If you invest in one or both or these tool sets, you will likely find much less need to visit the 508 PDF Help Center. These tools automate many PDF accessibility remediation tasks.

  • PAC 1.3 (scroll to the bottom of the page): The predecessor of PAC 2, PAC 1.3 has a different style of screen-reader-emulator that I prefer, especially when working with tables.
  • CommonLook PDF Validator from NetCentric Technologies checks a PDF against Section 508, WCAG 2.0 AA, PDF/UA, and HHS (U.S. Health and Human Services) standards, as well as checking other factors such as broken links.
  • pdfGoHTML from Callas Software provides a screen-reader-emulator view somewhat similar to the viewer in PAC 2, with some additional features. pdfGoHTML installs as an Acrobat Pro plug in, making it very convenient to use while working in Acrobat Pro.
  • VIP PDF Reader from the Swiss National Association of and for the Blind is another great tool for visually checking the reading order and certain other human-inspection-needed PDF accessibility factors.
  • Colour Contrast Analyser from The Paciello Group is a simple tool for checking luminosity contrast, for example to help determine the legibility of colored text on a shaded background.
