Why Convert 3G2 to 3GP?
3G2 and 3GP are nearly identical mobile video formats with one key difference: 3G2 was created for CDMA networks (Verizon, Sprint), while 3GP targets GSM networks used worldwide. If your device or software only accepts 3GP, converting from 3G2 preserves video quality while switching to the more widely compatible container. 3GP has broader support across mobile devices, media players, and video editing software globally.

Use Cases
- GSM device compatibility — Convert CDMA phone recordings to 3GP for playback on GSM-based phones and devices worldwide.
- Software compatibility — Some video editors and media players accept 3GP but not 3G2. Convert for broader software support.
- MMS sharing — 3GP is the more widely accepted format for MMS video messages across global carriers.
- Archival standardization — Consolidate a mixed collection of 3G2 and 3GP files into a single format.
What is the difference between 3G2 and 3GP?
3G2 was designed for CDMA networks (Verizon, Sprint) and supports EVRC and QCELP audio codecs. 3GP was designed for GSM networks (used worldwide) and focuses on AMR and AAC audio. Both support the same video codecs and produce identical visual quality.
Will converting 3G2 to 3GP lose quality?
With the "Very High" Quality Preset, the output is visually indistinguishable from the source. Both formats support the same video codecs, so quality preservation is excellent.
Does this accept 3GP files too?
Yes. The converter accepts both 3G2 and 3GP files as input.
Can I trim the video during conversion?
Yes. Use the Trim option to set a start time and duration. Only the selected segment is converted.
Which format has better compatibility?
3GP has broader global compatibility since GSM is the dominant mobile standard worldwide. 3G2 is primarily used in the US on CDMA networks.
