While it is getting easier every day to upload videos to social media, it may not look as trivial to download videos from social media.
Sure, you can always play with the source code of a post if you enjoy diving into the guts of web pages.
But there is a simpler way: DownloadTwitterVideo, a pretty cool online tool that helps you download videos from social media to your computer for free.
And, despite what the name of this tool suggests, in addition to Twitter, DownloadTwitterVideo also allows you to download videos from Facebook, Instagram, Vine, Tumblr, YouTube and DailyMotion.
Keep in mind though, that you can only download videos from public profiles.
