Why 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.

  • Why use M4A. M4A suits voice memos from iPhones, Apple Music libraries, and compact voice files.
  • What you get. The M4A output contains AAC audio at up to 192 kbit/s. It is not Apple Lossless audio. Keep the original. The converted file can differ in size and metadata, and some apps may still not play it.
  • 品質. Converting MP3 to M4A compresses the audio again and can lower its quality. Use it only when the destination needs M4A, and keep the MP3 original.
  • Your rights. Convert only files you own or have permission to use.
