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 .ogg 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 .ogg 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 .ogg file almost always means Vorbis-compressed audio in the Ogg container, the free-software world's answer to MP3. The .ogg extension originally covered any Xiph media; audio kept the name when video moved to .ogv, and game developers and Wikipedia still lean on it heavily. For this route the practical draw is patent-free from its first release and strong quality at mid-range bitrates — balanced against apple's Music app and iOS offer no native playback, which is worth knowing before you commit a large batch.
The usual reason to take .ogg 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 patent-free from its first release, which is exactly what you want for shipping game audio assets without codec royalties.
| Aspect | MPEG video (.mpg) | Ogg audio (.ogg) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Lossy — discards detail it judges invisible to shrink files |
| How it stores data | byte-for-byte the same program stream format standardized in ISO/IEC 11172 and ISO/IEC 13818 | vorbis is an MDCT-based lossy codec tuned through a quality scale (-q) rather than fixed bitrates |
| Strongest at | working with recordings from PC TV capture cards | shipping game audio assets without codec royalties |
| Weak spot | dated compression wastes space compared with any modern codec | apple's Music app and iOS offer no native playback |
| Metadata | nothing beyond the raw stream itself, so titles and descriptions live only in the filename | vorbis comments, the flexible key=value system shared with FLAC and Opus, plus METADATA_BLOCK_PICTURE for embedded cover art |

Select .ogg in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if OGG 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 OGG file. Outputs keep the original filename with the .ogg extension.
Since mpg is container-oriented and ogg is lossy-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .ogg 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.
Chrome, Firefox, and Edge have decoded Ogg Vorbis for many years, and Android plays it natively, while Safari and iOS remained the notable holdouts until only recently. Dedicated players such as VLC and foobar2000 cover the desktop everywhere.
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.
