GroupDocs.Editor is a .NET class library (DLL), that is designed to allow users to load their documents of different format, open them for editing, edit, and save the edited version to some format, which may be the exactly same as input, or may differ. The most basic thing is that GroupDocs.Editor is GUI-less, it has no GUI, but only a public API, so it should be used within end-user environment, but not as the standalone application. Despite GroupDocs.Editor can be used anywhere, where .NET Framework is installed, it is intended to be used in web applications. Main and most common GroupDocs.Editor usage scenario implies that GroupDocs.Editor is used in a web-application and is located on the server-side. Server-based code invokes GroupDocs.Editor methods, passes input documents and different parameters, and obtains results, that are transmitted to the client-side into the WYSIWYG HTML-editor, like CKEditor or TinyMCE. When user has edited the document in the browser and is sending back the edited content to the server, server-based code again invokes GroupDocs.Editor, passes edited content and obtains edited document in desired format.
