AVI to 3G2 Converter
Processing entirely on your device — large files may take a moment.
AVI is Microsoft’s classic video container from the 90s. Files are large by modern standards but old devices and software still produce them. Converting 3G2 to MP4 rescues old phone videos for modern screens.
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.
How AVI compares to 3G2
| AVI | 3G2 | |
|---|---|---|
| Compression | Legacy codecs (DivX/Xvid era) | H.263 / baseline H.264 |
| Quality | Capped by its era | Low resolution |
| Compatibility | Legacy Windows tooling | Legacy CDMA phones |
| Best for | Reading old archives | Old mobile clips |

About the AVI format
AVI (Microsoft, 1992) is one of the oldest video containers still encountered. It has no native understanding of modern features — variable frame rates, modern codecs, subtitles, chapters — and stores everything through a 32-bit indexing system that caps reliable file sizes around 2 GB (OpenDML extensions patched some of this). Most AVIs you meet today are DivX/Xvid-era rips or old capture-card output.
There is no reason to produce AVI today; the realistic task is converting old libraries into MP4, which typically cuts file size by half or more at equal or better quality.
+ Strengths
- ✓Opens in legacy Windows tooling
- ✓Simple structure, decades of player support
! Limitations
- −Obsolete: no modern codecs or features by design
- −Large overhead, ~2 GB practical ceiling
- −Codec zoo inside — playback is guesswork
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
Why convert AVI to 3G2?
Converting makes sense where the strengths of 3G2 meet what AVI cannot give you. Tiny files for its era Meanwhile Obsolete: no modern codecs or features by design One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this AVI to 3G2 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 AVI to 3G2?
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.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of 3G2, staying in sync with the video. If your AVI file has multiple audio tracks, the first one is used.
