XM to ALAC Converter
Processing entirely on your device — large files may take a moment.
Convert ALAC to FLAC for non-Apple players, or MP3 for sharing. If your files are still in XM format, this page is the shortcut: XM is the FastTracker II module format — the tracker scene's workhorse, with instruments, envelopes and effects baked into the file.
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 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 ALAC format
ALAC (Apple Lossless Audio Codec) is Apple's FLAC equivalent: bit-exact lossless compression inside an MP4 container, opened-source in 2011 and now native on every Apple device and most server-side pipelines. It is what iTunes Store sells as "lossless" and what iPhone recordings encode to by default.
For non-Apple players FLAC is the safer target, and conversion is sample-exact in both directions — the decode is handled by ffmpeg's native ALAC decoder without any Apple runtime.
+ Strengths
- ✓Native on every Apple device
- ✓Open source since 2011
- ✓Reasonable sizes inside MP4
! Limitations
- −Outside Apple ecosystems FLAC wins
- −Slightly worse ratios than FLAC
- −Confusing .m4a extension doubles as lossy
Why convert XM to ALAC?
Converting makes sense where the strengths of ALAC meet what XM cannot give you. Native on every Apple device 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 ALAC 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 ALAC?
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 ALAC reduce audio quality?
If ALAC is lossless, the output contains everything the XM file contains — no further loss is added. If ALAC 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.
