DiffPDF is a small, simple, easy to use application specially designed to help you compare two PDF files. It offers three comparison modes: Words, Characters, and Appearance.
By default the comparison is of the text on each pair of pages, but comparing the appearance of pages is also supported (for example, if a diagram is changed or if a paragraph is reformatted). It is also possible to compare particular pages or page ranges.
What's New in This Release: [ read full changelog ]
· Can now have comparisons exclude text that's outside user-specified margins. This feature was sponsored by a company that prefers to remain anonymous
· Save As can now save images as well as PDFs
· Minor bug fixes and improvements
· Command line help (--help) will no longer work on Windows. This is to avoid a spurious console window appearing. I've put the output in the online help though
· Improved dock window handling so that docks can now be stacked on top of each other (useful for small screens)
