Standards - PDFs

ISO 14289-1, better known as PDF/UA (Portable Document Format, Universal Accessibility), is aimed at everyone involved in creating a PDF. It is based on the PDF standard ISO 32000-1 (also known as Adobe PDF 1.7) and directly references that. It sets minimum requirements that make sure documents are compliant with devices that support people with disabilities. PDF/UA files require the information on their pages to be tagged, and it also allows users to create structure trees out of tags so that assistive programmes know in which order to read information.

The Matterhorn Protocol and Well Tagged PDF both provide open access guidance on compliance with PDF/UA.

The following are some helpful training resources on accessible PDFs:
