3GP to 3G2 Converter

3GP to 3G2 Converter

3GP and 3G2 are sibling mobile-video containers from the early-3G era: .3gp is the 3GPP format used on GSM/UMTS handsets, while .3g2 is the 3GPP2 variant built for CDMA2000 networks (the older Verizon- and Sprint-era CDMA phones). Both are built on the same ISO base media file format, so converting between them is largely a re-container plus a codec normalization — useful when a specific CDMA handset, MMS gateway, or legacy app insists on the .3g2 extension. This tool uploads your file over an encrypted connection, transcodes it on our servers, and lets you download the .3g2 result with no sign-up and no watermark.

The key practical difference: 3G2 adds CDMA-specific speech codecs (QCELP, EVRC, SMV, VMR-WB) but drops 3GP's HE-AAC v2 and AMR-WB+ audio. For the video stream, the two are essentially interchangeable. Our converter defaults the output to H.264 video with AMR audio, which both families accept.

How to Convert 3GP to 3G2

1. Upload Your 3GP File: Drag and drop your .3gp file onto the page or click "Add Files." You can queue several clips and convert them with the same settings.
2. Set Video and Audio Codec: Open Advanced Options to choose the Video Codec (H.264, H.263, MPEG-4, or Xvid) and Audio Codec (AMR Narrow Band, AMR Wide Band, or AAC); the default H.264 + AMR pairing plays on the widest range of 3G2 handsets.
3. Adjust Resolution or Trim (Optional): Use Video resolution / Preset Resolutions to downscale for an old screen, or Trim with a Time Range to keep only part of the clip.
4. Convert and Download: Click Convert and save your .3g2 file. No sign-up, no watermark.

Frequently Asked Questions

Is converting 3GP to 3G2 worth it, or should I just use MP4?

For any modern device, MP4 (H.264) is smaller, universally supported, and the better target — see Convert 3GP to MP4. Convert to 3G2 only when a specific CDMA handset, carrier gateway, or legacy application refuses anything but the .3g2 extension. Re-encoding cannot add detail to an already low-resolution mobile clip.

Will I lose quality going from 3GP to 3G2?

The video stays in the same H.264/H.263/MPEG-4 family both formats share, so a straight re-container keeps the picture intact. Any visible loss comes from re-encoding the audio into a 3G2-friendly codec (AMR or AAC) and from the fact that the source was already a compressed, low-bitrate mobile recording.

What audio codecs does 3G2 support that 3GP doesn't?

3G2 adds the CDMA2000 speech codecs QCELP (13K), EVRC, EVRC-B, EVRC-WB, SMV and VMR-WB. In exchange, it omits HE-AAC v2 and AMR-WB+, which 3GP allows. For broad compatibility our converter outputs AMR or AAC, which both formats accept.

What program opens a 3G2 file once I've converted it?

VLC Media Player plays .3g2 (and .3gp) on Windows, macOS, and Linux without extra codecs. QuickTime opens it on macOS, and Windows Media Player handles most 3G2 files on Windows. On the originating CDMA handset it plays through the built-in media app.

Are 3GP and 3G2 really the same format?

They are siblings, not identical. Both derive from MPEG-4 Part 12 (the ISO base media file format) and share their video codecs, which is why conversion is mostly a re-container. They diverge on audio support and on the standards body and network each was designed for: 3GPP/UMTS for 3GP, 3GPP2/CDMA2000 for 3G2. If you need the reverse, use Convert 3G2 to 3GP.

Is the file kept private during conversion?

Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. It is never shared, made public, or used for anything but your conversion — no sign-up and no watermark. In our testing, a short 176x144 .3gp clip converts to .3g2 in a few seconds.
