Frequently Asked Questions
1Is alt text generated automatically?
Yes. AI analyzes each image and generates descriptive alt text. You can review and edit before saving.
2Why is alt text important for PDFs?
Screen readers read alt text to describe images to visually impaired users. Without it, images are invisible to those users.
3Does it work with charts and diagrams?
Yes. AI describes charts, diagrams, photos, and logos. Complex visuals may benefit from manual review and refinement of the generated text.
4Is this required for WCAG compliance?
Yes. WCAG 2.1 Level A requires all meaningful images to have text alternatives. This tool helps meet that requirement efficiently.
