In their own words
PDiff
PDiff is desktop software for comparing PDF documents and identifying differences in layout, formatting and page breaks. It displays PDFs side by side, synchronizes extracted text with the pages and highlights deviations in both views. Reviewers can navigate differences, mark changes accepted, hide less relevant changes and add comments. Filtering and review tools include exclusion areas, page ranges, text-flow and table tools, replacement rules, comments and OK checkmarks.
PDiff can compare PDFs with DOC/DOCX, RTF, TXT, XLS and other common formats, converting non-PDF files through their native applications. Outputs include tabular, annotated and side-by-side PDFs, XML, CSV, PDiff project files and CLI return codes. PDiff Professional adds GUI batch processing and command-line operation. CSci Computer Science GmbH describes uses including quality assurance, regulatory compliance, contract and legal review, pharmaceutical packaging and technical documents. The software supports Unicode, including Chinese, Japanese, Korean, Arabic and Hebrew. The maker says processing is local and documents are not transferred over the internet. Business customers can request a free full-functionality trial; pricing for editions is on request.
