Sensitive information requires enhanced protection and Acrobat DC delivers just that.

Its protection covers all fronts so that you can pick the weapon of choice that best fits your needs from password encryption to set up file permissions.

To prevent reviewers from copying, editing, or printing your PDFs, you can:

  • Secure the files from all your Office programs (prevent your PDF from being copied/modified by restricting editing in Microsoft Word, Excel, and PowerPoint)
  • Add passwords (encrypt your PDF file with a certificate or password)
  • Publish Sensitive Information feature (redact, password protect a PDF, and save your file with edit and copy restrictions applied automatically)
  • Customize your protection (create custom security policies to apply PDF password protection and permissions the same way every time)

Adding passwords and permissions to PDF files is easy in Acrobat PRO. Simply follow the steps below:

  • Launch the Acrobat and open your PDF.
  • Go to the Tools menu and select Protect.
  • Choose your preferred protection: restrict editing with a password or encrypt the file with a certificate or password.
  • Set the security method.
  • Click Save to validate your actions.

PDF Anti-Copy

enjoy PDF Anti-Copy

You can stop users from copying PDF text with the help of the PDF Anti-Copy tool.

The program’s approach is quite unusual as it uses GhostScript and its –dNoOutputFonts switch to replace the text with vector graphics.

While the page will look the same, you will not be able to select text anymore. An important downside of the program is how exported documents are not searchable since its text is removed.

Another minus is its size at 4,377KB. On the other hand, the program is easy to use and its interface is quite simple.

After clicking the loading icon to prepare a PDF, the app will list all the pages of the document in its interface and you can apply copy protection to individual pages or to all of them at once.

Click Start Now after selecting the pages and the software will save a copy of the file to your destination folder.

Even if the program is not perfect, it will be useful to prevent users from copying parts of a document or at least make it more difficult for them to do so.

There you go, these are two fine methods of protecting your PDF files from unauthorized access. Of course, there are numerous other options available, both free and paid.
