Add your VOB file
Drop one or more .vob 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.
VOB to OGG
Pulling the soundtrack out of a .vob video into .ogg 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 .vob video into .ogg audio keeps what you can hear and drops the picture entirely. 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.
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.
Why convert VOB to OGG?
The usual reason to take .ogg audio out of a .vob 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, files split at roughly 1 GB boundaries and must be rejoined for continuous playback; 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.
VOB vs OGG at a glance
| Aspect | DVD video object (.vob) | 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 | an MPEG-2 program stream variant extended with navigation packs (PCI/DSI) that DVD players use for menus and seeking | vorbis is an MDCT-based lossy codec tuned through a quality scale (-q) rather than fixed bitrates |
| Strongest at | backing up home-movie DVDs before the media degrades | shipping game audio assets without codec royalties |
| Weak spot | files split at roughly 1 GB boundaries and must be rejoined for continuous playback | apple's Music app and iOS offer no native playback |
| Metadata | none inside the VOB itself; titles, chapters, and menu logic live in the accompanying IFO files on the disc | vorbis comments, the flexible key=value system shared with FLAC and Opus, plus METADATA_BLOCK_PICTURE for embedded cover art |
Pick OGG as the output
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.
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 OGG file. Outputs keep the original filename with the .ogg extension.
VOB to OGG questions, answered
Will converting VOB to OGG lose quality?
Since vob 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.
Is it private to convert VOB files here?
Yes — the .vob 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 OGG file work?
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.
Will the OGG file be bigger or smaller than my VOB?
Much smaller — the video stream is usually 80–95% of a .vob 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 VOB 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, none inside the VOB itself; titles, chapters, and menu logic live in the accompanying IFO files on the disc; none of it is transmitted anywhere because the file never leaves your browser.
