Convert MKV to MP4 for More Compatibility with Devices and Platforms

As MKV files are not fully compatible with all streaming sites (YouTube, Netflix, or Hulu), game consoles (PlayStation and Xbox), streaming devices (Chromecast and Apple TV), and some old TVs and DVD players, you need to convert MKV to MP4 to ensure the best compatibility with more devices, video players, and video editing software.

Any Video Converter utilizes the advanced encoding technology to ensure more efficient MKV to MP4 conversion, 60X faster and best quality.

Convert MKV to MP4 for Free to Reduce the Large File into a Smaller One

MKV files are typically larger in file size, due to the less efficient codecs like XviD or DivX, and multiple video or audio tracks, and subtitles contained.

To compress the MKV file to reduce the size without losing quality, you can convert MKV to MP4 with more efficient codecs like H264, H265, and AV1. For more efficient conversion, you can also use the built-in track editor to remove unnecessary tracks and subtitles.

Tips: Try our dedicated video compressor to compress MKV videos with higher efficiency.

Auto Trim MKV File into Clips and Convert them to MP4

Trimming MKV video and converting it to MP4 can help smooth and simplify your video editing process, focusing on a shorter clip rather than a large, untrimmed MKV video.

Trim MKV: Trim to remove your unwanted or unnecessary part (audio and video are out of sync) from the MKV video, and convert the remaining part to MP4 to reduce the file size and improve the video editing efficiency.

Split MKV: The auto-trim algorithm can analyze the scene changes and transitions, then automatically split the MKV video into multiple segments for the convenience of extracting specific clips for further editing or direct exporting.

Track Editor for MKV: Extract or Remove Video and Audio Tracks, and Subtitles

MKV is a kind of container that can hold multiple video tracks, audio tracks, and subtitles. With the track editor tool of this MKV to MP4, you can delete the unnecessary tracks and subtitles from the MKV video, thus compressing the video size and improving the MKV to MP4 conversion efficiency.

It also supports extracting and exporting the audio tracks and subtitles from MKV, whether using them for another video clip or for more flexible further video editing.
