MOV to 3GP Converter

Convert MOV to 3GP Online

3GP is the small, legacy 3GPP mobile container built for old feature phones and MMS — so this tool re-encodes your Apple QuickTime MOV into 3GP and usually downscales it to a low resolution. That is the point: a tiny file an old handset can play or that squeezes under a strict upload cap, not a higher-quality copy. If you instead want a modern, full-resolution file, convert to MP4 rather than 3GP.

How to Convert MOV to 3GP

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 upload cap to hit. The default output uses H.264 video with AMR audio inside the 3GP container.
3. Set the Video resolution (optional): Under Video resolution, pick a Preset Resolution like 240p or 176x144 for genuine feature-phone compatibility, or keep a larger size if your target device is newer. You can also Trim a Time Range to shorten the clip first.
4. Convert and Download: Click Convert and download your 3GP file. No sign-up, no watermark.

MOV vs 3GP at a Glance

Frequently Asked Questions

Will converting MOV to 3GP reduce the video quality?

Yes, expect lower quality. 3GP was engineered for 3G-era mobile playback, so it pairs older codecs (H.263 or MPEG-4 Part 2) with low resolutions. Re-encoding a modern MOV into 3GP re-compresses the picture and usually downscales it. You are trading visible detail for a much smaller file that legacy hardware can handle — if you want to keep the original quality, convert MOV to MP4 instead.

Which codecs does the 3GP output use?

In the Advanced Options you can choose the video codec from H.263, H.263+, H.264, MPEG-4 (Part 2), and Xvid, and the audio codec from AMR Narrow Band, AMR Wide Band, and AAC. By default we output H.264 video with AMR audio, which gives broad 3GP player support. For the oldest handsets, H.263 with AMR-NB is the most universally compatible pairing.

What is the difference between 3GP and 3G2?

Both are mobile multimedia containers derived from the MP4/ISO base media file format, but 3GP (.3gp) is defined by the 3GPP for GSM/UMTS phones, while 3G2 (.3g2) is defined by 3GPP2 for CDMA2000 phones. They share the same video codecs; 3G2 differs mainly in its audio support (it can carry CDMA-specific speech codecs like QCELP/EVRC). If your target device is on a CDMA carrier, convert MOV to 3G2 instead.

Why would anyone still use 3GP in 2026?

The honest answer is rarely — MP4 has replaced it almost everywhere. The remaining reasons are specific: playing video on a very old feature phone, feeding legacy hardware or software that only accepts 3GP, or producing the smallest possible clip for a strict size or bandwidth limit. For everyday sharing or modern phones, MP4 is the better choice.

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. In our testing, a short 1080p MOV downscaled to a 176x144 3GP at default settings produced a file a fraction of the original size, which is exactly why people reach for this format.

Can I get the quality back by converting the 3GP back to MP4 later?

No. Downscaling and re-encoding to 3GP permanently discards detail, so converting 3GP back to MP4 only rewraps the existing low-resolution video — it cannot recover what was thrown away. Keep your original MOV if you may need full quality again.
