Adobe Acrobat offers helpful tools and support resources for creating accessible PDF files.
The Make Accessible Action feature in Adobe Acrobat can guide you step by step through creating and verifying an accessible PDF.
Meet PDF accessibility standards
Run an accessibility check to ensure your PDF conforms to the latest Web Content Accessibility Guidelines (WCAG) 2.0 and PDF/UA standards. Get a report of any problems so you can fix them.
Assign headings with the Reading Order tool to help viewers read your content in the correct order when they’re using screen readers.
Tag page elements and set alternative text for images so screen readers can announce image-based content in a tagged PDF.
