Alternative Text

Also known as: Alt Text, Alt Attribute

Text associated with an image that serves the same purpose and conveys the same essential information as the image. Alternative text is a fundamental web accessibility requirement specified in WCAG, enabling screen reader users to understand image content. Standards for writing effective alt text emphasize naming objects, describing relevant details, and conveying the image's purpose in context. Research connects alt text practices to broader discussions about visual description and assessment descriptors in privacy tools.
