DiffPDF

DiffPDF can contrast 2 PDF files. It provides 3 contrast settings: Words, Characters, and Appearance. By default the comparison is of words on each pair of pages, however comparing character by character is additionally supported (e.g., for logographic languages). As well as there's also support for comparing the web pages by appearance (for example, if a diagram is altered or if a paragraph is reformatted, or a font changed). It is likewise possible to contrast certain web pages or web page varieties. For instance, if there are 2 variations of a PDF data, one with web pages 1-12 and the various other with pages 1-13 as a result of an extra page having been included as web page 4, they can be compared by defining 2 page ranges, 1-12 for the very first and 1-3, 5-13 for the second. This will make DiffPDF compare web pages in both (1, 1), (2, 2), (3, 3), (4, 5), (5, 6), and so on, to (12, 13).
