Supports: 3GP, 3G2
3G2 (3GPP2) is a mobile video format developed for CDMA-based phones (Verizon, Sprint, US Cellular in the 2000s–2010s). These files use H.263 or MPEG-4 video at low resolutions (176×144 to 352×288) with AMR audio. While 3G2 was designed for efficient mobile streaming on 2G/3G networks, it's poorly supported on modern devices and desktop software.
MPEG is the universal video standard — playable on virtually every device, media player, and operating system. Converting 3G2 to MPEG rescues old mobile phone videos (text message clips, early camera phone recordings) and makes them viewable on modern computers, smart TVs, and media players. This is especially valuable for preserving personal memories from the flip phone era.

| Player support | Limited | Universal |
| Quality | Low (mobile-optimized) | Standard to high |
| File size | Very small | Moderate |
3G2 was used by CDMA mobile phones from Verizon, Sprint, and US Cellular — brands like LG, Samsung, Motorola, and Sanyo flip phones and early smartphones from roughly 2003–2015. These phones recorded video at very low resolutions for MMS messaging.
Converting doesn't add detail that wasn't in the original. 3G2 files are typically very low resolution (176×144 or 352×288). The conversion makes them playable on modern devices, but the visual quality remains limited by the original recording.
Since 3G2 files are already very small and low-quality, use "Quality Preset: Very High" or "Highest" to preserve as much detail as possible. Aggressive compression on already-compressed low-resolution video would degrade quality further.
Yes. This tool accepts both 3G2 and 3GP files — they're closely related formats from the 3GPP and 3GPP2 standards respectively.
For modern use, 3G2 to MP4 is usually better — MP4 is more widely supported on web, mobile, and streaming platforms. MPEG is ideal for DVD authoring or legacy media player compatibility.
