    Remove form fields

    On this page

    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;
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
    };
     
    viewer.View(viewOptions);
}

    The following image demonstrates the result:
