How convert mkv to mp4 works
Process
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.
Good to know
MKV can contain multiple tracks, subtitles, or unusual codecs. This converter uses the primary video and audio tracks and does not preserve every attachment.
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.
