This tool converts MKV to M4V completely free and without any functional limitations. Since it is based on the browser API, the processing speed is the fastest because all files are processed locally on your device and are not uploaded to our server.
Batch Convert MKV to M4V Online
With this convertor, you can easily convert multiple MKV files to M4V format directly in your browser — completely free. You can also customize the video resolution (width and height) during the conversion.
To access advanced settings, click the Options button in the top right corner. There, you can set the output size for your M4V files.
Additional Settings:
Video Size: Set the width and height for the output M4V file.
Encoding Speed:Controls how fast the video is encoded. Faster speeds may result in larger file sizes.
Video Bitrate:Set between 1–10,000 Kbps to control the video quality and file size.
Frame Rate:Defines the video’s FPS (frames per second). Higher frame rates produce larger files.
Audio Bitrate:Recommended range is 16–320 Kbps.
Cut Video: Trim the video using a start and end time in HH:MM:SS format.
For example, setting 00:00:05 to 00:00:08 will cut a 3-second clip from the video or animation.
Before converting, you can choose a folder on your device where the converted M4V files will be saved. Each MKV file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.
Save All: Once all MKV files are converted, click
Save All to instantly save all M4V files to your selected folder.
About MKV files
MKV (Matroska Video) is a flexible, open-source multimedia container that stores video, audio, subtitles, and metadata in a single file. It supports advanced features like multiple audio tracks, chapters, and modern video codecs such as H.265/HEVC. Widely used for HD movies, TV shows, and streaming, MKV is compatible with players like VLC. We can also convert MKV files to animated formats such as GIF, WebP, and APNG.
About M4V files
M4V is a digital video format developed by Apple, based on the MPEG-4 standard. It is commonly used for storing movies and TV shows, especially those purchased or rented from iTunes. Like MP4, M4V supports high-quality video and audio compression, but it may include DRM (Digital Rights Management) protection to restrict unauthorized copying. M4V files can be played on Apple devices like iPhone, iPad, and Mac, as well as some other players that support the format. Its compatibility depends on whether DRM is applied.
