M4A vs MP3: which should you use?
M4A and MP3 are basically containers (think of boxes) for audio data; Inside they use codecs to encode the audio. M4A usually uses AAC (lossy) or sometimes ALAC (lossless). “Lossy” means it throws away tiny details to shrink the file—good for size, but you can’t get those details back; “lossless” keeps every bit of the original. MP3 is always lossy but plays almost everywhere. So use MP3 for maximum compatibility, and keep M4A with ALAC if you need exact, original quality — Converting AAC to MP3 won’t make it sound better but increases the compatibility.
Convert M4A to MP3 on Windows
Yes there are various ways. The easiest way is Converter App. If you want to go for offline conversion: in Apple Music or iTunes set Import Settings to MP3, then use File, Convert, Create MP3 Version. That should do the job offline.
Any downsides?
Re-encoding a lossy M4A (AAC) to MP3 adds a small quality loss. Use Auto or 192 kbps for music, 128 kbps for podcasts. If your source is ALAC, keep a copy of the original if you need lossless.
