Convert password protected pdf to pdf with new watermark

Hi Support,

I want to convert password protected PDF into PDF with new watermark,header, footer.
The PDF file contains mathematical equations,special character ,charts etc.

Is this functionality available with ASPOSE ?

@vusd001,
If you have the password, then you can decrypt the source PDF document. You need to call a Decrypt method of the Document class. Please refer to this help topic: Decrypt PDF File with Owner Password. You can also modify the headers and footers of the PDF document. Please refer to this help topic: Manage Header and Footer
