Ultra PDF Merger is a simple handy program for the Windows operating system that can perform that operation. The program is offered as a free download on the developer website. Please note that it is supplied as a rar file which needs to be unpacked with a compatible software (like 7-zip). The program itself requires the Microsoft .NET Framework 4.0. It can be run without installation.

You find options to add and remove individual pdf documents in the program interface. A click on the Add button opens a file browser that displays all pdf files of the selected folder. You can then add one or multiple documents stored in that folder to the program queue. Each document is listed with its file name and path in the interface.

The move up and down buttons can be used to rearrange the document order which can be handy if you want to arrange them by date, name, alphabet or another sort order.

The Merge Files button opens a save window where the location and name of the merged document needs to be selected.

All documents currently in the queue are then merged in the selected order and saved under the new file name. Please note that you may need to run the program with elevated privileges as you may otherwise receive an error message when trying to save the new document.

PDF Binder is an Open Source tool for the Windows operating system that can be used to merge PDF files effectively. PDF documents can be dragged and dropped into the program interface after installation and startup or by using the Add File button in the program interface.

The PDF files will be concatenated in the exact order that they are added to the program with the top entry the first to appear in the resulting document.

PDF Files that have been added to the software program can be removed from it and sorted by using the up and down arrows that become active after selecting a PDF from the list.

The Bind button will open a save file dialog window where the target filename for the PDF needs to be specified. The process takes a few seconds the most and will save the pdf file that contains all merged pdf documents into the selected directory.

PDF Binder is an easy to use application to merge PDF files. It is Open Source, compatible with many Microsoft Windows operating systems (tested on Windows 7 Professional) and requires the Microsoft .net Framework. The tool can be downloaded from the project’s homepage at Google Code.

These pdf editors usually contain the means to modify the pdf metadata but there are cases where other means of editing might be more comfortable or appropriate. One scenario might be the need to edit the pdf metadata using a computer without the appropriate pdf editor, another speed.

Splitting makes sense as well. Maybe only part of a pdf document is of relevance. Instead of keeping the complete pdf file a user could split the document and keep the important parts and delete the rest.

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.
