I've been looking everywhere (i.e. lots of Google searching) for pdfconcat, which supposedly is very good at merging PDF files together.
Anyone know where I can get this?
I am the author of pdfconcat. The offical source code download site of pdfconcat is http://pts-mini-gpl.googlecode.com/svn/trunk/pdfconcat/ . Example command-line for cancatenation of
pdfconcat is now a bit out of date, for example it cannot read PDFs with cross-reference streams or object streams. Since these would be complicated to implement (i.e. it would blow up the source code of pdfconcat by a factor of 10 or more), I don't think they will be implemented in pdfconcat.
As of now I recommend qpdf instead of pdfconcat for PDF concatenation. qpdf can generate small output files (if you use the command-line flags
As seen in other answers, you may also try pdftk (also available as an Ubuntu package) instead of pdfconcat for PDF concatenation. I tried pdftk now, and it didn't generate too large output files for me. If you get a very large file size with pdftk (i.e. much larger than the sum of the input sizes), send me your input PDFs (because I'm interested in what's going on). Example command-line with pdftk:
For Unix systems there is the
Please note that none of the concatenation methods above preserve all hyperlinks in the document (especially hyperlinks in a non-first input file). Please do adequate testing if your concatenation method preserves all the interactive PDF features you care about.
Are you sure it's pdf concat? Maybe you may try pdftk, which provides exactly the functionality, you describe.
