I assume that you're using the tiff2pdf tool.

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.
