I wouldn't say I like converting files from MP4 to MP3, but I have no other choice. MP3 files have much worse sound quality. So I wouldn't say I like that format. But I have a pretty old radio in my car that only reads files in that format. At one time, I had to find a program or website to help me do that. I was lucky because my friend found this site https://convertr.org/m4a-to-mp3. The loss of file quality is minimal, so I consider this site one of the best. If you are looking for something like this, I advise you to try it.
