VOC to MKV Converter
Processing entirely on your device — large files may take a moment.
MKV is ideal for archiving movies with multiple audio tracks and subtitles intact. 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.

About the MKV format
MKV (Matroska) is the open container that refuses to say no: virtually any video codec, multiple audio tracks, multiple subtitle streams, chapters, attachments and menu structure in one file. It became the de facto standard for movie rips, anime releases and personal archives precisely because nothing needs to be thrown away.
The same generosity is its compatibility risk: smart players (VLC, mpv) handle everything, but smart TVs, consoles and car systems choke on exotic codec combinations inside MKV. It is also not a streaming standard, so web delivery runs through its subset, WebM.
+ Strengths
- ✓Unlimited tracks: audio, subtitles, chapters, attachments
- ✓Open specification, no licensing
- ✓Ideal archival container — nothing is lost
! Limitations
- −Device playback is hit-or-miss outside smart players
- −Not web/streaming native

Frequently asked questions
Is this VOC to MKV 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 MKV?
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.
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.
Will converting VOC to MKV reduce audio quality?
If MKV is lossless, the output contains everything the VOC file contains — no further loss is added. If MKV 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.
