Pixel tolerance (0–32)

Result / Mode

Text additions/deletions and rendered pixel differences are separate checks. Layout, font rendering or scale can change pixels without changing meaning. Scanned PDFs receive visual comparison; empty text does not prove identical contents. Attachments, signatures and hidden objects are not certified. Reports include private document text.

Two PDFs up to 30 MB each, 20 pages, 2 MB extracted text, bounded text comparison and 40 MP total rendering. Rendered previews use at most 96 DPI, 2048 px per edge and 2 MP per page. Password-protected files are blocked.

Reports can contain private text or headers. Review before sharing.
