Global Standard for PDF Accessibility – PDF/UA

• Defines the necessary features and functions a PDF must include to meet technical accessibility requirements and ensure it is accessible to all users
• In 2012, ISO approved and published the initial version of PDF/UA
• Current version: ISO 14289-1:2014-12

Benefits of PDF/UA

Complementary to WCAG

Bridges the gap between the PDF format and the global accessibility requirements outlined in the WCAG (Web Content Accessibility Guidelines) of W3C.

Clear Technical Requirements

Clearly defined and thoroughly documented standards provide essential guidance for developers, implementers, service providers, and procurement professionals.

Guaranteed Compatibility

Ensures that software, hardware, and digital documents can interact seamlessly, provided they adhere to the standard.

Foundation for Machine Checks

The Matterhorn Protocol defines 108 machine-verifiable success criteria, providing a reliable foundation for validating the accessibility of PDF documents.

Enhanced User Experience

PDF/UA-compliant documents offer an optimal user experience for individuals with disabilities and those using mobile devices.

Complete Coverage of the PDF Format

Extends the principles of WCAG to the PDF format, establishing specific rules for ensuring PDF accessibility.

Content Optimized for Mobile and Reuse

Future-proof content presentation with rich semantics, machine readability, and advanced adaptability options like mobile view.

Product and Company Independence

As an independent global standard, PDF/UA provides consistent checking results and reliable requirements, helping end-users make informed software choices.

Globally Recognized and Implemented

Since its introduction in 2012, PDF/UA has become an integral part of the digital accessibility and PDF landscape, referenced in various legislation worldwide.

Focus on Technical Accessibility

While WCAG addresses content and layout accessibility, PDF/UA zeroes in on the technical aspects of making PDFs accessible.

Equal Access for All

PDF/UA ensures that documents are usable, readable, and accessible to all users, regardless of any disabilities.
