How to convert MKV to MP4 online
Open a Matroska MKV file and export an MP4. Most MKV files hold H.264 or HEVC video with AAC audio, which the MKV to MP4 converter copies into MP4 without re-encoding, so large files finish quickly and keep their quality.

What to expect
- Supported inputs
- MKV videos and other readable video files.
- What happens
- Tracks MP4 can hold are copied unchanged. Dolby Digital audio is re-encoded so browsers can play the MP4, and other incompatible tracks are re-encoded or left out.
- Limits
- Subtitle tracks are not carried into the MP4. Tracks that need re-encoding depend on this browser's encoders and take longer.
Your files stay on your device
Your computer does the work, so the file never has to be uploaded, and that’s also why it’s free: there’s no server time for us to pay for. You don’t need an account, and nothing you make gets a watermark.

Questions
Not when the tracks are copied. H.264, HEVC, and AAC move into MP4 unchanged; only tracks MP4 or browsers can't play are re-encoded.
Yes. MP4 can hold more than one audio track, so each language is copied. Subtitle tracks are left out.
