Oops, that's how to do the opposite thing: Convert PDF to image files
with various tweaks. Here's something more like what I intended:
convert *.jpg [output].pdf
Combining a large number of big images into one PDF file takes a lot of
resources and may even fail if your system is not very powerful. For
those cases, this little script will do the job:
for f in *.jpg;
do
convert "$f" "${f%.jpg}.pdf"
done
pdftk *.pdf cat output combined.pdf/
(Needs the pdftk "PDF toolkit", available in all the major Linux repos.)
