I am looking for a program that splits and joins PDFs.

By this, I mean:

  • (split) I can choose the first x pages of a PDF and have it output separate PDF files.

  • (join) I can choose (up to 15) PDF files and have it output a single PDF.

I need it to:

  • run on Windows 7 and OSX Snow Leopard (10.6.8) (I don't care if the programs are different ones)
  • do the above
  • be free

This tool is free:


  • free (GPLv2), although the pre-compiled versions require a donation be made
  • open source
  • uses Java for cross platform goodness
  • split functionality - page by page, n pages at a time, split by size, by bookmarks
  • merge functionality - select a set of PDF files and merge them

It's predecessor was quite competent at merging documents.

I use PDFTK, which does precisely what you want - splitting and joining pdf files for free. I use it to extract sections from papers etc or book off etc. Split into individual pages then join the ones I need. https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/ There's a windows installer and command line support for osx and Linux (with very simple scripts like pdftk burst to split and pdftk *.pdf cat output.pdf to join all the pdf files in a directory (that I recall).
