Convert PDF to DOC in C#

            //Create a PDF document and load sample PDF.
            PdfDocument doc = new PdfDocument();
            doc.LoadFromFile("test.pdf");

            //Use SaveToFile method and set conversion target parameter as FileFormat.DOC.
            doc.SaveToFile("PDFtoDoc.doc", FileFormat.DOC);

Convert PDF to images in C#

            //Create a PDF document and load sample PDF.
            PdfDocument doc = new PdfDocument();
            doc.LoadFromFile("sample.pdf");

            Image bmp = doc.SaveAsImage(0);
            Image emf = doc.SaveAsImage(0, Spire.Pdf.Graphics.PdfImageType.Metafile);
            Image zoomImg = new Bitmap((int)(emf.Size.Width * 2), (int)(emf.Size.Height * 2));
            using (Graphics g = Graphics.FromImage(zoomImg))
            {
                g.ScaleTransform(2.0f, 2.0f);
                g.DrawImage(emf, new Rectangle(new Point(0, 0), emf.Size), new Rectangle(new Point(0, 0), emf.Size), GraphicsUnit.Pixel);
            }
            //Save as BMP
            bmp.Save("convertToBmp.bmp", ImageFormat.Bmp);
            System.Diagnostics.Process.Start("convertToBmp.bmp");

            //Save as EMF
            emf.Save("convertToEmf.png", ImageFormat.Png);
            System.Diagnostics.Process.Start("convertToEmf.png");

            //SAVE as ZoomImg
            zoomImg.Save("convertToZoom.png", ImageFormat.Png);
            System.Diagnostics.Process.Start("convertToZoom.png");
