PDF documents are not always accessible. Accessible PDF documents are often called “Tagged PDF” because they include “tags” that encode structural information required for accessibility.

To save Word document as tagged PDF document:

  1. Go to menu item: File
  2. Select Save As
  3. In the File name box, type a name for the PDF file
  4. In the Save as type list, select PDF (*.pdf)
  5. Select the Options button
  6. Ensure the Document structure tags for accessibility checkbox is checked
  7. Check the Create bookmark using: Headings checkbox, so that the headings you are using in the Word document will be available in the PDF document too
  8. Select OK
