Google Takeout that will not only let you
download your YouTube videos in their original
high-resolution but also saves the files directly
to your Google Drive. Thus, you can start the
download process and it will save all your files,
big and small, to Google Drive in the background.
Once the files are in Drive, they’ll automatically
sync to your desktop that you can later upload to
other video websites.
To get started, go to this custom link, click
the Next button and choose Add to Drive as your
delivery method. That’s it. All you YouTube videos
will be zipped and added to the Takeout folder in
Drive in few hours. If the total size of your videos
exceeds 2GB, it will create multiple files of 2 GB each.
