VOB to TTA Converter
Processing entirely on your device — large files may take a moment.
DVD Video Object and True Audio exist for different jobs: VOB is the container inside every DVD-Video disc. Ripping a DVD leaves you with VOB files that ordinary players handle badly. Convert TTA to FLAC or MP3 for everyday playback.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the VOB format
VOB is the building block of DVD-Video: MPEG-2 program streams holding video, audio tracks, subtitles and menus, chopped into 1 GB chunks on the disc. Ripping a DVD means dealing with VOBs; the video inside is ordinary MPEG-2, usually with AC-3 or PCM audio.
Commercial DVDs add CSS encryption, which is both a technical and a legal matter: this site converts the unencrypted VOBs you own (home DVDs, camcorder discs), while defeating copy protection is a separate question governed by local law. Convert the VOB set to MP4 and the DVD's content becomes portable.
+ Strengths
- ✓Faithful DVD source material
- ✓Ordinary MPEG-2 inside — easy to convert
! Limitations
- −Chunked 1 GB files are awkward to handle
- −Commercial discs are CSS-encrypted
- −Standard-definition only
About the TTA format
TTA (True Audio) is a no-frills real-time lossless compressor: simple 32-bit crypto-free checksums, multi-threadable encoding and IDs at both frame and file level. It filled the lossless niche on slow connections and in Russian archive communities where FLAC arrived late.
Decoding is near-instant and lossless, so converting TTA to FLAC or MP3 costs nothing in fidelity — the audio is identical, the compatibility is finally universal.
+ Strengths
- ✓Real-time speed on modest hardware
- ✓Simple, well-documented container
- ✓Error-tolerant frame structure
! Limitations
- −Compression ratios behind modern codecs
- −Ecosystem largely inactive
- −Tagging support is weak
Why convert VOB to TTA?
There is a concrete reason this conversion exists: Chunked 1 GB files are awkward to handle TTA sidesteps that — Real-time speed on modest hardware If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this VOB to TTA converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for VOB to TTA?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of TTA, staying in sync with the video. If your VOB file has multiple audio tracks, the first one is used.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
