UKAAF partners with PDF Association to influence onward development of the PDF Universal Accessibility standard

The alliance will help ensure that PDF technology developments continue to promote and improve easy readability/conversion of documents for visually-impaired users

London – November 29th, 2019The UK Association for Accessible Formats has today announced a formal partnership with the PDF Association, which promotes international standards for PDF document technology.

The alliance will enable UKAAF to have a more direct influence over future developments of the PDF Universal Accessibility standard (PDF/UA) – the informal name for ISO 14289. This is the international standard for accessible PDF technology – a technical specification intended for developers implementing PDF writing and processing software. It provides definitive requirements for accessibility in PDF documents and applications.

Commenting on the significance of the partnership, Richard West, Chair of UKAAF, said, “Being in partnership with the PDF Association enables UKAAF to be involved with future developments of the standard. It is crucial that material produced by those using PDF technology allows improved accessibility and usability.”

For its part, the PDF Association is able to influence international organisations and individual members, increasing their appreciation of the importance of developing future technology that better meets the needs of blind and partially-sighted people. An example would be to more easily use a .pdf file and re-format it for partially sighted examination candidates, and help improve readability and use on single and multi-line braille displays.

The PDF Association, headquartered in Berlin, Germany, has an international membership spanning businesses, non-profit organisations, government agencies and individual consultants from over 35 countries. Representatives include developers of PDF solutions; companies that work with PDF in document management and enterprise content management; interested individuals; and users who want to advance their implementation of PDF technology in their organisations.


UKAAF (the UK Association for Accessible Formats) is the industry association improving the social inclusion of blind and partially sighted people, and others with a print-reading impairment, by promoting better availability and quality of accessible formats. It sets standards and promotes best practice for quality accessible information based on user needs, and helps organisations better meet the needs of people who struggle to read standard printed materials.

UKAAF’s members include individuals, transcribers, service providers, educators, researchers, print services, publishers and end users. More at and on Twitter @UKAAF.
