MKVtools is a collection of tools used to manipulate video files. It's primary purpose is to convert mkv files into more user friendly formats for playback on a variety of hardware. MKVtools is trialware - only $4.99 for full functionality, though it will function unregistered, with some minor limitations.


  • Convert videos to either .avi files or .mp4 files.
  • Extract the selected .mkv tracks as individual video, audio and/or subtitle files.
  • Intuitively select desired video, audio and/or subtitle tracks to procces, with the ability to verify the selections using video more...

What's New

Version 3.4.2:
  • Fixed bug that could cause some 2-pass conversions to fail.
  • Fixed a bug that could cause the app to crash during track extractions.
  • Fixed a bug that could prevent conversions from working properly after track extraction jobs.


  • OS X 10.7 or later

An application I need and would love to like. Unfortunately it is very buggy, and the frequent updates do not solve its shortcomings. A simple muxing this evening to add subtitles to a couple of HD movies with video and audio Pass Thru took 20 minutes on my rMBP to complete. It took MkvToolnix exactly 12 seconds.

So far, this app has not worked out for me. My needs include taking MKVs that are too large and converting them to better compression and lower resolution. Each time, MKVT pulled the audio/video out of sync... even when I test a complete pass through without changing the output from the input. That's not a good sign.

While I appreciate that the program provides a clean interface that still offers enough tweaking for basic needs, if it cannot accurately do an MKV to MKV transcode, I will return to Handbrake (which is free, though convoluted, and does the job right in all cases).

It's a very good and useful tool but as I try to include soft subtitles in portuguese to a m4v file (or mkv) and convert back to mkv I can't change the .srt subs charset to ISO-8859 or haven't seen an option there to do ti. Without that my subtitles don't show correctly on the converted mkv video. I did the job with MKVtoolnix and went fine though, this one is a great tool to, so far, and for me, is less confusing than MKVtools. I'll keep both in my video arsenal.

Just downloaded a movie with subtitles I did not want.
With this programme I removed them. So easy.
Highly recommended.
Also I have a media player which although plays mkv files ok
will not fast forward or backwards.
But converting them to mp4 and no loss of quality, I can then fast forward and back with no problems.
Well worth the $4.99
Now all I want is to convert to mpg for my DVD.

For those who do deal with .mkv files, this is very good app. I already own Aimersoft Video Conveter (which costs $35) - but this would be perfect for those who just want a simple, specific converter (VLC Player will play .mkv files).

I do not recommend converting to .avi files - .mp4 is much more Mac friendly.

This would be perfect if it could burn in SSA/ASS subtitles and keep the positioning and font colours.

I LOVE MKVtools! The one thing that would make me love it even more would be the ability to mux the streams that I demux out of Matroska files into MPEG2 (program stream) or .mpg files (or anything else that can then be quickly processed into a DVD without re-encoding, if that's possible).

Developer, a quick note: MKVtools 2.4.4's Get Info still says it's Universal instead of the pure Intel Must-Have App it has become.

Also, every single time I select an existing destination folder for whatever operation I'm doing with MKVtools I get an annoying error (something about 'syntax' problems), so I ALWAYS have to create a new output folder.

Download link STILL non-functional.

Version 2.4.2

I now have the download link pointing to the 'Download Page' on the developer's site; about halfway down the page, you should see the download link. I'm trying to find a way to link the file more directly, as the developer's site doesn't seem to allow direct linking.

Sorry for the inconvenience.

This tool works great. I used it to convert a BD rip to a Mac-friendly video format and MKVtools performed flawlessly.


I refuse to go through an obnoxious license structure for a $5 app. And tying it to a single computer is so 1990's. I've got four computers, but I use at least two everyday (MacBook Pro and Mac Pro) and it's only fair I can use it on at least two. Charge $10 if needed, I'd pay that.

Also, because of the work I do, I'm frequently upgrading hardware and I'd have to purchase this and re-license *every* time.

Thanks, but no thanks.
