What Is This Tool?
This tool converts AVI video files into the 3G2 format, a mobile-optimized multimedia container designed for low-bitrate recording and playback on legacy mobile devices. It helps create smaller, mobile-friendly video files for sending via MMS or playback on older handsets while leveraging ISO base media format compatibility.
How to Use This Tool?
-
Upload your AVI video file using the upload interface
-
Select 3G2 as the output format from the available options
-
Click the convert button to start the conversion process
-
Download the converted 3G2 file once the process completes
-
Play or send the 3G2 video on supported mobile devices or messaging apps

-
Supports common mobile audio and video codecs like AMR, EVRC, QCELP, MPEG-4, and H.264
-
Browser-based and easy to use without software installation
-
Preserves compatibility with legacy mobile phones and CDMA devices
Examples
-
Convert a camcorder-exported AVI clip to 3G2 for sending via MMS to legacy mobile phones
-
Transcode an AVI training video to 3G2 for playback on older CDMA handsets used in field deployments
-
Prepare short legacy Windows AVI videos as mobile-friendly clips optimized for low-bandwidth mobile networks
Common Use Cases
-
Sending video clips over mobile messaging systems with limited bandwidth
-
Playing videos on older feature phones and CDMA devices supporting 3GPP2 containers
-
Interchanging mobile-optimized media between handset tools and legacy workflows
-
Converting archived AVI footage to smaller files for mobile storage with acceptable quality
Tips & Best Practices
-
Check codec compatibility as some AVI codecs may not map well to 3G2 supported codecs
-
Use this tool when creating videos for legacy or low-bandwidth mobile devices
-
Be aware that conversion may reduce video quality due to lossy compression
-
Avoid relying on metadata or subtitles since both AVI and 3G2 have limited support
-
Consider segmenting large AVI files before converting due to size and format limits
Limitations
-
Conversion may reduce video fidelity due to use of lossy mobile codecs in 3G2
-
Some AVI codecs may not convert cleanly to 3G2, causing playback issues
-
Limited support for advanced metadata, chapters, subtitles, and auxiliary tracks
-
3G2 files are less supported on modern desktop and web players compared to MP4
-
Large AVI files may require re-encoding decisions because of file size constraints
Frequently Asked Questions
-
What is the main benefit of converting AVI to 3G2?
-
The conversion produces mobile-optimized, low-bitrate videos compatible with legacy handsets and low-bandwidth delivery systems like MMS.
-
Will converting from AVI to 3G2 affect video quality?
-
Yes, since 3G2 commonly uses lossy codecs, converting from higher-quality AVI sources may result in reduced fidelity.
-
Can I play 3G2 files on modern desktop players?
-
3G2 is less widely supported on modern desktop and web players compared to formats like MP4, so playback options may be limited.
