Alt text is the written description of an image. It helps screen reader users understand what’s being shown.
What to include:
The image’s purpose
Important details
Keep it short and clear
Examples:
For a headshot: “Jane Doe, professor of biology, smiling.”
For a chart: “Bar chart showing enrollment increase from 2020 to 2023.”
For a decorative swirl: Leave alt text blank or mark it decorative.
You can add alt text in Word, PowerPoint, Adobe Acrobat, and most website tools. It’s one of the easiest ways to make your content more Accessible.
