Is there a painless way to combine/merge PDF files in Windows? I understand that pdftk will do it on Linux.

There are quite a few free options, as well as some good commercial ones:

Web-based (Free)

  • MergePDF. Merge up to 10 files. Max limit of 5MB/file.
  • PDF Hammer. Web-based PDF editor that supports merging of multiple files
  • Booklet Creater. Merges files to create a booklet. Rearranges pages to that you can print and fold to create a simple booklet.
  • BCL Premium PDF Merge Merge 2 PDF documents. Max 10MB/file. Limit of 20 merges/day

Desktop tools (free)

  • PDF Sam. Also known as "PDF Split & Merge". FOSS tool for splitting and merging PDFs. Windows & Mac. Console and GUI interfaces. On Windows its installer by default installs Ad-Aware Security Toolbar, sets Lavasoft SecureSearch as homepage, new tabs, and default search provider.
  • Swift PDF. Combing multiple images into a single PDF. Does not merge PDFs, but does merge, JPG, GIF, etc.
  • pdftk. FOSS power tool. Command line only. Windows, Mac, Linux, FreeBSD.

There are also a lot of commercial tools.

Just tried PDF Sam and the resulting PDF it generates is version 1.5 at minimum, when I needed version 1.4. In case you need that, on Windows you can use PDF Version Converter, available here: freeware-guide.com/dir/util/pdf.html –  Rahul Dec 10 '10 at 14:19
PDF Sam is not free and doesn't allow to do a thing until it's bought. Please, exclude it from the list. –  polkovnikov.ph Dec 5 at 20:32

Check sourceforge.net/projects/pdfcreator. When installing software is not an option, then combinepdf.cc is quite neat.

This little app I found with a Google search let me merge image files into a single PDF, which it didn't look like some of these options would. It's very limited, but it did the trick for me just now.

Also this program named pdfbinder proved to be useful. It has a simple commandline interface for input and uses the same engine as the PDF Split and Merge already mentioned.

You can use PDFill PDF Tools to perform lots of manipulations on your PDFs for free.

Use the "Merge PDF Files" button (button #1) in the screenshot below.

Try PDFsam, which comes for Windows, Mac OS X and Linux.

The basic version is free, I'm pretty sure that the basic version will meet your needs. You will need to have Java installed on your computer to run this program.

I verified that this works. Thanks. –  user1413 Sep 2 '09 at 13:36

I found the best for me: PDF Split and Merge

enter image description here

PDF Split and Merge tool is implemented using the PdfSharp library and is either GUI or command driven.It is useful for automated document creation.It allows bookmarks from the input pdfs to be imported and flexibly embedded in the destination document.

It just merges or splits PDF files, nothing else.

pdftk.exe is available for Windows as well. See here: http://www.accesspdf.com/pdftk/#packages and here: http://www.pdfhacks.com/pdftk/pdftk-1.41.exe.zip

Here is an example commandline for pdftk.exe. It merges all PDF files in the current directory into a combined one:

pdftk.exe *.pdf cat output combined.pdf

Another one:

\\myserver\c$\path\to\pdftk.exe ^
   c:\path\to\input1.pdf ^
   d:\path\to\input2.pdf ^
   cat ^
   output ^

Ghostscript can also combine multiple input PDFs (and PostScript files) into one output PDF:

gswin32c.exe ^
        -dBATCH ^
        -dNOPAUSE ^
        -sDEVICE=pdfwrite ^
        -sOutputFile=output.pdf ^
        [...more Ghostscript CLI options as needed...] ^
        input1.pdf ^
        input2.pdf ^
        input3.ps ^
        input4.eps ^

pdftk was already suggested in this answer - superuser.com/questions/34284/… –  ChrisF Jun 24 '10 at 13:01
I know. But user1413 seemed to have missed pdftk to be available on Windows as well. Therefor I emphasized that point by repeating it. –  Kurt Pfeifle Jun 24 '10 at 15:52

PDF Creator will do the trick -- you can print multiple documents to a single PDF. Relatively painless :)

I know that you can do this with Adobe Acrobat. I assume that you don't want to pay for this if it's the only use you have. Ghostscript, available on Linux and Windows, should be able to concatenate them, but it uses complicated command-line functions. You can use CutePDF, which has a free version, but I believe the Professional (paid) version is the only one that will concatenate.
