4 Common Free MKV Splitter

MKVToolnix - MKV Splitter for Windows and Mac


MKVToolnix is an open-source program that is specially designed for processing MKV files. Having 5 different split modes (After output size, After output duration, After specific timestamps, By parts based on timestamps, By parts based on frame/field numbers, After frame/field numbers, and Before chapters) is perhaps the best thing this MKV splitter freeware could give to you. With it, you can split TV show into single-episode files by chapters, and separate a big MKV file into a few smaller segments with social media friendly size, etc.

Unfortunately, it only supports the export of MKV files. And Its 80-style UI comes with lots of difficult jargon which made it is over-complicated for green hands. Currently, it is reported to meet incompatible issues when running on Mac high sierra machines.


  • Allow you to split MKV by size, duration, chapter, etc.
  • As an open-source MKV splitter, it's 100% free to use.
  • Run on the recent versions of Mac, Windows, and Linux.

2. VLC media player - MKV Splitter for Windows, Mac and Linux

VLC MKV Splitter Freeware
VLC media player

VLC media player is widely known for its high compatibility. It gives free access to millions of Mac, Windows, and Linux users to play videos and audio in both popular and rare formats. But did you know it can also be utilized as an MKV splitter freeware? I have to admit that VLC media player is the underdog on this list as it limits you to split MKV videos by recording the frames.

Unlike VideoProc Converter AI or other professional MKV splitter that allow splitting MKV in one go, VLC media player only lets you to manually split MKV by defining the duration for every single small file. However, if you're ready to invest plenty of time and take some exploration, VLC media player can still be helpful.


  • Free to use.
  • Split MKV by recording the playback.

LosslessCut - MKV Splitter for Windows, Mac and Linux

LosslessCut Free MKV Splitter

As you tell from the name, quality lossless splitting is the killer feature of this FFmpeg-based MKV splitter. It enables you to split MKV into multiple small pieces of files without re-encoding to ensure the after splitting video can retain the original quality. It has a well-designed interface that offers great ease for newbies fast splitting MKV, MP4, MOV, and other prevalent video files.

However, LosslessCut has ads, and it doesn't support to split videos automatically. You have to add multiple segments and then set the start and end time for each segment. However, this is not a big issue as it is definitely easier than VLC media player. Currently, it is not stable enough. Crashes and the output file won't play errors happen frequently.


  • Split MKV by setting up the start and end time of each clip.
  • Cut and split video by either Keyframe cut mode or Normal cut mode.
  • Turn MKV to MOV, MP4, and a few other formats.
  • Quality lossless and fast response.

BeeCut - Online MKV Splitter

BeeCut MKV Splitter

BeeCut is the only online MKV splitter on this list. This is a multifunction video editing toolset released by Apowersoft, allowing you to split the MKV file into multiple small parts without installing an extra software. All you have to is feeding it the source clips, set the duration (start/end time) for each output clips, and then click on Done. Sadly, as a web-based MKV splitter, it has some non-ignorable drawbacks, for instance, slow loading speed, high reliance on the network environment. These made BeeCut barely impossible to be useful for splitting big MKV videos.


  • Split MKV file into many mall parts online.
