M4A is AAC audio in an MP4 container, used by iTunes, Apple Music and many voice recorders. It sounds better than MP3 at the same size. MP3 is the universal compressed audio format. It plays on every phone, car stereo and music app.
Converting to MP3 gives you audio that plays on absolutely everything. The conversion happens entirely in your browser, so your files are never uploaded and there’s no size limit beyond your device’s memory.
