Add your MPEG file
Drop one or more .mpeg 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.
MPEG to WMV
Pulling the soundtrack out of a .mpeg video into .wmv 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 .mpeg video into .wmv audio keeps what you can hear and drops the picture entirely. 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.
A .wmv file contains Windows Media Video, Microsoft's proprietary codec family, almost always wrapped in an ASF container. The extension was everywhere on Windows XP-era PCs, from downloaded clips to Movie Maker exports, but it has faded as MP4 became universal. For this route the practical draw is excellent support across legacy Windows software and vC-1 encodes hold up reasonably well for their age — balanced against effectively abandoned by Microsoft itself, which is worth knowing before you commit a large batch.
Why convert MPEG to WMV?
The usual reason to take .wmv audio out of a .mpeg 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, mPEG-1 and MPEG-2 need roughly twice the bitrate of H.264 for comparable quality; on the target side, the payoff is excellent support across legacy Windows software, which is exactly what you want for playing old Movie Maker projects and family archives.
MPEG vs WMV at a glance
| Aspect | MPEG video (.mpeg) | Windows Media video (.wmv) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | program streams were engineered for reliable storage media, in contrast to the error-hardened transport stream used for broadcast | aSF container carrying WMV1, WMV2, or WMV3 (VC-1) video, typically with WMA audio |
| Strongest at | handling digitized VHS or Video CD content | playing old Movie Maker projects and family archives |
| Weak spot | mPEG-1 and MPEG-2 need roughly twice the bitrate of H.264 for comparable quality | effectively abandoned by Microsoft itself |
| Metadata | the program stream carries essentially no descriptive metadata; the specification predates any notion of embedded titles or tags | aSF content-description attributes hold title, author, copyright, and rating fields, plus extended attributes used by Windows Media Player libraries |
Pick WMV as the output
Select .wmv in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if WMV 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 WMV file. Outputs keep the original filename with the .wmv extension.
MPEG to WMV questions, answered
Will converting MPEG to WMV lose quality?
Since mpeg is container-oriented and wmv is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .wmv itself requires.
Is it private to convert MPEG files here?
Yes — the .mpeg 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 WMV file work?
Windows 10 and 11 still play .wmv out of the box, but macOS dropped support after the QuickTime plugin era ended, and no browser or mobile OS will touch it. Conversion to MP4 is required for web or cross-platform use.
Will the WMV file be bigger or smaller than my MPEG?
Much smaller — the video stream is usually 80–95% of a .mpeg 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 MPEG 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, the program stream carries essentially no descriptive metadata; the specification predates any notion of embedded titles or tags; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert WMV back to MPEG?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .mpeg → .wmv → .mpeg is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
