MKV

Matroska stores flexible media streams, including multiple tracks and subtitles.

Practical considerations

The v1 converter keeps primary video and audio only. Do not expect every track or subtitle to survive MP4 conversion.

Available tools

• MKV to MP4 — Convert the main video and audio streams to MP4.
• Compress video — Reduce resolution and file size for easier sharing.

Supported types and limits are specific to each tool. A familiar file extension does not guarantee that a malformed or protected file can be converted.
