## How it works

Choose an MP4 file and start the conversion. The video is encoded with VP8 and the audio is encoded with Opus at a compatible sample rate.

## Result

A WebM file designed for modern browser playback and HTML video use.

## Limitations

WebM conversion re-encodes the media. Processing time increases with duration and resolution, and output quality depends on the source.
