PDF Hacks

[ #28063 ]

I have a handful of PDFs I want to combine into a single PDF. I remember trying to solve this problem on OS X a few years ago, and found no (obvious) native tools to use, and a very few open source tools that could do the job. Eventually, I found some little open source applet written in RealBasic that worked the one time I needed it; I don't remember what it was, and probably never used it again.

Of course, that's totally lame. A real solution would involve something from CPAN and a couple of lines of Perl. For example, something like this:

#!/usr/bin/perl -w
 
use strict;
use PDF::Reuse;
 
my $output = shift(@ARGV);
 
prFile($output);
prDoc({file => $_}) foreach (@ARGV);
prEnd;

PDF::Reuse has lots of other features, including picking and choosing which pages of a PDF to reuse and merge. But for joining a whole mess of PDFs together into a single file, this works wonderfully.

Thanks, Lars!

  • OK, it's not really a "native" solution either, but if you've got a tex distribution (say "teTeX") kicking around on the system there's a similarly nice solution via:

    texexec --pdfarrange --result all.pdf file*.pdf

    (or even using ghostscript

    gs -q -sPAPERSIZE=a4 -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output.pdf
      *.pdf

    )

    If you want more control over importing certain pages you can use the pdfpages package in latex; just run the following file (call it all.tex or whatever) through latex:

    \documentc
  • and thank you for posting this, very useful
  • Cool. Here's another solution

    % cpan install CAM::PDF
    % appendpdf.pl file1.pdf file2.pdf out.pdf

    or almost equivalently:

    use CAM::PDF;
    my $doc1 = CAM::PDF->new(shift);
    my $doc2 = CAM::PDF->new(shift);
    $doc1->appendPDF($doc2);
    $doc1->cleanoutput(shift);

    -- Chris

    P.S. I'm the author of CAM::PDF
  • Very cool, I was just thinking about this the other day. I found a different solution (I had the originals and combined into one document first).
