You could try using the Document Comparer from Leadtools. They have a demo on their site here:

Try out GroupDocs.Comparison for .NET API. It is a back-end, UI-Independent API. Hence, it could be integrated in any of your .NET application either it is web based or desktop. Below code will serve the purpose:
//Source and target files to be compared
string source = @"source.pdf";
string target = @"target.pdf";
Comparer comparer = new Comparer();
//Compare two documents
ICompareResult result = comparer.Compare(source, target, new ComparisonSettings());
result.SaveDocument("output path", "output name");
You can also explore this open-source project https://github.com/groupdocs-comparison/GroupDocs.Comparison-for-.NET-MVC.

Take a look at iTextSharp - you can use that library as the basis for building a compare tool: http://sourceforge.net/projects/itextsharp/
