Alt text for different image types

All images in your text require an alt attribute. However, not all images require alt text or the same level of detail. Whether you need to add alt text and what the alt text contains depends on the type of image.

For information about adding alt text in different tools and platforms, refer to Alt text for different platforms.

tip

For help with determining what kind of image you have, please refer to the W3C Web Accessibility Initiative's Alt decision tree.
