What format should we use to get best compression while splitting pdf to tiff

using (var scodecs = new RasterCodecs())
{
    string multiPageFileName = $@"{currentPath}\Split Pdf\test.pdf"; //add file path here
    CodecsImageInfo info = scodecs.GetInformation(multiPageFileName, true);
    scodecs.Options.Load.SuperCompressed = true;
    //scodecs.Options.Tiff.Save.qua

    string outputDir = $@"{currentPath}\Split Pdf\"; //add output location here

    for (int pageNumber = 1; pageNumber <= info.TotalPages; pageNumber++)
    {
        // Load the next image in the loop 
        RasterImage simage = scodecs.Load(multiPageFileName, 0, CodecsLoadByteOrder.BgrOrGray, pageNumber, pageNumber);

        // Save the page to a separate file 
        string pageFileName = Path.Combine(outputDir, "Page_" + pageNumber + ".tif");
        //scodecs.Save(simage, pageFileName, RasterImageFormat.TifLzw, 0);
        //scodecs.Save(simage, pageFileName, RasterImageFormat.Ccitt, 0);
        scodecs.Save(simage, pageFileName, RasterImageFormat.CcittGroup4, 0);
        simage.Dispose();
    }
}
