ArcConvert is a small application that allows you to convert archives between several formats, including ZIP, 7ZIP, CAB, TAR, BZA and ARJ.

The software doesn't require any installation. Since it is portable, you can place ArcConvert on an external device and directly run the executable file on any computer. Also, your Windows registry entries will remain intact.

The user interface of the program consists of a standard window in which you have limited options. You can open an archive by using the file browser or the "drag and drop" method.

So, you can check the archived file, set the priority level (normal, idle, high or realtime), specify the output format, input a password (if the file is encrypted), update the check and initiate the conversion process.

Once the task is completed, you receive a popup message. But you can also view the original and new size of the archive.

As you can see, ArcConvert is pretty minimalistic when it comes to its functionality. Also, it doesn't include a help file (it doesn't need one since it is extremely simple to use). On the other hand, it takes up a low amount of system resources and didn't freeze, crash or pop up any errors during our test.

So, if you are looking for a simple tool that can seamlessly convert compressed files, then we strongly recommend ArcConvert.
