Barcode generator

Generate CODE128, EAN13 or UPC with input validation and PNG/SVG downloads.

Each stage has an 8-second deadline. Cancellation prevents publishing the result and terminates the worker; native image decoding or PNG encoding may continue until the browser finishes, with no overlapping native operation allowed.

CODE128: up to 80 printable ASCII characters. EAN13: 13 digits; UPC: 12 digits, with a valid check digit.

How to use

Choose a format. For EAN13 and UPC, enter all digits including the valid check digit; for CODE128, enter the desired text. Process and download.
