GSM to TAR.XZ Converter
Processing entirely on your device — large files may take a moment.
GSM 06.10 is the 1990s mobile-telephony speech codec — 13 kbit/s audio that VoIP systems and old answering machines still emit. Produce a TAR.XZ for the smallest possible release artifact, or to match the format a build system expects.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the GSM format
GSM 06.10 is the speech codec of the original GSM mobile network — 13 kbit/s RPE-LTP that made digital cellphone calls possible in 1991 and still lives inside VoIP systems, old answering machines and Asterisk PBX recordings.
It is lossy speech, not music: converting GSM to WAV or MP3 preserves intelligibility perfectly while finally letting desktop players open the file without special codecs.
+Strengths
- ✓Tiny bitrate for speech intelligibility
- ✓Ubiquitous in telephony systems
- ✓Decodes natively via ffmpeg
!Limitations
- −Speech-only quality — music falls apart
- −13 kbit/s artifacts are audible
- −8000 Hz sample rate only
About the TAR.XZ format
TAR.XZ pairs the tar container with XZ (LZMA2) compression — the highest-ratio member of the tar family and the de-facto release format of modern Linux distributions. The same source tree that lands 5% smaller than TAR.BZ2 and 20% smaller than TAR.GZ is why kernel.org and GNU mirrors standardised on it.
The trade is CPU time: XZ compresses slow (dictionary sizes up to 64 MB) but decompresses fast, which makes it ideal for one-time releases that get downloaded millions of times. When you need speed instead, TAR.GZ or TAR.ZSTD are the neighbouring picks.
+Strengths
- ✓Best compression ratio of the tar family
- ✓Standard release artifact of Linux distros
- ✓Fast decompression despite slow compression
!Limitations
- −Compression is CPU-heavy and single-threaded by default
- −Larger toolchain footprint than gzip on tiny systems
Why convert GSM to TAR.XZ?
Think of it as moving your file to the container that fits the job. Speech-only quality — music falls apart TAR.XZ works differently: Best compression ratio of the tar family If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this GSM to TAR.XZ 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 GSM to TAR.XZ?
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.
Can I convert a whole folder of GSM 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.
