PDF which i have used is attached document (3).pdf using Pdfcompare version 1.1.33 & PDFbox 2.0.11, i have two questions what is the limit for the pages that can compare? what is limit for PDF size?

There are no fixed limits. The only limit, that can happen is, that memory is running out. Pdf rendering can be very memory intensive. I try to cope with several strategies, as explained in the readme under "CompareResults with Overflow". Maybe you can monitor your memory consumption (e.g. using JVisualVM), while doing the compare and see what you find.
