VOC to TAR.XZ Converter
Processing entirely on your device — large files may take a moment.
Creative Sound Blaster VOC and XZ-compressed Tar exist for different jobs: VOC is the Sound Blaster native audio format — the sound of every DOS game from the late 80s and early 90s. 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.

About the VOC format
VOC is the Creative Sound Blaster format — if a DOS game made a sound between 1989 and 1994, it was probably a VOC: 8-bit samples at exotic sample rates, with loop points, silence blocks and hardware-specific appendices that made each card sing differently.
ffmpeg decodes the standard sample blocks and converts VOC to WAV or MP3 — the cheapest time machine for retro-game audio.
+Strengths
- ✓The DOS gaming era's audio format
- ✓Unique features: loops, silence, transfer blocks
- ✓Simple to decode
!Limitations
- −8-bit/11kHz era fidelity
- −Creative hardware extensions lost on convert
- −Rarely produced after 1995
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 VOC to TAR.XZ?
Converting makes sense where the strengths of TAR.XZ meet what VOC cannot give you. Best compression ratio of the tar family Meanwhile 8-bit/11kHz era fidelity One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this VOC 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 VOC 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 converting VOC to TAR.XZ reduce audio quality?
If TAR.XZ is lossless, the output contains everything the VOC file contains — no further loss is added. If TAR.XZ is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
