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).

Making sure that PDFs are accessible to everyone, including those using assistive technologies like screen readers, refreshable braille displays, screen magnifiers, etc., can be a daunting technical process.

Although web accessibility is most commonly thought of when talking about digital accessibility, document accessibility also plays an important role. Document formats such as Word, PowerPoint, Excel, ePub, and most commonly PDF, are quite common and are usually linked within web pages or sent via email. As such, it’s important to make sure that those documents are accessible as well.
