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.
