PDF Accessibility Checker
The PDF Accessibility Checker (PAC) provides a fast way to test the accessibility of PDF files. On one hand, it checks whether the PDF/UA standard is met. On the other hand, it offers a great preview feature that visually displays the document similar to the way a screen reader perceives it, making it easy to spot problems in both sequence and meaning of elements.
As it does not have an installer, you can simply extract it to a folder of your liking.
Launch PAC. To examine a PDF document, click on the
Select PDF File button.
Inspect the displayed results.
To ensure that the PDF's content is marked up correctly and the elements are ordered properly, open the
Screen Reader Preview and compare it with the original document.
