what the recommended dll for file compression,disassembly assemble of pdf tiff files

we are running a custom application for archiving purposes asp.net based with twain and api for core archiving app (third party)
with main functionality (scan using twain driver ) assemble scanned papers to one tiff file format and save the file (document)
we ran into issue as assembled document has a medium size for black/with 500kb  and large size for color documents (10-90)mb
which is unacceptable
target size is
(20-200 kb) for black and white documents (papers around 10 pages)
(200kb-2 mb) for colored documents relay on resolution and # of papers per documents
any suggestion for a good dll can be used to (disassemble,assemble)with a good acceptable size
hint:
current document count vs size is 52,000 document with total size 46 GB

If you are looking for a compression util then try 7-Zip  http://www.7-zip.org/download.html  Free to use.  That may compress the files but they'll be in zip format rather than tiff.  Which may not be what you want.

Also are you putting your TIFF files into PDF?  If so, why?  Why not keep them in TIFF?

Also from a rough look at your figures you are wanting to compress your TIFF files by up to a factor of 50x.  That is extreme and quite probably not doable.

Go back and have a look at your requirements.  Do you need the full quality of your present TIFF documents?  Could you save them with lower resolution and quality?  Do you actually need TIFF, would JPEG do the job instead of TIFF?  JPEG would give you vastly smaller file size at the cost of fidelity but do you need that fidelity?

HI

we are keeping the documents as tiff files.

the problem if we are combining 2 images into one tiff file,the new produced document has higher size that both of them together.

Thanks

How are you combining the two files together?
