MOV to 3G2 Converter

Convert MOV to 3G2 Online

3G2 is the small, legacy 3GPP2 container built for CDMA2000 phones, so this tool re-encodes your Apple QuickTime MOV into 3G2 and usually downscales it to a low resolution. That trade is the whole point: a tiny clip an old CDMA handset can play, or a file that squeezes under a strict size cap — not a higher-quality copy. If your target phone is on a GSM carrier, use MOV to 3GP instead; if you just want a modern, full-resolution file, convert to MP4.

How to Convert MOV to 3G2

1. Upload Your MOV File: Drag and drop your .mov onto the page or click "Add Files." You can queue several clips and convert them with the same settings.
2. Pick a Quality Preset: Open Advanced Options and choose a Quality Preset, or set a Specific file size if you have a hard size cap to hit. The default output uses H.264 video with AMR audio inside the 3G2 container.
3. Set the Video resolution (optional): Under Video resolution, choose a Preset Resolution like 240p or 176x144 for genuine feature-phone compatibility, or keep a larger size for a newer device. You can also Trim a Time Range to shorten the clip before encoding.
4. Convert and Download: Click Convert and download your 3G2 file. No sign-up, no watermark.

Frequently Asked Questions

What is the difference between 3G2 and 3GP?

Both are mobile containers derived from the MP4 / ISO base media file format and share the same video codecs (H.263, MPEG-4 Part 2, H.264). The split is the network: 3GP (.3gp) is defined by the 3GPP for GSM/UMTS phones, while 3G2 (.3g2) is defined by 3GPP2 for CDMA2000 phones. The practical difference is audio — the 3G2 format can additionally carry CDMA-specific speech codecs such as EVRC and 13K (QCELP) that 3GP does not. If your handset is on a GSM carrier, convert MOV to 3GP instead.

Which codecs does the 3G2 output use?

In Advanced Options you can pick the video codec from H.263, H.263+, H.264, MPEG-4 (Part 2), and Xvid, and the audio codec from AAC, AMR Narrow Band, and AMR Wide Band. By default we output H.264 video with AMR audio, which most 3G2 players accept. For the oldest handsets, H.263 paired with AMR-NB is the most universally compatible combination. The QCELP and EVRC speech codecs are part of the 3G2 specification but are not offered as encode options here.

Will converting MOV to 3G2 reduce the video quality?

Yes — expect lower quality, by design. 3G2 was engineered for CDMA-era mobile playback at very low bitrates, so it pairs older codecs with low resolutions. Re-encoding a modern MOV into 3G2 re-compresses the picture and usually downscales it. In our testing, a short 1080p MOV downscaled to a 176x144 3G2 at default settings produced a file a small fraction of the original size, which is exactly why people reach for this format. If you need to keep full detail, convert MOV to MP4 instead.

Why would anyone still use 3G2 in 2026?

Rarely, and only for specific reasons: playing a clip on a very old CDMA handset, feeding legacy hardware or software that only accepts 3G2, or producing the smallest possible file for a strict size or bandwidth limit. Most CDMA networks have been retired, so for everyday sharing or any modern phone, MP4 is the better target.

Is my file kept private during conversion?

Yes. Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after the conversion finishes — no sign-up, no watermark, and it is never shared or made public. The main real-world limit on a big MOV is upload size and time, not the conversion itself; trimming the clip first or targeting a Specific file size keeps the job fast.
