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:
- It may be that the PDF has a password applied to it. Often, PDF's have an "Owner Password" which is needed to parse or modify the PDF in any way. This article can help to determine if this is the case: https://security.stackexchange.com/questions/85465/determine-security-of-a-pdf-file
- It is possible that the PDF file is corrupted: Please check file for corruption or validity by a 3rd party at: https://www.pdf-online.com/osa/validate.aspx
- If the above steps have not supplied an answer, please contact firstname.lastname@example.org and make a simple, detailed bug report, including the referenced PDF as an attachment.
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.
