Universal Accessibility – PDF/UA

Delivery of digital content in accessible way is based on the idea that everybody should be able to equally  use the information contained in documents. It applies to people with disabilities who require any form of assistive technology (screen readers, speech recognition etc.) to properly interpret document content.

Legal institutions all over the world have the aim to make whole web accessible and pdf is an important part of the institutional and government web sites. As an answer to this effort the ISO 14289-1 standard (PDF/UA) was born in 2012. It addresses all practical as well as legal needs required by WCAG 2.0, 508 Compliance and other regulations.

This standard allows pdf to join the effort and became the only possible way for static documents to be fully accepted. A lot of agencies, archives, libraries etc. nowadays accept only accessible documents.

The US Access Board says in V. Major Issues, A. Electronic content:

The central principle underlying the accessibility requirement for public-facing content is the notion that federal agencies must ensure equal access to electronic information that they themselves directly make available to the general public by posting on a public fora. So, for example, if a federal agency posts a PDF version of a recent settlement agreement on its website as part of a press release, that document would need to comply with PDF/UA-1.

To have pdf file accessible, they need to comply with ISO 14289-1 which technically means to be properly tagged and also to meet requirements defined by The Matterhorn Protocol (

Demanding and expensive?

The requirements for general tagged files and for PDF/UA files are not complementary, but you can use our Autotag  feature to automatically generate tags in existing documents and then manually check and adjust documents. Our PDF/UA generator generates using our recognition algorithm directly PDF/UA files that pass accessibility checkers ( and ready to be published on WCAG 2.0 compatible websites.
