Frequently asked questions
Is the barcode generator really free?
Yes. Single, batch and label sheet generation are all free, with no account and no sign-up.
Do my barcode values leave my device?
No. Barcodes are generated in your browser. The only network load is the barcode and ZIP library files themselves; your values are never sent to a server.
What barcode formats are supported?
Code128, EAN-13, UPC-A and Code39. Each format validates your input first and shows a plain error instead of a wrong barcode.
How does batch mode work?
Paste one value per line, pick a format, and generate all at once. You can download each barcode as a PNG or all of them together as one ZIP file.
How do I print labels?
Use the label sheet view, which lays your batch out as a 30-label grid on an A4 sheet, then use your browser's print function. It is a generic grid and is not tied to any specific label brand.
