Pdf files not secure with third party sites
PDF files cannot be protected from converting to other document types.Even after using Pro version,encrypting with password, others could convert our documents to word file using 3rd party sites.If using encrypting with certificate,conversion is not possible but others cannot view our document.What is the solution to secure our pdf files allowing others to view but not to print,edit or convert?

Thanks for reporting this. Our team is investigating ways to address your concern. The current issue is due to the fact that once a PDF is opened then it is the sole responsibility of the application that has opened the PDF to protect the content. Once the PDF is opened in an app then the app has full control over the content and this is why some 3rd party apps ignore the permissions and allow copy/export. We however wanted your opinion on one of the line of thought that can be perused. To protect your content from being exported will you be OK to protect you document such that the document only opens in Adobe/other supported viewers? This way only supported viewers will have access to the content. If consumers of your PDF try to open such protected PDF then they will be presented with a message to download a supported viewer to be able to open your file.
