Used to require Python to use on Windows, but has a standalone .exe now. It will download as well as convert, so you can easily get just mp3s from videos if you want. I think it will also process entire playlists, though I never bothered trying.

Depending on what you want it to do you might need ffmpeg for conversions.

there's a limit to the quality of downloads from youtube
youtube caps the quality to some amount. I don't really remember what the bitrate they limit it to is. Probably about 128k, which is acceptable enough for free music

Furthermore since youtube is owned by google, they convert everything uploaded to webm compatible formats. vp9, which is the most modern webm codec, is designed by google. the only compatible audio formats for webm are ogg and opus, which are basically interchangeable. However, this is a lossy format, and converting it to another lossy format, like mp3, will result in a permanent loss of data.

If possible, to maintain the best quality, you should download the best quality audio and not convert it. You can do this with youtube-dl with the command
youtube-dl youtube.com/watch/link -f bestaudio
and then not convert it. If you get audio in the format of a video-less webm you can use a program like ffmpeg to extract the normal format by using the -c:a copy option and save it as a .ogg or .opus file, depending on the format.

If you're trying to put these files on an old mp3 player they probably won't be able to play the files. Phones can maybe. If they can't you're just gonna be SOL and have to eat the loss in quality.
