You can try the following code to convert PDF pages to images:
using (RasterCodecs codecs = new RasterCodecs())
{
   codecs.Options.Load.AllPages = true;
   RasterImage image = codecs.Load(inputFile); //String path to input file
   for (int i = 0; i < image.PageCount; i++)
     {
       image.Page = i + 1;
       string filename = string.Format("image_{0}.png", i + 1);
       codecs.Save(image, filename, RasterImageFormat.Png, 0, image.Page,
       image.Page, 1, CodecsSavePageMode.Overwrite);
     }
}

Hi,

You can use Spire.PDF to convert PDF to image easily. Check the following code:
PdfDocument doc = new PdfDocument();
doc.LoadFromFile("sample.pdf");

for (int i = 0; i < doc.Pages.Count; i++)
{
    System.Drawing.Image bmp = doc.SaveAsImage(i);
    string fileName = string.Format("Page-{0}.png", i + 1);
    bmp.Save(fileName, System.Drawing.Imaging.ImageFormat.Png);
}

The article which I shared in that you can convert pdf to jpg, jpeg or png also. But i don't think so you can convert pdf to image using itextsharp because itextsharp is used just for pdf conversion. Thanks
