ConcatPDF

Text documents are encountered in an abundance of domains of activities, and these can come under different formats. In this regard, PDF files managed to build quite the reputation because of their security options. As such, ConcatPDF comes as a handy tool you might need in order to merge multiple PDF documents, or split them.

Work on one or more PDF documents

Setup only keeps you busy for a little while, but you do need to make sure that .NET Framework is on your computer. You find multiple executables inside the deployment package, and this is because there’s no actual main menu to hold them all. By default, the application is meant to bundle multiple documents together into a larger one, while the other tools you find are extras.
The window you get to work with is wrapped around a classing windows frame, which mostly comprises of an upper toolbar, as well as a decent list in which all files you want to process are added. Needless to say that you can process more files at a time, but this changes the mode to merge, rather than split.

Some functions are launched through a command line interface

There are various details which can be configured before the target process is put in motion. Viewer options make it possible to set page layout and mode, as well as user interface and window handling. A password can be added to documents for enhanced security, while image and page settings adjust the visual style and page layout.
As mentioned, there are a bit more tools than merging. Note, however, that these must be used as command lines, because there are no interface options for easier management of functions. Even so, there are different switches to make the most out of the set of features.

In conclusion

Taking everything into consideration, we can state that ConcatPDF comes with good intentions, allowing you to perform quite the variety of operations on one or more PDF files. Sadly, they’re not all packed inside a single interface, making it rather difficult to work in command line instances for each type of option to apply or change.
