Accessibility features in PDFs
A document or application is accessible if people with disabilities, such as mobility impairments, blindness, and low
vision, can use it. Accessibility features in Acrobat DC, Acrobat Reader DC, and Adobe Portable Document Format
(PDF) enable people with disabilities to use PDF documents, with or without screen readers, screen magnifiers, and
braille printers.
Making PDFs accessible tends to benefit all users. For example, the document structure that enables a screen reader to
read a PDF out loud also enables a mobile device to reflow and display the document on a small screen. Similarly, the
preset tab order of an accessible PDF form helps all users, not just users with mobility impairments, fill the form more
easily.
Accessibility features in Acrobat DC and Acrobat Reader DC fall into two broad categories. There are features to make
the reading of PDF documents more accessible, and features to create accessible PDF documents. To create accessible
PDF documents, use Acrobat, not Reader.
