How to Add and Edit Alt Text in PowerPoint Presentations

A few weeks ago I published a video about how to add alt text to pictures in Google Slides. That video was prompted by a friend's request for help. This morning a reader asked me about using alt text in PowerPoint. So I recorded the following short video to demonstrate how you can add alt text and edit alt text in PowerPoint. The video includes instructions for the browser version  of PowerPoint and for the desktop version of PowerPoint (thankfully, the two versions are getting more similar all the time).


Applications for Education
After I published my last video about alt text I had a few people ask what purpose it served. The purpose of alt text is to convey the purpose of an image in a presentation or online document. This is done to help students who use screen readers access the full content and purpose of the presentation.

For more information about the purpose of alt text and what alt text should entail, read How to Write Alt Text and Image Descriptions for the Visually Impaired published by the Perkins School for the Blind eLearning.
