> correctly done, since ghfaxviewer cannot display the new image.

TIFF supports a wide variety of image types and some viewers can only deal with
a subset of the image types.

You probably want

  convert file.tif -resample 200x100 resampled_file.tif

Post the output of

  tiffinfo file.tif
  tiffinfo resampled_file.tif

so wee can determine how resampled_file.tif differs from file.tif.
