Hello Warrens,
With the subscription of Adobe ExportPDF service, you can converts most of the PDF files available today, including PDF files containing scanned documents. There are a few types of PDF files that cannot be converted, however. These types include the following:
- PDF files that require a password to open the document
- PDF files that have permissions applied to prevent printing, copying, or altering of the content
- PDF Portfolios
- PDF files generated from Adobe Illustrator.
For detailed information, you may refer to FAQ | Adobe Export PDF, Document Cloud
If you are the owner of the PDF file and have added the security settings that is added the password, you need to subscribe to Acrobat Pro DC license/subscription to remove the password and then you may export the PDF file to Word.
For plan and pricing of Acrobat, you may refer to Plans and pricing | Adobe Acrobat DC
Feel free to update this discussion for any further assistance.
Thanks,
Anand Sri.
