PDF/UA is the ISO family of standards for universally accessible PDF, defining requirements that make PDF content more reliably interpretable by assistive technology.
What this means
PDF/UA focuses on the internal semantics and structure of a PDF—such as tagged content, logical relationships, language, and accessible representations—rather than only how the page looks visually.
PDF/UA-1
ISO 14289-1 is the original PDF/UA standard and remains an existing standard.
PDF/UA-2
ISO 14289-2:2024 defines PDF/UA-2 for PDF 2.0.
Relationship to WCAG
PDF/UA is PDF-specific; WCAG is technology-neutral accessibility guidance and is referenced by many policies and regulations.
