VOC to BZ2 Converter
Processing entirely on your device — large files may take a moment.
VOC is the Sound Blaster native audio format — the sound of every DOS game from the late 80s and early 90s. Convert BZ2 to ZIP or TAR when modern tools need a friendlier container.
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 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.

- ✓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 BZ2 format
BZ2 applies the Burrows–Wheeler transform: slower than gzip but noticeably smaller, which is why Wikipedia database dumps and old source tarballs still arrive as .bz2.
Few GUI tools ship a bz2 reader these days, so converting the contents into a ZIP or TAR is the practical way to hand the payload to someone else.
+Strengths
- ✓Better ratio than gzip
- ✓Common in dumps and archives
- ✓Mature, stable format
!Limitations
- −Slow to compress and decompress
- −Declining tool support
Why convert VOC to BZ2?

Frequently asked questions
Is this VOC to BZ2 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 BZ2?
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.
Are the files inside my VOC archive modified?
No. Contents are unpacked in memory and repacked into BZ2 byte-for-byte — the conversion changes the container, never the files inside it.
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.
