The new version PDiff 1.7.9420 has been released. The latest release of the text-based PDF comparison includes the following new features as a preview of PDiff 2.0:

  • New Toolbar Button “Automated Guess for Replacements”
  • Speedup due to optimized internal data structures
  • Comments and OK checkmarks are preserved after recomputation of the extracted text, e.g. after replacements or definition of exclusion areas
  • Autodetect function for the exclusion of page headers/footers (in the context menu “Rectangular Exclusions” of the PDF A/B preview widgets)

PDiff shows you quickly and safely all text differences between two PDF documents - as a comparison of the two PDFs and with markings of the deviations. So you can check intended revisions quickly and find unintended changes at first glance.

Applications of PDiff Professional are among others: pharmaceutical packaging and medical leaflets, important business documents, legal documents and contracts, technical manuals, financial reports, manuscripts, book texts as well as price lists and catalogs.

PDiff is available as 64-bit version for Windows and Mac OS X. Both versions are based on the proven Adobe® PDF Library. Business customers can request a free trial at
