Canonical URL: https://soulnio.com/mkv-to-mp4

## How it works

Choose an MKV file and start the conversion. The first video and audio tracks are encoded for the MP4 container.

## Result

An MP4 with H.264 video and AAC audio for broad support in browsers, phones, editors, and presentation software.

## Limitations

MKV can contain multiple tracks, subtitles, or unusual codecs. This converter uses the primary video and audio tracks and does not preserve every attachment.

## Frequently asked questions

### Will subtitles be included?

No. The current MP4 output converts the main video and audio tracks only.

### Why does conversion take time?

The source codecs are decoded and re-encoded for reliable MP4 playback.
