3GP to WEBM Converter

Convert 3GP files to WEBM. Free, without uploading.

This tool converts 3GP files to WEBM. Legacy mobile phone video.

WEBM is an open video format built for the web (VP8/VP9 video, Opus audio). Browsers play it natively. The video is re-encoded with VP8 video and Opus 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 3GP video, drag it in, or paste its link.
2. Choose the quality and resolution; optionally enter trim times.
3. Press "Convert" and download the WEBM file.
