DivX to 3GP Converter

Convert DivX to 3GP Online

DivX is an MPEG-4 Part 2 (Advanced Simple Profile) video codec, usually wrapped in an AVI file with MP3 audio. 3GP is the small, low-resolution 3GPP container built for older feature phones and MMS video, typically carrying H.263 or MPEG-4 video with AMR audio. This converter re-encodes a DivX clip into a compact 3GP so a legacy handset or a messaging gateway that only accepts 3GP can play it. If your target device is a modern smartphone, convert DivX to MP4 instead — every current phone plays MP4, and you avoid the resolution and quality loss 3GP forces on you.

How to Convert DivX to 3GP

1. Upload Your DivX File: Drag and drop your .divx or .avi file onto the page, or click "+ Add Files" to browse. You can queue several clips and convert them with the same settings.
2. Set Quality Preset and Resolution: Open Advanced Options and pick a Quality Preset (Very High is the default; drop to Medium or Low to shrink the file), then use Preset Resolutions or Width x Height to downscale — 176x144 (QCIF) or 352x288 (CIF) match what most 3GP-era phones expect.
3. Trim if You Only Need a Clip (Optional): Use the Trim control to set a start time and duration so an MMS-bound clip stays under the carrier's size and length cap.
4. Convert and Download: Click "Convert" and download your 3GP file. No sign-up, no watermark.

DivX vs 3GP at a Glance

Frequently Asked Questions

Will converting DivX to 3GP reduce the video quality?

Yes. This is a re-encode, so it adds a generation of compression loss, and 3GP is a low-resolution format — you almost always have to downscale. Expect a noticeably softer picture than the DivX source. That trade is the point of 3GP (tiny files for old phones); if you don't specifically need 3GP, keep more quality by going to MP4.

Should I convert DivX to MP4 or to 3GP?

Choose 3GP only when a particular old feature phone, a car head unit, or an MMS/messaging gateway refuses anything else. For any phone made in roughly the last decade, DivX to MP4 is the better choice: similar small files, far better quality, and universal playback. 3GP is essentially a legacy-compatibility format today.

What video and audio codecs does the 3GP output use?

The 3GP container carries H.263 or MPEG-4 video with AMR or AAC audio, which is what older 3GPP-compliant phones expect. You can adjust the codec and resolution in Advanced Options if a specific device needs a particular combination, but the defaults target broad legacy-handset compatibility.

Why is my 3GP file so much smaller than the DivX original?

3GP is engineered for low bandwidth and small screens, so it uses lower resolution, lower bitrate, and narrowband audio. A multi-megabyte DivX clip can become a few hundred kilobytes as 3GP — convenient for MMS and limited storage, but with a visible drop in sharpness.

How small can I make the file for an MMS message?

Use the Trim control to keep the clip short, downscale to 176x144, and pick a lower Quality Preset. In our testing, a 30-second 480p DivX clip downscaled to QCIF at the Low preset produced a 3GP file under 300 KB, well within typical MMS limits. Carrier caps vary, so check your provider's limit if the message won't send.

Are my files kept private during conversion?

Yes. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and your files are never shared or made public.

Can I convert the 3GP back to a standard format later?

Yes, but you can't recover the detail lost in the downscale. If you later need a modern format, run 3GP to MP4; it will rewrap and re-encode to MP4, though the result is only as sharp as the 3GP you feed it. Keep your original DivX file if you want a high-quality master.
