The following code uses LEADTOOLS .NET classes to convert any supported input document (such as PDF) to image-based DOCX.

The code uses the Leadtools.Codecs.RasterCodecs class to load the input file as raster image pages, the uses the Leadtools.Document.Writer.DocumentWriter class to create a DOCX document and add all the pages as images.

NOTE: To convert to document-based instead of image-based DOCX, use the Leadtools.Document.Converter.DocumentConverter class.

Code:

static void PdfToImageDocx(string pdfFileName, string docxFileName)
{
   RasterCodecs codecs = new RasterCodecs();
   // load all PDF pages as images
   RasterImage pagesImage = codecs.Load(pdfFileName, 0, CodecsLoadByteOrder.BgrOrGray, 1, -1);
   codecs.Options.RasterizeDocument.Load.Resolution = 300;
   DocumentWriter docWriter = new DocumentWriter();
   // Begin a new DocX document 
   docWriter.BeginDocument(docxFileName, DocumentFormat.Docx);
   // Add the pages 
   for (int i = 1; i <= pagesImage.PageCount; i++)
   {
      pagesImage.Page = i; // loop through the images from input PDF
      DocumentWriterRasterPage pageR = new DocumentWriterRasterPage();
      pageR.Image = pagesImage.Clone(); // copy the current image page into the new Docx page
      docWriter.AddPage(pageR);
      if (pageR.Image != null)
         pageR.Image.Dispose();
   }
   // Finalize document to disk 
   docWriter.EndDocument();
   pagesImage.Dispose();
}
