Image alt text is a short written description of an image on a website or app. It helps explain what the image shows, especially if the picture does not load or if someone uses a screen reader.
People use image alt text to make content easier to understand and more accessible. It is also helpful for search engines, since it gives them more context about the image.
Meaning & Usage
Alt text is usually added behind the scenes in the image code. Most people do not see it unless the image is missing or they use assistive technology. Good alt text is simple, clear, and describes the image’s main point.
Examples
If a photo shows a woman holding a laptop, the alt text might say: “A woman working on a laptop at a desk.” If the image is a logo, the alt text might be the brand name.
Why is image alt text important?
It makes websites more accessible for people who cannot see images clearly and helps search engines understand the image.
Should alt text be long?
No. It should be short and useful, usually just enough to describe the image clearly.
Do all images need alt text?
Most important images should have it. Decorative images may not need a description if they do not add meaning.
