VOB to TAR.XZ Converter
Processing entirely on your device — large files may take a moment.
DVD Video Object and XZ-compressed Tar 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. Produce a TAR.XZ for the smallest possible release artifact, or to match the format a build system expects.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How VOB compares to TAR.XZ
| VOB | TAR.XZ | |
|---|---|---|
| Compression | MPEG-2 program stream | XZ / LZMA2 |
| Quality | DVD standard definition | Lossless, deterministic |
| Best for | DVD content handling | Source releases, Linux packages |

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 TAR.XZ format
TAR.XZ pairs the tar container with XZ (LZMA2) compression — the highest-ratio member of the tar family and the de-facto release format of modern Linux distributions. The same source tree that lands 5% smaller than TAR.BZ2 and 20% smaller than TAR.GZ is why kernel.org and GNU mirrors standardised on it.
The trade is CPU time: XZ compresses slow (dictionary sizes up to 64 MB) but decompresses fast, which makes it ideal for one-time releases that get downloaded millions of times. When you need speed instead, TAR.GZ or TAR.ZSTD are the neighbouring picks.
+Strengths
- ✓Best compression ratio of the tar family
- ✓Standard release artifact of Linux distros
- ✓Fast decompression despite slow compression
!Limitations
- −Compression is CPU-heavy and single-threaded by default
- −Larger toolchain footprint than gzip on tiny systems
Why convert VOB to TAR.XZ?
Think of it as moving your file to the container that fits the job. Chunked 1 GB files are awkward to handle TAR.XZ works differently: Best compression ratio of the tar family If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this VOB to TAR.XZ 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 TAR.XZ?
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 TAR.XZ, staying in sync with the video. If your VOB file has multiple audio tracks, the first one is used.
Does converting VOB to TAR.XZ re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
