Learn about accessibility metadata, ARIA roles, and structural enhancements available when exporting Adobe InDesign documents to EPUB.
InDesign includes accessibility features that improve screen reader compatibility and assistive technology support for exported EPUB documents. These enhancements let you define accessibility metadata, apply ARIA roles, and ensure proper structural tagging so EPUB content is more usable for a wider range of readers and assistive technologies.
To access this feature, select File > Export and set a File name and select EPUB (Fixed Layout) in the Save as type option. In the EPUB - Fixed Layout Export Options dialog box, select Metadata and then the Accessibility tab.

More Accessibility enhancements
InDesign supports accessible EPUB export through structured tables, figures, semantic tagging, and ARIA roles.
- Tables include proper headers and data cells, including column headers, for assistive technologies.
- Figures can be exported with captions using figure and figcaption tags, allowing screen readers to announce captions. Live Captions are also supported.
- Drop caps are styled with a special technique (pseudo-element) to preserve text recognition for screen readers.
- SVGs can be exported with image tags, retaining vector quality and accessibility metadata such as alt text and decorative roles.
- Context breaks can be mapped to tags like hr to indicate section separation. These can be created using empty paragraphs, text, or inline images and styled through paragraph settings.
- ARIA roles can be applied at the object or frame level and through paragraph or character styles to help screen readers identify content types such as notes, chapters, or credits.
- Glossaries can be structured using definition list semantics, improving navigation in reflowable EPUBs.
