TS to VOB

Pulling the soundtrack out of a .ts video into .vob audio keeps what you can hear and drops the picture entirely. A .ts file is an MPEG transport stream, the packetized format built to carry television through unreliable channels like antennas, satellites, and cable. DVR recordings, IPTV captures, and HLS streaming segments all use .ts, making it one of the most common raw broadcast formats people encounter.
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 TS to VOB?
The usual reason to take .vob audio out of a .ts 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, packet overhead runs several percent above an equivalent MP4; 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.
TS vs VOB at a glance
| Aspect | MPEG transport stream (.ts) | 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 | fixed 188-byte packets with sync bytes and continuity counters allow receivers to detect and skip corrupted data | an MPEG-2 program stream variant extended with navigation packs (PCI/DSI) that DVD players use for menus and seeking |
| Strongest at | saving recordings from DVRs and set-top boxes | backing up home-movie DVDs before the media degrades |
| Weak spot | packet overhead runs several percent above an equivalent MP4 | files split at roughly 1 GB boundaries and must be rejoined for continuous playback |
| Metadata | broadcast service tables (SDT/EIT) can carry channel names and program-guide data, but there is no field for user tagging | 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.
TS to VOB questions, answered
Will converting TS to VOB lose quality?
Since ts 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 TS files here?
Yes — the .ts 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 TS?
Much smaller — the video stream is usually 80–95% of a .ts 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 TS 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, broadcast service tables (SDT/EIT) can carry channel names and program-guide data, but there is no field for user tagging; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert VOB back to TS?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .ts → .vob → .ts is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
