What It Is
YouTube MP3 (ytmp3.nu) is a YouTube video to MP3 video converter. You can use ytmp3.nu to download YouTube audio in MP3 or videos in MP4 format. There’s also an option to download free files with YTMP3. Ytmp3.nu is one of the fastest and powerful YouTube audi and video converters.
Discussion
The homepage of ytmp3.nu has a field to paste the youtube.com video URL and then a button next to it to click to convert the video in the URL to an MP3 file. Beneath the field for converting the file is a description of what the site does. Beneath that again is a tutorial demonstrating how to download YouTube videos. Similar to sites such as onlymp3.to, the tutorial says all you need to convert the file to MP# is the YouTube URL that hosts the video and not the original video file itself.
