using GdPictureDocumentConverter converter = new GdPictureDocumentConverter();


converter.HtmlPageHeight = 842;
converter.HtmlPageWidth = 1191;
converter.HtmlPageMarginTop = 10;
converter.HtmlPageMarginBottom = 10;
converter.HtmlPageMarginLeft = 10;
converter.HtmlPageMarginRight = 10;


using Stream inputStream = File.OpenRead(@"input.html");
using MemoryStream outputStream = new MemoryStream();


GdPictureStatus status = converter.ConvertToPDF(inputStream, GdPicture14.DocumentFormat.DocumentFormatHTML, outputStream, PdfConformance.PDF1_5);
if (status != GdPictureStatus.OK)
{
    throw new Exception(status.ToString());
}


outputStream.Position = 0;
status = converter.LoadFromStream(outputStream, GdPicture14.DocumentFormat.DocumentFormatPDF);
if (status != GdPictureStatus.OK)
{
    throw new Exception(status.ToString());
}


status = converter.SaveAsDOCX("output.docx");
if (status != GdPictureStatus.OK)
{
    throw new Exception(status.ToString());
}


status = converter.CloseDocument();
if (status != GdPictureStatus.OK && status != GdPictureStatus.Aborted)
{
    throw new Exception(status.ToString());
