3G2 to MKV Converter

Convert 3G2 files to MKV. Free, without uploading.

This tool converts 3G2 files to MKV. Legacy mobile video (CDMA).

MKV (Matroska) is a flexible container that can hold several audio and subtitle tracks. It is common on computers, but phones and TVs don’t always play it. The video is re-encoded with H.264 video and AAC audio. You choose the quality and resolution, and can trim it with a start and end time.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the 3G2 video, drag it in, or paste its link.
2. Choose the quality and resolution; optionally enter trim times.
3. Press "Convert" and download the MKV file.
