Introduction
Alternative text (alt text) provides written descriptions of images, shapes, charts, and other visual elements in a document. Screen readers announce alt text so that users who are blind or with low vision can understand the purpose and content of the visuals. Alt text is essential for meeting digital accessibility standards and for ensuring documents are perceivable under WCAG's POUR principles.
From Visual to Verbal: Translating Images into Meaning
Translating images into meaning is to describe not just what is visible, but what is significant, by capturing the information a viewer needs in order to understand the content without relying on sight. Therefore, alt text should be meaningful and concise. Best practices include keeping it brief while communicating the purpose of the visual element, being factual, and being objective.
Focus on what the image shows, why it is included, and any essential data that it coveys.
Avoid redundancy in previously presented information and avoid including "image/picture/photo of" in the description because the screen reader will already announce that information.
When is alt text needed?
Add alt text to photos, images, illustrations, charts, graphs, icons, and the like.
Do not add alt text to design elements that do not convey meaning (such as image borders); mark as decorative in such cases.
