PDF Analyzer’s accessibility tag checker
A browser-based tool checks a PDF’s accessibility tags and flags structural problems that can make it harder to use with assistive technology.
- For
- PDF authors and accessibility reviewers
- Worth noticing
- It distinguishes machine-detectable structural issues from reading order, image-description quality, and contrast, which still need human review.
Field notes
The page lists checks for missing document language or title, image descriptions, skipped heading levels, broken table and list structures, and untagged text or images. It also says some questions are outside automated judgment: reading order, whether an image description is useful, and color contrast require human review. For a fuller PDF/UA check, it points readers to PAC and recommends trying the document with a screen reader.
