This report aims to highlight the accessibility of the documents found on four different organisations’ websites. The purpose of this is to highlight the accessibility issues found in PDFs hosted on the internet and what these issues mean for users with disabilities. This report is useful for both document creators and managers who wish to better understand the components of an accessible PDF and how to assess their own document creation processes.

The analysis in this report was conducted using the freely available PDF Accessibility Checker. Throughout the analysis it was clear that many PDFs had fundamental flaws with respect to accessibility, even though visually they looked fine. Some issues can be traced back to the PDF generator used and the document creation process, while others are a result of incorrect document set up. Of the documents assessed 36% were deemed to be wholly inaccessible due to missing internal data in the PDFs. While some organisations’ websites performed better than others, all have significant room for improvement in their provision of accessible PDFs.
