What is 3G2 to MP4 conversion?

3GPP2 (3G2) and MPEG-4 (MP4) are two popular video containers, but not every player or editor handles them all. This free converter reads your .3g2 file, decodes its streams and re-encodes them into a valid .mp4 file with widely supported codecs. The whole conversion runs in your browser, so your video stays private.

How it works

1Upload a .3g2 video file.
2Choose MP4 from the output format menu.
