PDF/UA and WCAG overlap but serve different roles: PDF/UA is a PDF-specific ISO standard, while WCAG is a technology-neutral set of accessibility success criteria.
What this means
Organizations often encounter both. Regulations may reference WCAG, while PDF/UA provides detailed PDF-specific requirements that help a PDF conform to an accessibility model that assistive technologies can interpret consistently.
Use WCAG to evaluate outcomes
WCAG defines testable accessibility success criteria across technologies.
Use PDF/UA for PDF semantics
PDF/UA specifies requirements for the internal structure of accessible PDF.
Treat them as complementary
A robust PDF accessibility program often considers both rather than choosing only one.
