Processing entirely on your device — large files may take a moment.
FastTracker II Module and FLAC Lossless Audio 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. Convert to FLAC when you want a permanent, lossless archive of your music.
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 FLAC format
FLAC (Free Lossless Audio Codec, Xiph, 2001) compresses audio to roughly 50–60% of its PCM size and restores every bit on playback — a ZIP for music that also carries proper tags, hi-res support up to 32-bit/655 kHz on paper (24-bit/192 kHz in practice) and full open-source pedigree. It is the archive format of digital music collections.
Support followed maturity: every serious player, modern Android (system-level), most cars and streaming purists' devices handle FLAC natively. Apple resisted for years but iOS 11+ plays it, with the caveat that iTunes/Apple Music syncing still prefers ALAC. The price of losslessness is size — about five times MP3 at comparable quality.
+ Strengths
- ✓Bit-perfect lossless with real compression
- ✓Hi-res capable (24-bit/192 kHz)
- ✓Open, unpatented, tag-native
! Limitations
- −~5× the size of lossy formats
- −Apple syncing prefers ALAC
- −Overkill for casual listening
Why convert XM to FLAC?
Think of it as moving your file to the container that fits the job. Not a waveform — interpretation required FLAC works differently: Bit-perfect lossless with real compression If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this XM to FLAC 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 FLAC?
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 FLAC reduce audio quality?
If FLAC is lossless, the output contains everything the XM file contains — no further loss is added. If FLAC 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.
