One Linux command line tool for jpg->pdf would be ImageMagick's convert
   convert anyfile.jpg anyfile.pdf
No filesize cap (that I'm aware of), but can't say whether or not it's
"better" with respect to your other problems.
And it's probably one-to-one with respect to "multiple pages",
but then pdfjam
   pdfjam pagenum*.pdf --outfile allpages.pdf
will definitely do that.
And check out both programs' manpages for numerous (and I do mean
numerous) other -switches.
