Portable PDF Merge Tool

Portable PDF Merge Tool is a software with a pretty self-explanatory title. It allows you to merge multiple PDF files.
Since this is a portable application, PDF Merge Tool does not need to be installed.
That means you can place the tool on an external device (like a USB flash drive) and directly run the executable file on any computer.
More importantly, there will be no changes made to your Windows registry items.
This is one of the simplest programs you'll ever have to deal with. The interface is a small window in which you can import PDF documents by using either the file browser or the "drag and drop" method.
So, all you have to do is arrange your PDFs in the list and initiate the task by pressing the "Merge" button (you can set the output destination and name). Plus, you can remove an item from the list. And that's about it!
The program quickly finishes a task while taking up a low-to-moderate amount of system resources. Also, the output file is automatically opened after it has been created. No errors have popped up during our tests and Portable PDF Merge Tool didn't freeze or crash.
To sum things up, Portable PDF Merge Tool is straightforward, simple to use and low demanding for joining two or more PDF files and we strongly recommend it to all users.
