About the XM format
XM (Extended Module) is FastTracker II's evolution of MOD: 16-bit samples, volume/panning envelopes, arpeggio and effect columns — the tracker format that scored the demoscene of the late 90s and still powers chip music communities.
Rendering XM to MP3/WAV through libopenmpt's engine reproduces the song with its instruments and effects intact — the same interpretation FT2 users heard, normalized into a universally playable waveform.
+ Strengths
- ✓16-bit samples and rich effects
- ✓Standard of the late-90s demo scene
- ✓Accurate libopenmpt rendering
! Limitations
- −Not a waveform — interpretation required
- −Filter quirks vary between players
- −Compression is minimal
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

Frequently asked questions
Is this XM to VOC 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 XM to VOC?
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 XM to VOC reduce audio quality?
If VOC is lossless, the output contains everything the XM file contains — no further loss is added. If VOC 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.
Can I convert a whole folder of XM 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.
