Downloading videos from YouTube and other similar sites is the in thing. Although the web offers us all the comforts we need to not worry about storage space, the truth is that when a video is online we have no control over it: it can be removed without prior notice and we won't be able to see it if we lose our connection.

Therefore, there are dozens of online services and apps to download them, one of which is the well-known KeepVid and its Pro desktop version that we're offering you after having tried out its webapp and APK for Android smartphones and tablets.

How to use it to download music and videos?

If you've used its online version before, or you've simply tried other similar apps, you'll have no trouble using it. You've only got to add the URL to the search box and click on the button that appears in the browser. Just choose the file quality and format, and that's it, in a few seconds you'll have video in the folder chosen on your hard drive.

Download videos and convert their format.

However, this isn't any old YouTube downloader as it comes along with a series of functions and features that makes it much more complete than its competitors:

• Download videos and music from over 10,000 websites.
• Download channels and playlists in batches.
• Format converter: convert them to MP3 and MP4.
• Edit covers and audio tags.
• Record online music and video.
• Turbo mode.
• Download subtitles.
• Extension for Firefox, Chrome and Internet Explorer.

Here you'll find a link to the trial version, but it has somewhat limitations. However, you can get hold of the full Pro version to remove them.

What services and sites is it compatible with?

Well, if there's an online version that allows me to download videos without paying, why should I go for this paid version? Basically, because it's compatible with thousands of webs, whilst the free version only supports 28 of them. These are some of the sites you can download videos from YouTube, Facebook, Vimeo, Dailymotion, BBC, NBC, Yahoo, ESPN, SoundCloud, Vevo, MTV and so on. Can you download videos from adult sites?
