This video only covers Word and PowerPoint. What about PDF documents?
To make PDF documents accessible, which includes adding alternative text descriptions for images, you need a copy of Adobe Acrobat Pro DC. Acrobat Pro DC is available by request through the ITS website opens a new window. If you do not have your own copy of Acrobat Pro DC or are unfamiliar with how to use it for making content accessible, contact the ATI Office for assistance.
See the Submitting your Documents for an Accessibility Review using Ally video below for additional guidance.
