If there are multiple pages in a PDF file, multiple JPEG/JPG or PNG files will be generated using following code:
string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.jpg");
SavePageStream getPageStream = page => new FileStream(string.Format(outputFileTemplate, page), FileMode.Create);
using (Converter converter = new Converter("sample.pdf"))
{
    ImageConvertOptions options = new ImageConvertOptions
    {
        Format = ImageFileType.Jpeg
    };

    converter.Convert(getPageStream, options);
}
All it takes is a single DLL file that can be downloaded here https://downloads.groupdocs.com/conversion/net.
You can implement this API in any (new or existing) .NET project (web, console, desktop).

you have typed one is for adding details to pdf. read step1 and step2. in step 1 they are opening pdf file using spire.pdf. so pdfdocument.SaveAsImage is from the spire.pdf dll.
for example, after convertion I got one image with evalution warning (check the file uploaded)

Hi,

Check the reference.It's not Spire.Pdf..!!!

Again I am looping the Itext Sharp Code below :
Document document = new Document();
PdfWriter.GetInstance(document, new FileStream("Sample.pdf", FileMode.Create));
document.Open();
document.Add(new Paragraph("Hello World"));
PdfPTable table = new PdfPTable(3);
table.SpacingBefore = 30f;
table.SpacingAfter = 30f;
PdfPCell cell = new PdfPCell(new Phrase("Header spanning 3 columns"));
cell.Colspan = 3;
cell.HorizontalAlignment = 1;
table.AddCell(cell);
table.AddCell("Col 1 Row 1");
table.AddCell("Col 2 Row 1");
table.AddCell("Col 3 Row 1");
table.AddCell("Col 1 Row 2");
table.AddCell("Col 2 Row 2");
table.AddCell("Col 3 Row 2");
document.Add(table);
Image image = Image.GetInstance("1.PNG");
document.Add(image);
document.Close();
