Add accessibility tags to PDF files to make sure that people who use screen readers and other assistive technologies can read and navigate a document with Tables of Contents, hyperlinks, bookmarks, alt text, and so on. Accessibility tags also make it possible to read the information on different devices, such as large type displays, personal digital assistants (PDAs), and mobile phones. In Microsoft 365 for Windows, Microsoft 365 for Mac, and Office for the web, you can add tags automatically when you save a file in PDF format.
