Creating Accessible Documents in Acrobat Pro

It is always best if possible to start with an accessible source document (e.g., in Microsoft Word) and export to an accessible PDF.  This way, if the document is edited later, the document's accessibility features will still be intact and when the document is exported again to PDF the accessibility features will again be passed to the PDF.

However, if the original source document is not available, accessibility features can be added to the PDF using Adobe Acrobat Pro DC.

WebAIM's tutorial on  makes for an excellent accompaniment these video tutorial.
