PDFs at EPA

Making PDFs accessible is part of EPA's compliance with Section 508 of the Rehabilitation Act (Intranet) and it is required for all PDFs posted on EPA.gov.

PDF is a widely used format for presenting documents electronically that looks exactly like the printed originals.   PDFs are not as easy to use as text formats (e.g.; HTML and electronic documents) when using accessibility tools.

PDFs have to go through a process to make them accessible for use on the Web.  PDFs are tagged so that screen readers will be able to recognize the content and read it aloud.  Conversion of Word and other word processing documents to PDF goes more smoothly if the original document has been created to be more accessible from the beginning.   See: How to Create a Web-Ready PDF
