This site offers a very interesting service, I give you one example, let’s say, hypothetically, that I want to download a video from youtube that has this address:
Simply enter a ’10’ before youtube, like this:
being careful that it is not on ssl protocol (https: //), at this point, the site provides to offer you the possibility to download the video.
I honestly do not know if the video is handled server-side, the fact is that is downloaded from their server and not directly from youtube.
Personally I do not mind having another service that provides the ability to download video, as it is our passion, if you want to recommend some other service do not hesitate to comment on this post
