Steps

  1. 1

    Inspect the M4A if you need to know whether it contains AAC or ALAC.

  2. 2

    Choose it in the local M4A-to-MP3 tool.

  3. 3

    Select the MP3 bitrate and run the conversion.

  4. 4

    Download and verify playback in the target Windows app.

Before you start

  • AAC-to-MP3 is lossy-to-lossy.
  • ALAC is lossless and should be preserved as a master when possible.

Work from a copy, keep the original, and verify the downloaded result before removing any source file. Browser-local output is temporary until you download it.
