Simple Unrar

Simple Unrar is an application that lets you extract any compressed file in RAR format. In fact, you can extract almost any file that's compressed in RAR 5.0 format or lower, even those with a password (although you obviously need the password for this).

Simple Unrar is an interesting free alternative to the official Winrar app for Android. It lets you extract all your compressed files directly from your Android device. This application is also really lightweight, taking up less than one megabyte on your device's memory.
