I convert tiff to g4 tiff with the following
tiffcp -L -c g4 -r 10000 infile1 [infile2...] outfile
This tool takes much less memory to convert. This is
from libtiff-3.5.5-2.
http://www.libtiff.org/ (part of the tifftools)
I have a version that I fixed some problems in c42pdf at
ftp://ftp.pdp8.net/software/c42pdf/
If somebody wants a windows binary I can try building a command line one
with cygwin, email me.
Command line I use
c42pdf -q -o outfile -p o --nostretch --noflip infile.tif
It also has a --pages flag to only convert some pages. This is done on
the fly to convert the tiff's on my site to pdf.
This doesn't create optimized PDF's so acrobat can't fetch them a page
at the time (for good or bad, frequently that delay on each page annoys me)
