XM to MKV Converter
Processing entirely on your device — large files may take a moment.
FastTracker II Module and Matroska Video exist for different jobs: XM is the FastTracker II module format — the tracker scene's workhorse, with instruments, envelopes and effects baked into the file. MKV is ideal for archiving movies with multiple audio tracks and subtitles intact.
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 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 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
Why convert XM to MKV?
Converting makes sense where the strengths of MKV meet what XM cannot give you. Unlimited tracks: audio, subtitles, chapters, attachments Meanwhile Not a waveform — interpretation required One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this XM 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 XM 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.
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.
Will converting XM to MKV reduce audio quality?
If MKV is lossless, the output contains everything the XM 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.
