But, before you start any new downloads, select video resolution from the dropdown menu as well as your file format. Choose from high or low definition videos. Otherwise, you can also just extract audio files from each video into MP3 format (particularly useful for saving music for offline listening). All your downloads save directly onto your download folder.
VidTube YouTube Downloader makes creating playlists a cinch. Now you'll always have a list of the videos you want to watch on hand without having to download them. That way, when you're using data you can save the videos you're interested in watching for later on from the comfort of your WiFi connection, rather than max out your dataplan.
