A screen reader will interpret an inaccessible PDF as an image, not text. This page will walk you through the process of creating accessible PDF documents. You can either start with a Word document and convert this document to PDF or you can make an existing PDF accessible. Please note that making an existing PDF accessible is more difficult and time-consuming than starting with the original Word document.PDF documents may be appropriate to use in your online course if the document is a form, historical document, or if the document has a complex layout. PDF documents can be created to be accessible, however, they are not as navigable with a screen reader as HTML and require Adobe Reader in order to view them.How to Create a PDF Starting with a Word DocumentStep 1: Create a Properly Formatted Word DocumentFormatting Checklist:Apply heading styles to your document. Headings are required for screen readers to be able to read the document.For more than one column of text, create a table with column or row headings.Apply the appropriate list style to bulleted and/or numbered lists.Provide alternative text for all images in your document.Insert active hyperlinks for all URLs in your document.Check correct formatting guidelines if you use equations.Use bold or italic text to display emphasis. (Please do not use underlined words. Underlined text on a web page indicates hyperlinks.)To ensure accessibility, please do not use colors to indicate meaning (e.g., colored text or highlighted table rows and columns).Step 2: Create a PDF File from your Properly Formatted Word DocumentVerify that Adobe Acrobat Professional has the accessibility setting turned on.Once Adobe Acrobat Pro is open, click on the Edit tab at the top of the program.Click PreferencesClick Accessibility under Categories on the left, be sure the first two items are checked for tab order and enable assistive technology support.Click OK.Create a PDF from your MS Word document.Save your MS Word document to your computer.Open Adobe Acrobat Pro.Click Create PDF from File from the Create Adobe PDF box.Select the MS Word file from your computer.

These tags are not displayed in the document, but they are used by screen readers to understand the structure of the document. Tagging documents used in online courses allows people with visual disabilities to access materials as easily as their fellow classmates.
