If you have both an iPhone and a Samsung Galaxy S3, or you own an iPad while your wife has a Nexus 7, you may be looking for a way to transfer several common video files onto both devices for viewing on the go. Due that both iOS and Android devices support specific video formats only, the video conversion process is inevitable.

There are numerous video converter software tools on the Internet (by a simple Google search) that can be used to convert video files to play on iPhone, iPad, iPod touch as well as Android phones and tablets. Here I’d like to share a totally free video converter application named HandBrake. HandBrake is quite easy to use in that it provides optimized presets for iPod, iPhone, iPad, Apple TV, and Android for your choice. There’s also a universal preset for all iOS and Android devices. Besides, you are allowed to crop the video area, customize video and audio parameters, import subtitles, etc.

Below is the main interface of HandBrake for Windows:

Using HandBrake, you can easily import video files from your computer, choose a desired profile and start to convert on the fly.

When you get the output video files, you can start to transfer them to your iOS or Android device following the guides below:
