As its name clearly suggests, Free YouTube Video Downloader is a software tool that you can use to download videos from YouTube. Thanks to the program's design, it is extremely simple and easy to use for everyone. However, the program's functionality is very limited compared with other YouTube video downloaders. This tool allows you to download both a full video from YouTube and its audio stream only. However, the program does not include any video or audio conversion functionality, which is a common feature of many YouTube downloaders. Besides, Free YouTube Video Downloader offers a very simple user interface, though its visual design could be widely improved.
The program allows you to paste the URL of the video you want to download, and then asks you to press either the "Download Video" or the "Download Audio Only" button. The program's website states that it also supports drag-and-drop for adding the YouTube URL, though I could not successfully make this work after several attempts. Finally, you can select the output folder and the file name. Whether you are downloading a video or just its audio stream, you can always choose your preferred video and audio quality from those available in the YouTube file.
Another important feature this program lacks is true batch download. The tool offers you a "Download more..." button, though it merely runs another instance of the program for you to repeat the whole process. In conclusion, it might be worth trying this tool, as long as your needs go no further than downloading a video from YouTube or its audio stream. Otherwise, I would recommend you to look for a more advanced tool.
