Barcode Generator FAQ
Is this barcode generator free?
Yes. You can create barcodes online for free without creating an account, installing software or adding a watermark.
Can I create one barcode or many barcodes at once?
Yes. Use Single barcode mode for one code, or Bulk barcodes mode to enter multiple values and generate them together.
Are my barcode values uploaded to a server?
No. Barcode generation runs inside your browser. The values you enter stay on your device and are not uploaded to a server.
Which barcode formats are supported?
The tool supports CODE 128, CODE 39, EAN-13, EAN-8, UPC-A, JAN and ITF-14. CODE 128 is a good default for most text, SKU, inventory and internal tracking codes.
What is the best barcode format to use?
Use CODE 128 for general text, numbers, SKUs and inventory labels. Use EAN-13, JAN or UPC-A for retail product codes, and ITF-14 for cartons or shipping units.
Can I download the barcode as PNG or SVG?
Yes. You can download barcodes as PNG for quick use and printing, or SVG for scalable vector graphics that stay sharp at any size.
Why is EAN-13, JAN or UPC-A rejecting my value?
EAN-13 and JAN require 13 digits, while UPC-A requires 12 digits. If your value contains letters or has a different length, use CODE 128 instead.
Can I use this barcode generator on mobile?
Yes. The barcode generator works in modern mobile browsers on iPhone and Android. For large bulk barcode jobs, a desktop or laptop may be faster.
