Web is an ocean of videos & there are numerous video sites. We all love watching videos. YouTube has gained popularity from a wide range of audiences – from kids who love to watch cartoon shows to adults who browse through TV shows they miss. It uses Adobe Flash Video technology to display its videos. It now has three main video formats: standard, high and 720p HD. However, it does not usually show download links for its videos since they want videos to be viewed through their website. Third-party programs (browser plugins, software applications, and websites) now offer a way to download YouTube videos.
Here are the top 3 ways to download videos for free.
