Download Top Free MKV Splitter to Split MKV Averagely or by Time/Size
MKV is a multi-media container format, with multiple video tracks, audio tracks, subtitle tracks, etc. supported. Thus, it can provide you with higher crisp video image than most other formats. For this reason, the video file size in MKV format is also larger than those in other formats even though the parameters of video are the same.
Hence, if your MKV video footage is too large in size or long to a fault, the primary yet optimal option is to split MKV into several clips. Thus, you can reduce MKV video size or shorten MKV length without re-encoding, no quality degradation. To split MKV into small pieces, download a top free MKV splitter software first. Check the below top video splitter software if there is no candidate on your list yet.

Part 1. Top Free Online MKV Splitters to Split MKV in Your Browser
Free online MKV video splitter services are the primary options, since they can help you split MKV video into multiple segments in your browser, needless to download or install any 3rd party software or plug-ins. Considering its ease of use, we put them at the front position. Certainly, there are a wide selection of online MKV splitters available. It's out of the question to list all of them out. Instead, we pick up the most reliable services for you to conduct MKV splitting. Check them out:
- Highlight: 4 splitting methods offered: free splitting, average splitting, splitting by time, splitting by file size.
- Best for: users who have multiple needs on MKV video splitting (not only the average splitting) and enough patience.
- Room to optimize: reading file is taking seemingly forever, not only for MKV in 4K HEVC, but also in 1080p H264 codec.
The first time I choose a MKV 4K HEVC video (only 1.28 minutes) to this free MKV video splitter service and the reading file speed is good and slow. Maybe it's because of the ultra HD resolution and compute-intense codec HEVC, I guess. Therefore, I change the input MKV file into another one 1080p at H264 codec (2.47 minutes). But the situation doesn't turn any good. Thus, if you stick to its 4 splitting methods, you have to accept its demerit: snail speed.
Unsatisfactory speed is the biggest disadvantage of this free online MKV splitting service. It knows this and smartly uses video output format settings as a trade-off (beyond 4 splitting methods). It supports you to yield splitted fragments as MKV (kept as input), or MOV, MP4, AVI, 3GP, etc. 10 formats in total, with H264 or MPEG-4 codec to choose from. As for the elaboration of its highlight - 4 splitting workarounds, delve into them via the below step-by-step user guide:
How to online free split MKV into small pieces on split-video.com?
Step 1. Head to split-video.com, tap "Choose a file" or "drag file here" to import your desired MKV video file. Note: only sinlge MKV file is supported, MKV video folder excluded here.
Note: Be patient please. Unlike other video splitter software, this online tool reads your input MKV at unbelievably slow speed. As you can see, the progress bar shows the reading processing at 0.01% unit. No wonder some users complain that it takes forever to read video file.
Step 2. Choose splitting mode from the below 4 modes after your MKV video is successfully loaded. Directly try yourself or read the instructions before you go (if you don't want to waste time on meaningless trial).
Free Split: freely move the slidebar to decide your MKV clip length. Click "Add Split Point" to add more splitting lines if the default 2 points are not enough for you. As you can see, this splitting method allows you to split MKV at any duration, each clip not equally divided. This gives you maximum possible freedom in MKV splitting, both clip length and file size.
Average Split: its name has already explained itself clearly. The MKV file size and duration will be averagely divided into 2 segments (defaultly). Change the number of files if you need more than 2 segments.
Split by Time: time is your most significant standard to split MKV now. As you can see from the following picture, if you change the clips into 5, the duration of the first 4 clips keeps the same while the last clip gets the rest video length, unable to completely equally get splitted.
Split by File Size: similar to the afore-mentioned one, "split by file size" also can't guarantee you a 100% equally video splitting. If you change the file size at your willing, generally the last fragment only gets the rest file size, not your preset file size.
Step 3. Hit "Video output format settings" option to choose output video format, codec and audio codec. Still choose MKV as output format if you don't wanna change video format. But the video codec can't get 100% original if your input MKV codec is HEVC or AV1, cuz this free online MKV splitting website doesn't support other video codecs except for H264 and MPEG-4.
Step 4. Tap Split button (red button) to begin splitting MKV file online free. The notice coming later will again ask you to pay more patience since it's weak in splitting speed.
Providing you really can't bear the snail's space in MKV video splitting, resort to another online MKV splitter tool with faster speed.
- Highlight: Fast video reading and splitting speed.

Certainly, there is scarcely a man but has weak side. It's only versed in splitting MKV file by time, no size, average or free split. And it empowers you to manually split video. Thus, it's almost out of the question to precisely split MKV to equally segments with the same duration. If the mentioned aspects don't matter to you and you concern speed most, then follow the instruction to divide multi-track MKV now:

Step 4. Tap "Export" button after your multi-track MKV splitting is done. Export options window will pop up to let you make decision before exporting.
