When to convert MP3 to M4A

Change an MP3 recording into an M4A container with AAC encoding. This is a new compressed copy rather than restored audio.

What the output contains

The M4A output contains AAC audio at up to 192 kbit/s. It does not produce Apple Lossless audio.

Keep the original recording. The converter does not promise identical file size, metadata, or playback support across every application.

Before using the converted file

Open the M4A in the destination application. Keep your MP3 and avoid repeated conversions between compressed formats.
