TubeDownload is a powerful tool to download videos from YouTube and many other similar video-sharing websites. The program is capable of downloading a configurable number of videos simultaneously. Moreover, this tool can convert the downloaded videos into 16 popular video formats, or extract their audio streams and save them as audio files. All of that in a simple and easy way.
Thanks to its intuitive user interface which includes big auto-descriptive controls -, this program can perfectly be used even by inexpert users with basic computing skills. You can add video URLs for downloading in one of two modes: normal and quick. Normal mode allows you to paste the video's URL, select the video definition, and the target format and codec. The program supports a large number of popular audio and video file formats, such as AVI, MOV, MP4, 3GP, MKV, DVD, VCD, as well as MP2, MP3, ACC, AC3, Ogg, WAV, and WMA. But besides that, TubeDownload also includes multiple presets for several popular devices, such as Apple, Samsung, Nokia, Motorola and Sony, just to mention some. Anyway, whichever output format you select, you can always customize its internal parameters - like the video resolution, its frame rate and the audio sample rate - to fulfill your specific needs.
TubeDownload claims to provide very fast download speeds, as compared to any previous downloader you might have been using. Besides, you can pause/start every download job individually, or you can also pause/start them all with a single click. Also, the program installs an always-on-top icon on your desktop that is said to allow you to drag a video's URL over it to start the download job immediately. However, I could never manage this feature to work.
In a few words, TubeDownload is a handy app that provides you with all the tools you need to get your favorite YouTube videos downloaded and ready to be played either on your PC or on your portable devices. As a disadvantage, I will mention that the program's trial version allows you to test it only for 10 days before you make a decision.
