You can create alternative text (Alt text) for shapes, pictures, charts, SmartArt graphics, or other objects in your Microsoft 365 documents. Alt text helps people with visual disabilities understand pictures and other graphical content. When someone using a screen reader comes across a picture in a document, they will hear the alt text describing the picture; without alt text, they will only know they've reached a picture without knowing what the picture shows.

Use the procedures in this article to learn how to add alt text to a shape, picture, chart, SmartArt graphic, or other graphical objects.

To learn how to write alt text, go to Everything you need to know to write effective alt text.
