Create and verify PDF accessibility

Acrobat tools make it easy to create accessible PDFs and check the accessibility of existing PDFs. You can create PDFs to meet common accessibility standards, such as Web Content Accessibility Guidelines (WCAG) 2.0 and PDF/UA (Universal Access, or ISO 14289). The simple, guided workflow lets you do the following:

Make PDFs accessible: A predefined action automates many tasks, checks accessibility, and provides instructions for items that require manual fixes. Quickly find and fix problem areas.

Check accessibility: The Full Check/Accessibility Check tool verifies whether the document conforms to accessibility standards, such as PDF/UA and WCAG 2.2.

Report accessibility status: The Accessibility Report summarizes the findings of the accessibility check. It contains links to tools and documentation that assist in fixing problems.

With axesCheck you can quickly and easily check PDF files for accessibility. axesCheck is a web-based version of the PDF Accessibility Checker PAC it will check PDF files to see if they meet the machine-verifiable requirements of PDF/UA (according to the Matterhorn Protocol) and WCAG (A & AA). Additional checks are recommended that only a human can perform - for example, whether the sequence of elements is correct, the tags correspond to the visually recognizable semantics, or alternative texts reflect the meaning of an image.
