Make a PDF Accessible using Adobe Acrobat Pro

You can use Acrobat to make PDFs meet the common accessibility standards, such as Web Content Accessibility Guidelines (WCAG) 2.0 and PDF/UA (Universal Access, or ISO 14289). Acrobat provides the following accessibility tools:

Prepare for accessibility: A predefined action automates many tasks, checks accessibility, and provides instructions for items that require manual fixes. Quickly find and fix problem areas.
Accessibility check: It verifies whether the document conforms to accessibility standards, such as PDF/UA and WCAG 2.0.
Accessibility report: It summarizes the findings of the accessibility check. It contains links to tools and documentation that assist in fixing problems.
Reading options: It includes settings for the available reading options.
Reading order: You can use the Reading Order tool to examine the structure, reading order, and contents of a PDF.
Save as accessible text: It allows you to read the saved text file in a word-processing application. It also enables you to emulate the end-user experience of readers who use a braille printer to read the document.
