IronPDF can not open / parse a specific PDF file

If IronPDF can not open a specific PDF file, we want to know about it.

This .NET Exception message may be seen: "PDF can not be parsed as a valid PDF. May be an incorrect file type or a password is required."

How to resolve the issue

The PDF standard is constantly changing. It is a great help to be able to add any new cases to our unit tests, so that this compatibility issue can be resolved once and for all.
