Toonel is a java application that helps you save your internet bandwidth by compressing the incoming and outgoing data. This is a great way to save bandwidth if you are on a limited bandwidth package. Since it is developed in java its platform independent and runs on Linux, Windows, Mac and also on some mobile devices.
Toonel uses a lossless compression by utilizing JZlib library which enables you compress the internet bandwidth as you receive or send them. The data incoming or outgoing goes through a tunnel where the compression is obtained. You just have to download the application and configure your computer or mobile device to use toonel as a proxy. Then it starts compressing your internet bandwidth.
