Add your MPG file
Drop one or more .mpg 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.
Pulling the soundtrack out of a .mpg video into .ogv audio keeps what you can hear and drops the picture entirely. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Pulling the soundtrack out of a .mpg video into .ogv audio keeps what you can hear and drops the picture entirely. 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.
An .ogv file is video packed in the Ogg container, typically compressed with the Theora codec and paired with Vorbis audio. The .ogv extension separated video from Ogg audio when Xiph.Org split its file naming, and it appears mostly in open-source projects and Wikipedia's media archives. For this route the practical draw is royalty-free from container to codec with no patent baggage and streams and seeks well despite its age — balanced against theora's compression is a full generation behind even VP8, which is worth knowing before you commit a large batch.
The usual reason to take .ogv audio out of a .mpg 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, dated compression wastes space compared with any modern codec; on the target side, the payoff is royalty-free from container to codec with no patent baggage, which is exactly what you want for playing media downloaded from Wikimedia Commons.
| Aspect | MPEG video (.mpg) | Ogg video (.ogv) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | byte-for-byte the same program stream format standardized in ISO/IEC 11172 and ISO/IEC 13818 | uses Ogg's page-and-packet framing, which supports live streaming and survives truncation gracefully |
| Strongest at | working with recordings from PC TV capture cards | playing media downloaded from Wikimedia Commons |
| Weak spot | dated compression wastes space compared with any modern codec | theora's compression is a full generation behind even VP8 |
| Metadata | nothing beyond the raw stream itself, so titles and descriptions live only in the filename | vorbis comments in the audio stream carry artist and title tags, and the Ogg Skeleton track can describe the streams themselves |

Select .ogv in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if OGV is selectable, the route is real and validated.
Press Convert. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid OGV file. Outputs keep the original filename with the .ogv extension.
Since mpg is container-oriented and ogv is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .ogv itself requires.
Yes — the .mpg 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.
Firefox retains Theora playback and Chromium-based browsers have begun deprecating theirs, while Safari and mobile platforms never supported .ogv at all. VLC and ffmpeg decode it everywhere, making conversion to WebM or MP4 straightforward.
Much smaller — the video stream is usually 80–95% of a .mpg file's weight, and it is discarded entirely. The remaining audio is re-encoded at the bitrate implied by your quality setting.
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, nothing beyond the raw stream itself, so titles and descriptions live only in the filename; none of it is transmitted anywhere because the file never leaves your browser.
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .mpg → .ogv → .mpg is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
