What to expect
- If your
.mkaalready contains AAC audio, useffmpeg -i in.mka -c:a copy out.m4ato remux without re-encoding - lossless and instant. - Converting from any lossy format (MP3, Opus, Vorbis) to AAC always reduces quality slightly - each encode generation loses information that cannot be recovered.
- MKA can hold multiple audio tracks, chapters, and attachments; only the first (or default) audio track is extracted unless you specify otherwise.
Frequently asked questions
Can I convert MKA to M4A without losing quality?
Yes, but only if the MKA already contains AAC audio - then remux with
ffmpeg -i in.mka -c:a copy out.m4a and nothing is re-encoded. If the source is FLAC, MP3, or Opus, converting to AAC always involves some quality loss.Will the M4A play on iPhone and Apple Music?
Yes - AAC in M4A is Apple's own audio format and plays natively on all Apple devices and in iTunes/Apple Music without any additional software.
Does the conversion keep tags and cover art?
FFmpeg copies standard tags (title, artist, album) and usually transfers embedded cover art; chapter markers and secondary audio tracks are not preserved by default.
What bitrate should I use when converting to M4A?
128 kbps AAC is transparent for most listeners; 256 kbps matches the quality of a typical iTunes purchase if the source allows it.
