+Is downloading videos legal?
It depends on the video and where you live. Downloading is generally fine for videos you made yourself, videos under a Creative Commons or similar licence, and public-domain content. Downloading copyrighted videos without the owner's permission may break copyright law and YouTube's Terms of Service. MDYouTube does not host any videos; you are responsible for how you use the files. See our Terms of Use and DMCA policy for details.
+Should I choose MP4 or MP3?
Choose MP4 if you want to watch the video — it keeps both picture and sound. Choose MP3 if you only need the audio, for example music, podcasts or lectures; the file is much smaller and plays on any music player.
