Drop one or more .webm 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.
WEBM to MPG
Pulling the soundtrack out of a .webm video into .mpg 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 .webm video into .mpg audio keeps what you can hear and drops the picture entirely. A .webm file is an open, royalty-free video container built specifically for the web. It restricts itself to free codecs, VP8, VP9, or AV1 for video with Vorbis or Opus for audio, so any browser can play a .webm without patent licensing concerns.
The .mpg extension is the three-letter spelling of .mpeg, applied to identical MPEG-1 or MPEG-2 program stream data. Files named .mpg and .mpeg are interchangeable at the byte level, so players and converters treat them the same and differ only in the label they display. For this route the practical draw is opens in everything from Windows Media Player to ffmpeg and decades of tooling make its behavior thoroughly predictable — balanced against dated compression wastes space compared with any modern codec, which is worth knowing before you commit a large batch.
Why convert WEBM to MPG?
The usual reason to take .mpg audio out of a .webm 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, older iPhones and legacy Safari versions cannot play it; on the target side, the payoff is opens in everything from Windows Media Player to ffmpeg, which is exactly what you want for working with recordings from PC TV capture cards.
WEBM vs MPG at a glance
| Aspect | WebM video (.webm) | MPEG video (.mpg) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | structured as a deliberately restricted subset of Matroska's EBML layout | byte-for-byte the same program stream format standardized in ISO/IEC 11172 and ISO/IEC 13818 |
| Strongest at | serving HTML5 video without codec license fees | working with recordings from PC TV capture cards |
| Weak spot | older iPhones and legacy Safari versions cannot play it | dated compression wastes space compared with any modern codec |
| Metadata | only a minimal set of Matroska tags such as title and language is defined for WebM; the spec deliberately omits attachments and rich tagging | nothing beyond the raw stream itself, so titles and descriptions live only in the filename |
Pick MPG as the output
Select .mpg in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if MPG 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 MPG file. Outputs keep the original filename with the .mpg extension.
WEBM to MPG questions, answered
Will converting WEBM to MPG lose quality?
Since webm is container-oriented and mpg is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .mpg itself requires.
Is it private to convert WEBM files here?
Yes — the .webm 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 MPG file work?
Any application that accepts .mpeg files accepts .mpg without complaint, since the difference is purely historical. That covers VLC, Windows Media Player, and QuickTime Player, but not the HTML5 video element in any browser.
Will the MPG file be bigger or smaller than my WEBM?
Much smaller — the video stream is usually 80–95% of a .webm 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 WEBM 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, only a minimal set of Matroska tags such as title and language is defined for WebM; the spec deliberately omits attachments and rich tagging; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert MPG back to WEBM?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .webm → .mpg → .webm is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
