Accessible PDFs and Documents


Accessibility laws apply to all forms of online content, including PDFs and documents.

You have a role in ensuring that everyone has equal access to information regardless of the format.

By making PDFs and documents accessible to people with disabilities, you’re making all digital content easier for everyone to access, understand and use.


  • PDFs and documents are only accessible if you make them accessible. They are not accessible by default.
  • PDF is intended for a printed page and not for screens. 
  • Do not use a PDF to present digital content that could be a web page.
  • HTML is always the most accessible, mobile-friendly, easy-to-update, and user-friendly format.
  • Making a non-accessible PDF into an accessible PDF, a process known as remediation is time-consuming and may be technically challenging.
  • Many websites have a print to PDF feature
