A useful first check
Know what this can tell you.
It reads titles, language settings, tags and text. A missing setting can point to work; a setting that exists can still be wrong.
Continue with a human review
Reading order, correct tags, image descriptions, links, forms, contrast and text recognition accuracy are not checked. This is not a full audit or WCAG / PDF/UA certification.
Use a dedicated validator such as PAC alongside inspection with assistive technology.
