How to View Word Documents as PDFs in Java

The following steps outline how to easily render a Word document to a PDF using a few lines of Java code:

  • Utilize the Viewer class to load the Word document.
  • Set up the default PDF View Options.
  • Use the view method to convert the loaded Word document to a PDF.

Here is an example of the Java code that can be used to perform this conversion:

This is what the above code produces as a result:

Creating Secure PDF with Disabled Printing Option from Word Document in Java

Here, you will find the answers to the following questions in just a few lines of code:

  1. How to convert a Word Document into a password-protected PDF in Java?
  2. How to create a PDF with disabled printing options in Java?

These steps will guide you on how to convert a Word document into a protected PDF with limited permissions in Java:

  • Set up the security settings using the Security class.
    • Specify the document opening password to restrict access to the document.
    • Define the permission password to restrict PDF printing, modification, and data extraction.
    • Set the permissions to allow or deny permissions.
  • Set the PDF View Options and add the security settings to it.
  • Load the Word (DOC/DOCX) document using the Viewer class.
  • Use the view method to render the loaded Word document as a password-protected PDF with limited permissions.

The following Java code demonstrates how to convert a Word document into a protected PDF with no printing permissions:

PDF Secured with Password

When the PDF is opened, it will now prompt the user to enter a password before accessing the document.

Enter Password for Secured PDF

The output PDF will have limited permissions as set during the conversion process. As a result, the user will not be able to print the PDF due to the disabled printing option.
