What is Legally Best YouTube downloader?

I saw people also download videos from YouTube by various apk like tubemate, snaptube, vidmate etc. Is those legal?

If yes, I have no question.

If not, What is the legal youtube Video downloader.

We know that many youtube downloaders are illegal but all still use them. I am also use it. Because it is convenient way to watch favorite videos offline. I used many of them but like this program which it free and easy in use.

i think you can try some online youtube downloaders, I use this one called DumpMedia Video Downloader, it has online and offline versions, and it allows you to download in batch. a very convenient tool.

I use Videoder and it is a free video downloader available for Windows and Android.

Personally, I use the Videoder tool on my device. I think it’s the best…

KeepVid is the go-to website to download YouTube videos in MP4 format. Not only individual videos, but the tool also lets you conveniently download complete YouTube playlists in one go.

There are many but as you say legal i latterly laugh downloading is not legal :xD
But you can use youtube to mp3 320kbps its best so far.
