How checks work
Compares normalized extracted text, ignoring repeated whitespace. Similar text may be paired as a changed page; review the suggested pairings. It does not compare images, layout, annotations or the correctness of reading order.
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.
