No doubt YouTube is the biggest online video library available at the moment. However, there are certain videos that you may want to download to your PC so that you can playback them offline later. If this is your case, you can use a tool like Wondershare Free YouTube Downloader, which helps you download videos from YouTube with ease.
Basically, you can download YouTube videos in two ways: you can copy a video's URL in your web browser and paste it into the program's interface using the "Paste URL" button, or you can use the add-on the program installs on all the major web browsers (Internet Explorer, Mozilla Firefox, and Google Chrome) to directly download YouTube videos with one click. Besides online videos download, the program offers you other extra functions, like on-screen video recording. The program also includes its own built-in Internet browser especially designed to open online video websites like YouTube, Vimeo, Dailymotion, Hulu, and others. However, its rendering engine seems to be based on Internet Explorer 7 which is pretty obsolete and causes certain problems when you try to open most of those websites. As an additional feature, the program also offers you its own media player, which allows you to enjoy your downloaded videos.
Even though this is supposed to be a free tool, it behaves more like a demo tool due to the number of limitations it presents. For example, you can download videos from YouTube exclusively, one video at a time, record on-screen videos only of up to 2 minutes, and you are not allowed to convert your downloaded videos into other formats (even though you are offered the option to do so!). Of course, you can get rid of all those limitations if you buy a license and register the program (in which case it migrates to a more advanced tool called Wondershare AllMyTube).
In a nutshell, Wondershare Free YouTube Downloader actually offers pretty less features than it pretends. Anyway, if you just need to download a few YouTube videos and their output format is not an important matter to you, I would still recommend you trying this tool, especially because of its ease of usage.
