The freeware program PAC provides a fast way to test the accessibility of PDF files. PAC supports both experts as well as end users conducting accessibility evaluations.
The Matterhorn Protocol (PDF) is designed to foster adoption of PDF/UA by providing a set of 31 Checkpoints and 136 Failure Conditions that help software developers exchange detailed information on PDF/UA conformance and create software to make it easier for document authors to create fully accessible PDF files and forms.
PAC 2, the new PDF Accessibility Checker from Access for All, a Swiss non-profit organisation, is the first implementation of the Matterhorn Protocol.
PAC ist recommended by the World Wide Web Consortium (W3C): PDF Techniques for WCAG 2.0
