Barcode format

Creating a barcode graphic does not issue or register a globally unique product identifier with GS1, retailers, or marketplaces.

How to Generate a Barcode

Select a format, enter a valid value, adjust dimensions, and generate the preview. Your value never leaves the browser.

Supported Barcode Formats

CODE128 supports general text, CODE39 supports a restricted uppercase set, and EAN-13, EAN-8, UPC-A, and ITF use numeric values with format-specific validation.

CODE128 vs UPC vs EAN Barcodes

CODE128 is flexible for internal labels. UPC-A and EAN formats are used for retail identifiers and require valid lengths and check digits.

Downloading and Printing Your Barcode

SVG is best for scaling without blur; PNG is convenient for documents. Test printed output with the scanner and workflow you intend to use.
