At a glance
- When to use it
- Before publishing a report, handout or client deliverable.
- What you get
- Page-level findings, manual review prompts, and CSV or JSON exports.
- What to check yourself
- Reading order, image descriptions and the accuracy of tags require human review. This tool does not certify conformance.
How checks work
This is a preflight review, not a WCAG or PDF/UA certification. A detected tag or title does not prove that it is correct.
Files are limited to 20 MB each, 10 per batch and 100 MB total. Inspection covers up to 200 pages per PDF and 600 per batch. Very large text pages are capped at 100,000 characters and 2,000,000 per document. Partial results are labelled.
How checks workCommon questions
Do my PDFs leave my device?
No. File parsing, extracted text and comparison run in your browser. Exported reports may contain filenames and document titles; choose carefully where you share them.
Does a clean result prove accessibility?
No. These checks help you triage work. Reading order, image meaning, tables, forms and assistive-technology behavior still need review.
Can you repair scanned PDFs or missing tags?
This release checks documents and extracts existing text. It does not perform OCR, add tags or repair the original PDF. Use a suitable authoring or remediation tool, then check the exported file again.
