PDF Documents and Accessibility
Portable Document Format (PDF) is an electronic le format developed by Adobe Systems
Inc. PDF is one of the most popular le formats used on the Internet. e free Adobe Reader
soware -- available for Microso Windows, Apple Macintosh, and UNIX -- allows a PDF
documents visual integrity to hold true regardless of the computer used to view it.
Because PDF is used for such wide-ranging documents as product manuals, nancial and legal documents,
government related forms, and educational materials, it is critically important that people using screen
readers have proper access to this format. PDF is an electronic format, giving it an advantage over paper
documents because PDF documents can be accessed via synthetic speech or refreshable Braille.
Unfortunately, PDF and screen readers do not always interact as users would like. e main barrier to
accessibility is that PDF documents are not always designed by their authors to be compatible with screen
readers. ese issues, caused by lack of planning for accessibility, mirror Internet accessibility issues that
occur when a Web designer fails to follow the accessibility guidelines of the World Wide Web Consortiums
Web Accessibility Initiative. Adobe has developed a number of tools and resources to make it easier for
authors to create accessible PDF documents; these are available at http://www.adobe.com/accessibility.
Characteristics of an accessible PDF document
All accessible PDF documents have the following ve characteristics:
A logical structure and reading order
For screen readers to read a PDF document eectively, the document must have an underlying
logical structure and reading order. is logical structure and reading order use behind-the-
scenes elements called tags, which a PDF author adds to the document. Tags dene the intended
reading order of the content on each page. Screen readers rely on these tags to present text in a
way that makes sense when someone is hearing the text read out loud. e tags allow a screen
reader to interpret page elements such as headings, sidebars, tables, and multi-column text.
