XM to TGZ Converter
Processing entirely on your device — large files may take a moment.
Convert TGZ exactly like TAR.GZ — unpack, repack or inspect. 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 TGZ format
TAR.GZ is the classic Unix distribution shape: a TAR bundle squeezed through gzip (DEFLATE-based). Every Linux package of source code, every Apache tarball, every data-science dataset arrives this way. Decompression is a pipeline — untar the gzip stream — and the format is understood everywhere Unix ideas went.
gzip compresses the whole archive as one stream, which keeps ratio decent for text-heavy trees but means reaching file #400 requires decompressing the previous 399. Modern alternatives (zstd) are faster at similar ratios, yet tar.gz remains the safest common denominator.
+Strengths
- ✓Universally understood on Unix-like systems
- ✓Good ratio for text and source trees
- ✓Preserves Unix permissions via TAR
!Limitations
- −Single stream — no random access
- −Slower than modern zstd
- −Two-step format (tar + gzip)
Why convert XM to TGZ?
Think of it as moving your file to the container that fits the job. Not a waveform — interpretation required TGZ works differently: Universally understood on Unix-like systems 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 TGZ 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 TGZ?
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 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.
Will converting XM to TGZ reduce audio quality?
If TGZ is lossless, the output contains everything the XM file contains — no further loss is added. If TGZ 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.
