Convert M4V to OGG
Updated Jul 2026
M4V is Apple's video format for movies and TV shows, and OGG is an audio-only format used by games and many media players. Since OGG can't hold video, converting M4V to OGG pulls out just the audio track and re-encodes it as Ogg Vorbis. Doing this on your own computer means the file never has to leave your machine.

How to convert M4V to OGG
- Open Morphjet and drag in the M4V file, or a whole folder of them.
- Choose OGG as the output format. Morphjet takes the audio track and converts it, since OGG has no way to store video.
- Convert. The OGG file is written next to the original, and nothing leaves your machine.
M4V vs OGG: what actually changes
| M4V | OGG | |
|---|---|---|
| Contains video | Yes | No, audio only |
| File size | Larger, video plus audio | Much smaller, audio only |
| Quality | Lossy video and audio | Lossy audio, re-encoded from the source track |
| Compatibility | Apple devices and apps built around iTunes video | Games, open media players, and most non-Apple audio software |
| Copy protection | Purchased or rented titles are often protected | Not applicable, it's a plain audio file |
| Typical use | Movies and TV shows | Game audio, soundtracks, background music |
When to convert, and when not to
Convert M4V to OGG when you only want the sound from a video, like a lecture recording, a home movie's audio, or a soundtrack, and you need it in a format that games or non-Apple audio players can use.
If you actually need the picture, don't convert to OGG. It's an audio-only format, so the entire video track is thrown away in the process.
Why not just use an online converter?
M4V files are often personal, home movies, recorded lectures, or video you'd rather not hand to a stranger's server just to pull out the audio. An online converter uploads the whole video to do that. Converting on your own computer means the video and the audio extracted from it stay on your machine the entire time.
Questions
Does converting M4V to OGG keep the video?
No. OGG is an audio-only format, so the conversion keeps just the soundtrack and discards the picture entirely.
Will the audio quality be worse after converting?
A little. The audio inside an M4V is already compressed, so re-encoding it to Ogg Vorbis is a lossy-to-lossy conversion, which loses a small, generally unnoticeable amount of quality.
Can I convert a movie or show I bought from iTunes?
Usually not. Purchased and rented iTunes video is often protected against copying, and no local converter, Morphjet included, can get around that protection.
Does the OGG file keep any metadata from the M4V?
Ogg Vorbis supports its own tags for things like title and artist, but most of what's stored in an M4V, like chapter markers or video info, doesn't carry over since it doesn't apply to an audio-only file.
Can this be done without an internet connection?
Yes. Since Morphjet converts the file locally, you can do this with your wifi off.
