If you want your document to be read but not edited, you can save it as a PDF file. When you do, the PDF will retain your formatting and often be a smaller file than the original document. Tagged PDF files make it easier for screen readers and other assistive technologies to determine a logical reading order and navigation for the file, as well as allowing for content reflow when using large type displays, personal digital assistants (PDAs), and mobile phones. This tagging can be done automatically when you save a file as PDF format.
You can send a PDF copy of your document directly from Word.
For information about saving documents as PDFs in other versions of Microsoft Word, go to Save as PDF.
