It’s a well known problem. You have two PDF documents and you want to merge both into one. For e.g. you want to bring your application and your personal data sheet together. This short an easy tutorial shows you how to do this on console or with an graphical helper.
First option: commando line
Of course there is a way to use the console to do this. The command line tool pdfunite is an easy way to do this. You can use APT on Ubuntu or Debian to easily install pdfunite:
user@client:~$ sudo apt-get update user@client:~$ sudo apt-get install poppler-utils
pdfunite is part of the poppler-utils package, which basically means that when you install poppler-utils you will also get the desired pdfunite. After the installation is finished, you can just go ahead and merge some PDF files!
To merge start merging, you have to enter the command pdfunite followed by the PDFs you want to merge. The last PDF file in the command line represents the output PDF:
user@client:~$ pdfunite source1.pdf source2.pdf merged_output.pdf
The number of PDFs you can merge is infinite so this line can be extended like this to merge 4 PDFs for e.g.:
user@client:~$ pdfunite source1.pdf source2.pdf source3.pdf source4.pdf merged_output.pdf
Keep in mind that the source files have to be in the same directory where the command pdfunite is executed. If your PDF files are stored in different places, you have to enter the relative or absolute path, for e.g.:
user@client:~$ $HOME/pdfs/source1.pdf $HOME/pdfs/source2.pdf $HOME/Downloads/source3.pdf /mnt/externalhdd/source4.pdf merged_output.pdf
And that’s it. All the magic is done 🙂
Second option: Using a GUI
There are several GUIs which are doing all the work for you but one of those GUIs is (for me) the real shining star: PDFsam. The main reason for this is that PDFsam is capable of doing a lot of more things than just merging: Split, Rotate, Extract, Split bookmarks and many more. PDFsam is written in Java and (of course) available in most Linux distributions. For Ubuntu / Debian you can easily install PDFsam like this:
user@client:~$ sudo apt-get update user@client:~$ sudo apt-get install pdfsam
After PDFsam is successfully installed, you can start PDFsam through your start menu or by entering the command pdfsam in a terminal window.
With an click on the button Merge the merge window is going to pop up. The rest is almost self-explaining. Click on the button Add choose the source PDFs from your drive you want to merge, go down to the Destination file, click on Browse and select a place + filename for the merged destination PDF. Click on Run and that’s it.
As you can see, merging PDFs under Linux is super easy. If you want a graphical toolset which offers more possibilities than just merging, go with PDFsam. If you just want to merge PDFs on a simple and easy way or if you are just a fan of the command line, go with pdfunite. However, it doesn’t matter which program you use. There are both fast, reliable and easy 🙂
