are kept as entered so whitespace or invalid characters are shown as row-level validation issues.
What happens when some rows are invalid?
Invalid rows show their specific error and are excluded. You can still generate and download the valid rows in the same batch.
Does Barlora calculate check digits?
For EAN-13, UPC-A, and ITF-14, you can enter a value one digit short and Barlora calculates the final check digit. Complete values are validated.
Can I download the results as a ZIP file?
Yes. After generation, Barlora creates one ZIP containing the generated valid SVG or PNG files with unique filenames.
Can I upload Excel or CSV files?
Use Barcode from Excel to import .xlsx or .csv files, select a barcode column, and generate valid barcode files.
