You can drag a ZIP or RAR file (or even multiple ZIP/RAR files) onto the DropZip icon and they will be magically unzipped into a folder with the same name as each ZIP or RAR file, for example.

For example: drag your Zip file softpedia.zip from My Documents onto the icon. Look in My Documents, there will be a new folder called Softepdia.

DropZip also has another feature if you drop a folder (it must be one folder on its own) then that folder will be converted to a ZIP file (note the folder won't be deleted).

DropZip is not designed to be a replacement for your normal ZIP or RAR programs; instead, it is designed for convenience when you need to quickly unzip or unrar something.
