Convert 3G2 files online for free
The converter easily converts your 3G2 file to various formats - free and online. No QuickTime Player or or other Video software needed.
The converter also works in reverse, so you can convert other "Mobile Multimedia Container" formats to 3G2 without using software like QuickTime Player or a similar tool.
The .3G2 file extension represents a multimedia container format developed by the 3rd Generation Partnership Project 2 (3GPP2). It was the standard video format for CDMA-based mobile phones (common with carriers like Verizon, Sprint, and KDDI) during the flip-phone and early smartphone era. While technically similar to the GSM-based 3GP format, 3G2 files accommodate specific audio streams like EVRC and SMV designed to minimize bandwidth usage on early 3G networks.
The Problem: Today, 3G2 files are effectively obsolete relics. Because they were heavily compressed for 2000s-era mobile data limits, the video resolution is typically very low (often 176x144 QCIF), appearing blocky on modern screens. More frustratingly, modern media players (such as Windows Media Player or QuickTime) often lack the legacy codecs required to decode the specific CDMA audio tracks, resulting in silent playback or "file corrupted" errors. You generally cannot import these directly into editors like Adobe Premiere Pro without transcoding them first.
The Solution: To preserve these memories or use them in modern projects, conversion is the most pragmatic approach:
Use Convert.Guru to open and convert your 3G2 file.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our 3G2 converter.
