Recognize that the tiff2pdf tool in many instances does no conversion of the image data. It merely exchanges the TIFF wrapper for a PDF wrapper. Therefore it is expected that the data size would not be much different. If you want to alter the data compression mechanism first I suggest that you use tiffcp before tiff2pdf. Thanks, Lee.
