Add your M4V file
Drop one or more .m4v files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
M4V to MPEG
Pulling the soundtrack out of a .m4v video into .mpeg audio keeps what you can hear and drops the picture entirely. Free, private, and validated — the file never leaves your browser.

Pulling the soundtrack out of a .m4v video into .mpeg audio keeps what you can hear and drops the picture entirely. An .m4v file is Apple's flavor of the MPEG-4 container, used by iTunes for movies, TV episodes, and music videos. Structurally it is almost identical to .mp4, but the .m4v extension signaled iTunes-specific features such as chapter markers and, on purchased content, FairPlay copy protection.
An .mpeg file holds an MPEG program stream: video and audio multiplexed together using the original MPEG-1 or MPEG-2 standards. These files come from Video CDs, DVD-authoring workflows, and older capture hardware, and they remain readable by virtually every conversion tool. For this route the practical draw is universally decodable, with all underlying patents expired and simple, robust structure that tools have parsed for thirty years — balanced against mPEG-1 and MPEG-2 need roughly twice the bitrate of H.264 for comparable quality, which is worth knowing before you commit a large batch.
Why convert M4V to MPEG?
The usual reason to take .mpeg audio out of a .m4v file is that only the sound matters — a talk, interview, song, or podcast segment. Keeping the video stream would waste storage, and a dedicated audio file is easier to trim, tag, and play. On the source side, fairPlay-protected files play only in Apple apps on authorized devices, and no converter can open them; on the target side, the payoff is universally decodable, with all underlying patents expired, which is exactly what you want for handling digitized VHS or Video CD content.
M4V vs MPEG at a glance
| Aspect | MPEG-4 video (.m4v) | MPEG video (.mpeg) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | identical ISO base media layout to MP4, distinguished only by branding atoms and the extension | program streams were engineered for reliable storage media, in contrast to the error-hardened transport stream used for broadcast |
| Strongest at | playing back iTunes-era video libraries | handling digitized VHS or Video CD content |
| Weak spot | fairPlay-protected files play only in Apple apps on authorized devices, and no converter can open them | mPEG-1 and MPEG-2 need roughly twice the bitrate of H.264 for comparable quality |
| Metadata | full iTunes atom metadata: title, show, season, episode, artwork, chapters, and content ratings | the program stream carries essentially no descriptive metadata; the specification predates any notion of embedded titles or tags |
Pick MPEG as the output
Select .mpeg in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if MPEG is selectable, the route is real and validated.
Convert on your device
Press Convert. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid MPEG file. Outputs keep the original filename with the .mpeg extension.
M4V to MPEG questions, answered
Will converting M4V to MPEG lose quality?
Since m4v is container-oriented and mpeg is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .mpeg itself requires.
Is it private to convert M4V files here?
Yes — the .m4v file is processed inside your browser tab and never uploaded. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded. Close the tab and the file is gone from memory.
Where will the MPEG file work?
Desktop players on every operating system decode MPEG-1 and MPEG-2 program streams, and no licensing barriers remain. Browsers never adopted the format for the HTML5 video element, so web delivery requires conversion first.
Will the MPEG file be bigger or smaller than my M4V?
Much smaller — the video stream is usually 80–95% of a .m4v file's weight, and it is discarded entirely. The remaining audio is re-encoded at the bitrate implied by your quality setting.
What happens to the metadata in my M4V file?
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, full iTunes atom metadata: title, show, season, episode, artwork, chapters, and content ratings; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert MPEG back to M4V?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .m4v → .mpeg → .m4v is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
