XI to TAR.GZ Converter
Processing entirely on your device — large files may take a moment.
FastTracker II Instrument and Gzipped TAR Archive exist for different jobs: XI is the FastTracker II instrument format — 8/16-bit sample instruments with loop points, carried inside every XM tracker module kit. TAR.GZ is what open-source projects and Linux servers expect to receive.
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.

- −Keep the original for archival round-trips
About the TAR.GZ 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 XI to TAR.GZ?
Converting makes sense where the strengths of TAR.GZ meet what XI cannot give you. Universally understood on Unix-like systems Meanwhile Legacy niche format One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this XI to TAR.GZ 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 XI to TAR.GZ?
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 XI to TAR.GZ reduce audio quality?
If TAR.GZ is lossless, the output contains everything the XI file contains — no further loss is added. If TAR.GZ 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.
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.
