PDF-Validation - explanation

The uploaded file is processed by a pdf-validation tool. This tool tries to validate the file against a profile from IEEE to check for IEEE Xplore compatibility.

If your file is not a pdf document, the report will be meaningless. But refer to the conference information page, if non pdf documents are allowed.

Different States
