Free Open Source Software

We are no longer maintaining or developing our open source software. The comparepdf tool has been superceded by our far superior commercial DiffPDFc tool, and the diffpdf application has been superceded by the faster and superior commercial DiffPDF.

  1. Alt_Key, a GUI application and library for calculating keyboard accelerators for menu option texts and dialog labels.
  2. comparepdf, a command line tool for comparing PDF files, either textually or by their appearance.
  3. diffpdf, a GUI application for comparing PDF files page by page, either textually or by their appearance.
  4. Easy Play, a GUI application for playing music—it is simple to use and remembers the current track in every playlist, so it is easy to go from playlist to playlist from where you left off.
  5. ViewPDF a GUI application for viewing PDF files that clearly indicates annotations and possible mistakes (such as spelling errors).
