VOC to XZ Converter
Processing entirely on your device — large files may take a moment.
Unpack XZ into ZIP/TAR for tools that cannot read LZMA2. If your files are still in VOC format, this page is the shortcut: VOC is the Sound Blaster native audio format — the sound of every DOS game from the late 80s and early 90s.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

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 XZ format
XZ wraps the LZMA2 algorithm: the best ratio of the common Unix compressors, which is why distribution packages and source releases pick it when bandwidth matters more than CPU.
Windows Explorer and many cross-platform tools cannot open it — unpacking to ZIP or TAR makes the payload portable.
+Strengths
- ✓Highest common ratio
- ✓Standard for Linux packages
- ✓Integrity checks built in
!Limitations
- −Memory-hungry at high settings
- −Sparse support outside Linux

Frequently asked questions
Is this VOC to 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 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.
Is there a size limit for archive conversion?
There is no upload cap because nothing is uploaded — the practical limit is your device memory. A few hundred megabytes of unpacked content works comfortably on a modern computer.
Are the files inside my VOC archive modified?
No. Contents are unpacked in memory and repacked into XZ byte-for-byte — the conversion changes the container, never the files inside it.
