Compare PDF and Office documents with ease using the .NET merge/diff library, specifically designed for this purpose.

One of the key features of this library is its ability to identify differences in both content and font styles. It also allows users to accept or reject changes when comparing Word files and compare up to three Word files. Furthermore, it provides the ability to export merged Word files to a resulting file with the native 'Track Changes' feature enabled. The library also offers the option to compare documents programmatically on the server-side and show differences through a web diff view UI. Moreover, developers can load documents/send the result output from/to streams and save a summary list of all changes in the output file.
The UI that comes with the library is mobile-ready and works across all popular platforms. End-users can view, navigate, and manipulate compared documents from any modern browser, without having to install any software or plugins. The UI offers a list of all differences found, quickly navigate between differences with the click of a button, search for, select and copy text to the clipboard right from the browser, etc. Also, they can export merged Word documents to an output file, scroll document pages or turn them with a button click, and preview/navigate document pages with thumbnails.
The GroupDocs.Comparison for .NET library is deployable with just a single DLL, as it does not require any 3rd-party dependencies. Additionally, it comes with a 30-day fully-functional trial for users to try before making a final purchase decision.
