       diffpdf - compare two PDF files textually or visually


       diffpdf [file1] [file2]


       This manual page very briefly documents the diffpdf command.  (Click the GUI's Help button
       or press F1 for more information.)

       DiffPDF is a GUI application used to compare two PDF files.
       By default the comparison is of the words on each pair of pages, but  comparing  character
       by character is also supported (e.g., for logographic languages). And there's also support
       for comparing the pages by appearance (for example, if  a  diagram  is  changed  or  if  a
       paragraph  is  reformatted,  or a font changed). It is also possible to compare particular
       pages or page ranges. For example, if there are two versions of a PDF file, one with pages
       1-12  and  the other with pages 1-13 because of an extra page having been added as page 4,
       they can be compared by specifying two page ranges, 1-12 for the first and 1-3,  5-13  for
       the  second. This will make DiffPDF compare pages in the pairs (1, 1), (2, 2), (3, 3), (4,
       5), (5, 6), and so on, to (12, 13).

       If the program is passed two PDF filenames on the  command  line  it  will  start  up  and
       compare  those  files in Text mode (or in Appearance mode if the filenames are preceded by
       -a or --appearance).
