How to convert 3GP to 3G2
- Add your .3GP file - drop it in the box above or click to browse.
- Convert it to .3G2 in a few seconds.
- Download your new .3G2 file.
What to expect
- Both formats use the same container structure; only the file-type brand string in the header differs, so remuxing is instant and lossless.
- AMR audio found in many 3GP files may not play on strict 3G2 devices - re-encoding to AAC fixes this but slightly reduces audio quality.
- 3GP and 3G2 are both legacy formats; if you need modern compatibility, converting to
.mp4offers far broader support.
Frequently asked questions
Will converting 3GP to 3G2 lose video quality?
No - remuxing copies the compressed video frames unchanged into a new container, so there is no quality loss on the video track.
Is 3G2 the same as 3GP?
They are close siblings sharing the same container structure; 3GP targeted GSM networks and 3G2 targeted CDMA networks, differing mainly in supported codec profiles and the brand string in the file header.
Why does the converted file have no audio or broken audio?
The source 3GP likely uses AMR audio, which some 3G2 devices reject; re-encoding the audio track to AAC - for example with FFmpeg's
-c:a aac flag - fixes the problem.Can VLC play both 3GP and 3G2 without converting?
Yes - if your only goal is playback, VLC handles both formats on Windows, macOS, and Linux with no conversion required.
