Using the application is as simple as copying the video's URL into a text field and clicking 'download'. In that moment, a pop-up will appear asking you to indicate the resolution in which you want to download and save the video, if there are multiple options.
So, if you are able to choose to watch a video in HD on its webpage (YouTube, for example), then you can choose to download it in HD. Additionally, you can create download queues, adding several files to be downloaded consecutively.
Free Video Download is a simple download tool that allows you to download as many videos as you want from more than a dozen different portals. Best of all is its simple interface, both clean and intuitive.
