Converting PDF Byte Array to jpg image in c#

I am trying to convert PDF Byte Array to image in a project.Is there any way to convert pdf byte array to image without using any external libraries like Ghost script,PDFRasterizer.NET 3.0 etc

 using (FileStream file = File.OpenRead(@"D:\FileFolder\file.pdf")) // in file
{
      var bytes = new byte[file.Length];
      file.Read(bytes, 0, bytes.Length);

       byte[] pngBytes = bytes; // need to convert image type and assign
       using (var outFile = File.Create(@"D:\FileFolder\file.png")) // out file
       {
             outFile.Write(pngBytes, 0, pngBytes.Length);
       }}
