3G2 to TAR.XZ Converter
Processing entirely on your device — large files may take a moment.
3GPP2 Mobile Video and XZ-compressed Tar exist for different jobs: 3G2 is the CDMA-era mobile video format — tiny, low-resolution clips from old feature phones. Produce a TAR.XZ for the smallest possible release artifact, or to match the format a build system expects.
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.
How 3G2 compares to TAR.XZ
| 3G2 | TAR.XZ | |
|---|---|---|
| Compression | H.263 / baseline H.264 | XZ / LZMA2 |
| Quality | Low resolution | Lossless, deterministic |
| Best for | Old mobile clips | Source releases, Linux packages |

About the 3G2 format
3G2 is the 3GPP2 variant of the mobile video format family, born on CDMA networks (Verizon, KDDI) where 3GP ruled GSM sides. Structurally it is a cousin of MP4 carrying H.263 or H.264 baseline video with QCELP/EVRC or AMR audio.
It shares 3GP's fate: low-resolution clips trapped on old phones. Conversion to MP4 is lossless in spirit — the pixels simply move into a container every modern device accepts.
+Strengths
- ✓Tiny files for its era
- ✓Structurally close to MP4 — clean conversions
!Limitations
- −Low resolution and quality ceiling
- −Obsolete outside old CDMA phones
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 3G2 to TAR.XZ?
Think of it as moving your file to the container that fits the job. Low resolution and quality ceiling 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 3G2 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 3G2 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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of TAR.XZ, staying in sync with the video. If your 3G2 file has multiple audio tracks, the first one is used.
Does converting 3G2 to TAR.XZ re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
