Say there is a book that has been split into several PDFs. I want to do two things:

  1. Merge the PDFs and reduce the size of the resulting PDF.
  2. Fix the page numbering.

(1) can be done with pdftk or Ghostscript. For me, Ghostscript creates considerably smaller PDFs and is the only program (of the two) available on my PC.

Example:

gs -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -q -sOutputFile=output.pdf input_1.pdf input_2.pdf [...] input_n.pdf

Why is (2) a problem at all? Because different books start counting page numbers on different pages whereas your PDF reader starts counting at page 1 if you don't do anything. This can be fixed with an empty document, the package pdfpages, \setcounter, and \pagenumbering.

Example:

\documentclass{article}
\usepackage{pdfpages}
\usepackage{hyperref}
\begin{document}
\pagenumbering{Roman}
\setcounter{page}{4}
\includepdf[pages=-]{input_1_with_TOC.pdf}
\pagenumbering{arabic}
\includepdf[pages=-]{input_2.pdf}
\includepdf[pages=-]{input_3.pdf}
% ...
\end{document}

My problem is now: I want to fix the page numbering and create a small PDF but calling pdflatex and then Ghostscript creates a PDF that is considerably bigger than a PDF that has been merged with Ghostscript.

How do I create PDFs as small as with (1) while having (2)?

EDIT: Forgot to add hyperref to the LaTeX code.

  • Is TeX really the best tool for this job? There are PDF libraries for many scripted languages that could renumber pages May 1, 2013 at 21:04
  • If you are dealing with the pdf outputs only, there is no feasible way to modify the page numbers of the pagination. From the pdf's point of view they are just digit (or character!) sequences that happen to be positioned at some peculiar place of the page. May 1, 2013 at 21:04

    @HagenvonEitzen: There are the page numbers in the text ("on the paper") and there are the page numbers that are shown by your PDF reader. I want to change the latter. May 1, 2013 at 22:32
  • GhostScript likely reduces the size of the PDFs because it reduces the resolution of included bitmap images. Do you really want that? May 3, 2013 at 11:20

    @Martin Schröder: Yes, I want to reduce the resolution. Otherwise I would have used Ghostscript with -dPDFSETTINGS=/preprint or only pdfpages. May 3, 2013 at 14:25

  1. Merge with Ghostscript.
  2. Use pdfpages on the Ghostscript output like this:
\documentclass{article}
\usepackage{pdfpages}
\usepackage{hyperref}

\begin{document}
\pagenumbering{Roman}
\setcounter{page}{4}
\includepdf[pages={1-17}]{gs-output.pdf} % contains table of contents
\pagenumbering{arabic}
\includepdf[pages={18-}]{gs-output.pdf} % Rest of the book
\end{document}
