PDF Accessibility Checker (PAC)

PAC24 is a great tool for testing for PDF/UA (PDF Universal Accessibility) and WCAG requirements. It also has additional quality checks. Though, the quality checks are not a standard, they do help minimize other accessibility errors. PAC24 is only available on Windows. However, there is a web version, also known as, AxesCheck, that MAC users can utilize.

AxesCheck checks for all the things that PAC24 checks for, however, it does not have the advanced features of being able to show the report in detail and show exactly where those errors are at on the PDF. This may make the creating accessible PDFs process a little longer.
