Questions about ALT attributes

Common questions about alternative text, accessibility, and visual semantics.

Do all images need descriptive alt text?
No. Decorative images can use an empty alt attribute, but informative images should have a useful description.

Not necessarily. It should be clear, concise, and contextual.
Does the tool replace human review?
No. It detects technical patterns, but the real usefulness of alt text requires editorial judgment.
