Convert MPEG to M4A
Updated Jul 2026
MPEG is a video format, and M4A holds audio only, so converting MPEG to M4A pulls the sound out of the video and drops the picture. Open the MPEG in a converter and export just the audio track as M4A. Doing this on your own computer means the video, which might show more than you'd want a stranger's server to see, never leaves your machine.

How to convert MPEG to M4A
- Open Morphjet and drag in the MPEG file (or a whole folder of them) you want the audio from.
- Choose M4A as the output format.
- Convert. Morphjet writes an M4A audio file next to your original, with the video dropped and nothing uploaded anywhere.
MPEG vs M4A: what actually changes
| MPEG | M4A | |
|---|---|---|
| Contains | Video and audio together | Audio only, no picture |
| File size | Large, video is most of the size | Much smaller, just the sound |
| Typical use | Broadcast video, DVDs | iTunes, Apple devices, voice memos |
| Quality | Lossy, an older broadcast and DVD standard | Lossy, but fine for speech and everyday listening |
| Opens in | Video players, DVD software, older broadcast equipment | iTunes, iPhone, Apple Music, most audio apps |
| Track info (title, artist, artwork) | Minimal, video files rarely carry it | Yes, supports proper audio tags |
When to convert, and when not to
Convert MPEG to M4A when you only want the sound from a video, like an interview, a lecture, a song, or narration, and you'd rather have a small audio file in iTunes or a voice memo app than the full video.
Keep the original MPEG if you still need the picture, since M4A is audio only and the video is gone for good once you convert.
Why not just use an online converter?
Old MPEG files often hold more than people remember, home videos, meeting recordings, things you'd rather not send to an unknown server just to pull out the audio. An online converter uploads the whole video to do that. Morphjet extracts the audio right on your own computer, so the video never leaves your machine.
Questions
Does converting MPEG to M4A lose quality?
The audio gets recompressed, so there's a small quality change, but for speech, interviews, or general listening it's not noticeable. If you need archival audio quality, a lossless format would serve you better.
Will I still have the video after converting?
No. M4A holds audio only, so the picture is dropped. Keep the original MPEG file if you might want the video again later.
Can I convert MPEG to M4A without uploading the file?
Yes. A desktop app like Morphjet reads the video and writes the audio locally, so nothing travels over the internet. You can do it with wifi off.
Why M4A instead of another audio format?
M4A is what iTunes, iPhone, and Apple's voice memo tools expect by default, so it's a natural choice if you're moving audio into that ecosystem.
Does the M4A keep any title or artist info from the MPEG?
Usually there isn't much to carry over, since video files rarely store detailed track tags. You can add title, artist, and artwork to the M4A afterward in most audio apps.
Morphjet converts MPEG, M4A, and 1,800+ other formats, all on your machine. Launching this July.
