About the 3G2 file format
3GPP2 Multimedia (3G2) is a video format from which mp3.now can extract an audio track and convert it to MP3.
The guide and converter lists are generated from the live MP3.now catalog, so every conversion shown here is available.
Why 3G2 files are used
3GPP2 Multimedia files combine video, audio, timing and metadata in the .3g2 format.
On mp3.now, 3G2 is used as a source when you want to extract its audio track into a standalone MP3 file.
What to know about 3G2
Media container
3G2 can hold encoded video and one or more audio tracks.
Audio extraction
Conversion to MP3 keeps the selected audio content and removes the video stream.
Codec support
Successful decoding depends on the codecs stored inside the container.
File size
Video sources are usually much larger than the extracted audio result.
How 3G2 conversion works
Converting 3G2 decodes the source audio and encodes it with the destination format's codec and selected quality settings.
Lossy conversion cannot restore detail already removed from the source, so keep the original when quality matters.
mp3.now accepts 3G2 as an input and converts its audio to MP3.
3G2 compatibility and software support
Playback support for 3G2 depends on the device, browser, container features and codecs inside the file.
MP3 output is broadly supported by phones, computers, browsers, editors and media players.
