Arduo PDF Merger

Arduo PDF Merger is a straightforward software solution with a pretty self-explanatory name - it allows you to join documents with the PDF format. But it can also split files.
The app is wrapped in a clean and intuitive interface. Importing PDFs into the file list can be done with the help of the file browser ('drag and drop' is not supported).
So, you can select the pre-processing option between splitting PDF pages and none, as well as the action to take, between merging all documents into a new PDF, or exporting all the items to a folder.
The file queue shows the name, size and date of addition for each item. All you have to do is specify the output directory and filename, in order to proceed with the splitting or merging procedure. Arduo PDF Merger also creates a log file which is stored in the same location as the output PDFs.
The PDF processing program finishes a job briefly while using a moderate amount of CPU and system memory. It did not cause the operating system to freeze, crash or pop up error dialogs during our evaluation. On the downside, you cannot make Arduo PDF Merger open the output directory when the task is done, or preview documents in a built-in viewer. Nevertheless, inexperienced users can seamlessly find their way around the app, thanks to its intuitive layout and overall simplicity.
