Create a barcode image from a value using CODE128, EAN-13, UPC or CODE39. Choose a format that matches the reader and workflow that will consume it.
How to use this tool
- Enter the value and select the barcode format.
- Generate the preview and correct any validation error.
- Download the PNG, print at a suitable size and test it with the intended scanner.
How to interpret the result
EAN-13 requires 13 digits and UPC requires 12; valid check digits and format restrictions still apply. A generated barcode does not assign an official retail product number or register it in a product database.
Frequently asked questions
Can I use any text for EAN-13?
No. Numeric retail formats have specific lengths and checks. Use an appropriate general-text symbology such as CODE128 for compatible non-retail workflows.
