Today, I heard from Mark Summerfield

Hi Steven,

I’ve just released DiffPDF 1.2.0.

There are small improvements in the user interface plus a tiny bug fix
of one setting that wasn’t saved/restored correctly.

I am hoping that this will be the last release for quite a while!

I’d be very grateful if you’d create a statically built Windows version:
your build for 1.1.5 is proving very popular!

Thanks:-)

So I compiled and released it in the first time, feel free to download it here

P.S. Change logs

DiffPDF is developed by Mark Summerfield, I just compiled it to windows 32 version.
DiffPDF depends on poppler, poppler-qt, Qt4 library.

DiffPDF can compare two PDF files. It offers two comparison modes: Text 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. 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).

It is open source(of course free software), want to try it on your windows XP/Windows 7, please download here.

With PDF Timestamp Signer, we can create Timestamp signature on a PDF without the need of Adobe Acrobat.
You can download it from here.
This version has some limited,

• It only support create visible signature, and put the signature on the left bottom corner(100, 100, 300, 200) of the first page.
• It use http://tss.pki.gva.es:8318/tsa as timestamp server
• It only supports PKCS12 certificate file.
• It run as windows 32 console application, so it has no windows, and only run in Dos command
