How to download a video from YouTube to MP4 or MP3?

 

There are many options, but I usually use easytube.pro . It's a handy service that allows you to save videos in MP4 with different quality (240p, 480p, 720p) or extract audio in MP3 (64-320 kbps) and M4A formats. The process is fast, the quality remains excellent, and the service itself is easy to use.
