Free bulk barcode generator
Upload an Excel or CSV list of product numbers, SKUs or asset tags and get a barcode for every row. Download them as a ZIP of images or one printable PDF sheet of labels.
Barcodes for your whole catalogue
Launching a product range or labelling a stockroom? Instead of creating barcodes one by one, put your numbers in a spreadsheet, upload it, and Zonlet generates every barcode in your browser. Invalid rows, such as a wrong EAN check digit, are flagged so you can fix them.
Captions and copies
Add a product name or location above or below each barcode, and set how many copies of each label you need. Leave cells empty to use the defaults from the page.
Ready for print and design
Download numbered PNG files, SVG vector files for packaging artwork, or a PDF sheet to print on regular paper or label stock.

Frequently asked questions
How many barcodes can I make at once?
Up to 10 rows per batch without an account, or up to 100 rows per batch with a free Google sign-in. Run more batches for larger lists.
Which barcode types can I mix in one file?
Code 128, Code 39, EAN-13, EAN-8 and UPC-A. Each row has its own type column.
What happens if a number is invalid?
Zonlet lists the rows with problems, such as the wrong number of digits or an incorrect check digit, so you can correct them before exporting.
Is my product list uploaded anywhere?
No. The spreadsheet is processed in your browser and barcodes are generated on your device.
