With the popularization and maturity of smartphone camera technology, the video file has more and more formats and sizes. Especially for short video shooters, there are two main problems they have to face: 1) the file format does not meet the requirements of the video platform and needs to be converted to upload; 2) the file size exceeds the limit and cannot be uploaded to the video platform.

YouTube Downloader Pro (full name: Jerry YouTube Downloader Pro) is a universal video downloader developed by Jerry Software from China. Don't be misled by its name, which is just the name it used when it was originally designed to download YouTube videos. Today, it is powerful enough to help you search, download, and convert videos from YouTube and hundreds of other popular video websites, and up to 500% faster than normal file downloaders.

Due to the characteristics of digitized information, copyright proprietors have to use another unique technology to strengthen the copyright protection of their digital contents (including software, audio and video, electronic documents, electronic books, hardware), this technology is DRM (short for Digital Rights Management). However, the use of this technology for protecting digital content brings users great inconvenience on a variety of devices - you have to play your video/audio files on the specified devices or players due to the DRM copyright protection measure.

If you are same to me, like to download all kinds of video/audio resources from the Internet, and then store them to mobile devices, like MP4, PSP, iPhone/iPod or cellphone, just in order to kill some time when you have nothing to do. If so, a multiple file formats conversion application is indispensable, which can ensure that your video/audio files can get around to be played in different equipment.
