Yup, it’s not easy to find such a program or site that would not degrade the sound after conversion. But this youtube to mp3 converter pleasantly surprised me. Here you can get a quality MP3 file without any bitrate cuts. The site is stable and fast, and the interface is very simple – you don’t need to understand it for a long time, just paste the link and you’re done. It’s ideal if you want to keep the original sound quality and don’t want to spend a lot of time on conversion.
