Converting ALAC to MP3 trades detail for size, and the trade is permanent. Encode at the top of the 128 to 320 kbps range if the file will be edited again later. Size falls from about 6 MB per minute to around 1.7 MB per minute.
ALAC can carry sample rates up to 192 kHz, but MP3 tops out at 48 kHz. High-resolution sources are resampled down on the way through.
Multichannel sources need care: MP3 handles at most 2 channels where ALAC allows 8, so anything wider is downmixed.
This conversion buys reach. Unlike ALAC, MP3 is natively supported on web browsers, Windows, Android, and smart TVs, which is usually the reason people convert in this direction.
This conversion moves the file toward a different purpose: ALAC suits long-term archiving, the Apple ecosystem, audiophile listening, whereas MP3 is chosen for music libraries, podcasts, sharing with anyone.
Converting ALAC to MP3 means moving audio out of the MPEG-4 (.m4a) container, introduced in 2004, and into MPEG-1/2 Audio Layer III, which arrived in 1993. The two were designed with different priorities, and that is what determines whether this conversion costs you quality, storage, or compatibility.
Developed by Apple in 2004, ALAC carries losslessly compressed audio (ALAC). That sets the upper bound on what any conversion can preserve.
MP3 was introduced by Fraunhofer IIS / MPEG in 1993. It holds lossy-compressed audio (MP3) and plays natively on web browsers, Windows, macOS, iOS, Android, and smart TVs.
