Merge Join and Combine Multiple PDF Files into One

Merge Join and Combine Multiple PDF Files into One has a long name but it perfectly describes its purpose – the tool lets you merge PDF files.
The interface of the application is based on a standard window where you can import PDF files by using the file browser only, since the 'drag and drop' method is not supported.
The file queue shows the source path of each item. Once you establish the target folder and output filename, you can immediately start the merging procedure with the simple click of a button.
Additionally, you can specify the base source folder, make the tool search in subfolders and insert a page separator between joined PDF files, move items up and down in the list, as well as remove an item from the file queue or clear the entire thing.
The PDF processing program barely leaves a mark on the computer's resources, as it uses a low amount of CPU and system memory. It has a good response time, quickly finishes a task and manages to keep the original document quality regarding images, graphics and the text layout.
We have not come across any issues throughout our testing; Merge Join and Combine Multiple PDF Files into One did not freeze, crash or pop up error dialogs. However, the tool comes with limited features. For example, you cannot preview documents or minimize the app to the system tray. But it can be seamlessly handled by inexperienced users, thanks to its intuitive layout and overall simplicity.
