Pick a PDF to run the checks.

The checker reads the tags, language, title, alt text, table headers, bookmarks, and text layer the file actually stores, and quotes what it saw for each check. It sits below full PDF/UA validators such as veraPDF or PAC: it cannot judge whether alt text describes its image, cannot read the TH Scope attribute, and does not measure contrast or reading order. Structure detail covers the first 200 pages; later pages are counted only. The manual checklist after the findings is the part that still needs you.
