How to optimize Word?

Open the site: Word . Drag and drop Word files to optimize and compress them online. Or just use a code sample in C#. Install Aspose.Words for .NET. Add a library reference (import the library) to your C# project. Open the source Word file in C#. Compress Word without losing quality. Call the Document.Cleanup() method. The resulting code may vary depending on the output file format. Get the compressed result as a Word file.

Why compress Word files in C#?
