# What is EPUB Accessibility 1.1?

EPUB Accessibility 1.1 is the W3C Recommendation, published in October 2024, that defines when an EPUB is accessible and how to say so. It requires discovery metadata, WCAG 2 conformance and EPUB-specific features such as page navigation where a print edition exists.

## Why it matters when you convert a PDF to EPUB

Stores, libraries and the European Accessibility Act look for its conformance statement (dcterms:conformsTo) and the schema.org accessibility metadata it asks for. A converted PDF can be a good starting point, but only a publication that really meets the requirements should claim conformance.

The specification lists valid conformance strings such as "EPUB Accessibility 1.1 - WCAG 2.2 Level AA" and also asks for information about who evaluated the publication.

How EpubCC handles it: the engine writes no conformance statement and no accessibility metadata. What it contributes is structure: headings, reading order, language, a table of contents and linked notes, which is the part of accessibility that a PDF most often lacks.
