3G2 to TAR.GZ Converter
Processing entirely on your device — large files may take a moment.
3G2 is the CDMA-era mobile video format — tiny, low-resolution clips from old feature phones. 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.
How 3G2 compares to TAR.GZ
| 3G2 | TAR.GZ | |
|---|---|---|
| Compression | H.263 / baseline H.264 | gzip (DEFLATE) |
| Best for | Old mobile clips | Source releases and backups |

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.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 3G2 to TAR.GZ?
There is a concrete reason this conversion exists: Low resolution and quality ceiling TAR.GZ sidesteps that — Universally understood on Unix-like systems If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this 3G2 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 3G2 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.
Does converting 3G2 to TAR.GZ 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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of TAR.GZ, staying in sync with the video. If your 3G2 file has multiple audio tracks, the first one is used.
