How it works
Make a barcode label in three steps
02
Choose the format
Open Advanced options to select Code 128, Code 39, EAN-13, UPC-A, ITF-14, or Codabar.
03
Review and download
Check that the preview renders, adjust its size if needed, and download a PNG image.
Example
A warehouse bin label
For a bin called RACK-A12, choose Code 128 and enter that value. The preview includes readable text when that option is enabled, so staff can scan the bars or read the label directly.
Questions
Barcode generator details
Which barcode type should I choose?
Code 128 is a flexible choice for general labels. EAN-13 and UPC-A are commonly used for retail products and require values in their expected format. Choose the format required by the system or scanner that will read the barcode.
Why is my value rejected?
Some barcode formats accept only certain characters or lengths. Try Code 128 for general text, or check the number and required checksum for a retail format such as EAN-13 or UPC-A.
What can I download?
This generator downloads the current barcode as a PNG image. Adjust the width and height first if you need a larger label image.
Practical guide
Read the Product identifier checklist
Protect identifier columns as text, review values that may have been changed by a spreadsheet, and validate before you generate labels.
