This seems like a roundabout way to get from point A to point B, since Acrobat can use JPG compression to reduce file sizes of images depending on what you instruct it to do in the job options. The balancing act here is to achieve an acceptable resolution "and" the smallest file size. Only the user will know when that balance has been achieved. But, that said, here's how I would get there. I saved a 12 x 18 grayscale image as a tiff (18.7 mb). On Windows, and using Acrobat 6.0.1 with the highest quality job options, I simply right clicked the tiff file and used the Convert to PDF command. The PDF file size at 300 dpi resolution was 371 kb, a file size reduction of over 95%. It could be possible to reduce the file size even more by fooling around with the compression settings in the Distiller job options. Once you achieve the results you desire, then send a copy of your job options (which is a text file you can provide a unique name for) to your service provider. Give them instructions on what to do. The process is sort of like going to the doctor. Not every professional is going to have the right answer without some homework and guidance on your part. P.S. You should upgrade to Acrobat 6.X and instruct your service provider to do the same, if they haven't. Hope this helps you get where you want to go.

These are fundamentally different formats and, for relatively simple images at least, bitmaps are always going to generate much bigger files. Again, I'm no expert so I won't try to explain the differences between bitmaps and vectors but your solution *might* be a bitmap to vector conversion program - I use CorelTRACE but I'm sure there are others to choose from. The results vary greatly depending on the type of image you are working on but if your originals are line drawings you may find that the results are suitable. Hope this helps a bit.

Most are output to Acrobat from several CAD apps. Some of these are scanned hand-drawn vellums, tho. We scan the 11x17 B-size ourselves on an old Ricoh IS410 bed scanner inputting CFM-Twain at 300 dpi in scanmode halftone set to error diffusion. The resulting pdf files (single sheets) are coming out at 2 and 3 meg. Unacceptable with the number of files we have to store. Anybody know how to do this and get smaller files with a decent image? Also we're having our larger hand-drawn vellums done by an outside repro house and they're doing a tiff scan import that's generating filesizes of 300k to 400k. I'm used to seeing 40k or 50k come from our CAD programs. What can I tell the repro house to help get their file sizes down?
