If the output PDF file contains form fields, you can flatten them to reduce the file size.

To remove form fields, set the RemoveFormFields property to true.

The following code snippet shows how to flatten form fields in the file:

using GroupDocs.Viewer.Options;
using GroupDocs.Viewer.Domain.Documents.PostProcessing.Pdf.Optimization;
// ...

using (var viewer = new Viewer("sample.docx"))
    PdfViewOptions viewOptions = new PdfViewOptions();
    viewOptions.PdfOptimizationOptions = new PdfOptimizationOptions()
        RemoveFormFields = true
