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.
MPG to VOB
Pulling the soundtrack out of a .mpg video into .vob 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 .mpg video into .vob 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.
A .vob file is a Video Object from a DVD's VIDEO_TS folder, holding the disc's actual movie data. Each .vob multiplexes MPEG-2 video, audio, subtitle subpictures, and navigation commands, split into pieces of about one gigabyte to satisfy the DVD specification. For this route the practical draw is contains the disc's content exactly as authored, with all tracks intact and mPEG-2 decodes in any desktop player without licensing hurdles — balanced against files split at roughly 1 GB boundaries and must be rejoined for continuous playback, which is worth knowing before you commit a large batch.
Why convert MPG to VOB?
The usual reason to take .vob 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 contains the disc's content exactly as authored, with all tracks intact, which is exactly what you want for backing up home-movie DVDs before the media degrades.
MPG vs VOB at a glance
| Aspect | MPEG video (.mpg) | DVD video object (.vob) |
|---|---|---|
| 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 | an MPEG-2 program stream variant extended with navigation packs (PCI/DSI) that DVD players use for menus and seeking |
| Strongest at | working with recordings from PC TV capture cards | backing up home-movie DVDs before the media degrades |
| Weak spot | dated compression wastes space compared with any modern codec | files split at roughly 1 GB boundaries and must be rejoined for continuous playback |
| Metadata | nothing beyond the raw stream itself, so titles and descriptions live only in the filename | none inside the VOB itself; titles, chapters, and menu logic live in the accompanying IFO files on the disc |
Pick VOB as the output
Select .vob in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if VOB 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 VOB file. Outputs keep the original filename with the .vob extension.
MPG to VOB questions, answered
Will converting MPG to VOB lose quality?
Since mpg is container-oriented and vob is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .vob itself requires.
Is it private to convert MPG files here?
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.
Where will the VOB file work?
VLC and most desktop players open .vob files directly, but phones, TVs, and browsers do not, since the format assumes a DVD player's navigation logic. Home-burned discs convert freely to MP4, while retail discs carry CSS encryption.
Will the VOB file be bigger or smaller than my MPG?
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.
What happens to the metadata in my MPG 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, 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.
Can I convert VOB back to MPG?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .mpg → .vob → .mpg is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
