PDF documents are readable by screen readers if they are text and if all non-text content has “alt tags” or alternative descriptions. But they may still be hard to navigate, especially if they are lengthy or complex. Consider an organizational constitution and bylaws with many sections and subsections, or a college textbook. But what about graphs and charts? Are they readable?
If you convert your accessible Word document into a PDF, your PDF document will be accessible. Otherwise, you have to tag your PDF document, using Acrobat Professional, to make it accessible. It’s a tedious, difficult process. Start with an accessible Word document! For details on making an accessible PDF, watch this video and read this page.
