VOC to JAR Converter
Processing entirely on your device — large files may take a moment.
Creative Sound Blaster VOC and Java Archive 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. Repack a JAR as ZIP to inspect classes and resources with any unzip tool.
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 JAR format
A JAR is a ZIP with Java manners: class files, a MANIFEST.MF, resources and optional signatures. Any tool that opens ZIPs can open it — but converting to a plain ZIP strips the “is this executable?” ambiguity and makes browsing the contents painless.
Useful for auditing dependencies, extracting embedded resources, or checking what a library actually ships before adding it to a build.
+Strengths
- ✓Standard Java delivery format
- ✓ZIP-based, tools abound
- ✓May carry signatures and manifests
!Limitations
- −Not a installer — just a package
- −Contents are class files, not source

Frequently asked questions
Is this VOC to JAR 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 JAR?
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 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.
Can I convert a whole folder of VOC files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
