Hi Prasanth,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

I'm afraid, your requested feature of comparing two PDF files using Aspose.Pdf for .NET is not supported at the moment. We have already logged a new feature request as PDFNEWNET-31260 in our issue tracking system. However, this issue may not be support in near future. You'll be notified via this forum thread regarding any updates against this feature.

Sorry for the inconvenience,
