No, it's actually quite efficient. I just did a test and using
imagemagick's convert command to turn 11 scanned jpegs (total size
712kb) into a single pdf document gave a final size of 684kb.
Generally the two sizes will be about the same.
The advantages of the pdf (to my mind) are that it keeps the files in
sequence, turns a bunch of jpegs into a single download, and it makes
printing very easy. I originally used individual jpegs when i was
distributing scans of lecture overheads, but printing was tricky.
With a pdf, printing is a doddle.
Using the cli to sane, then imagemagick to threshold and filter the
images, and then again to generate the pdf document (all in a script)
made the generation process very efficient.
