Why would someone want to split or merge PDF files? That's a question that needs to be addressed before we take a closer look at one of the programs that enables you to do just that. Merging PDF files can be useful if you have multiple pdf documents that you want to join together. An example would be all pdf files that you have received during a college class throughout the year. Advantages are that you only need to manage a single pdf document instead of multiple ones, which is better to keep an eye on the file and to make sure you do not accidentally delete one of the documents. This may also be useful for collectors of comic books or other documents that are released in pdf format.
Splitting makes sense as well. Maybe only part of a pdf document is of relevance.You can split the parts of the documents that you need to keep from the rest to reduce the overall size of the document or access the contents that you need faster.
The Open-Source tool PDF SPlit and Merge has already been mentioned before in the split and merge pdf files article at Ghacks. Adolix Split Merge PDF is another free software that can be used to split and merge PDF files.
The software program uses a tabbed interface that provides access to a split and a merge tab. One PDF file can be added to the split tab which contains options to split the pdf file into files of x pages each or by selecting page ranges.
The merge tab looks pretty much alike with the difference that multiple pdf files can be added to it which are then merged in order.
Adolix Split and Merge can split and merge password protected pdf files. It is compatible to most Microsoft Windows operating systems and was tested on Windows XP Service Pack 3.
Update: A free and pro version of Split & Merge PDF is now available. The free version of the program is limited to 5 documents when it comes to merging, and 50 pages when it comes to splitting.
