Create, alter, and inspect Matroska (mkv) files.

Overview

MKVtoolnix is a set of tools to create, alter, and inspect Matroska files under OS X, Linux and other Unices, and Windows. They do for Matroska what the OGMtools do for the OGM format and then some.

Since May 1st 2003, the Matroska libraries themselves and my Matroska tools are officially released as a first public beta version. Although all of them are still under heavy development, I urge you to download the software, test it and report any errors you encounter to me. I'm always grateful for good bug reports because I miss so many mistakes and you guys normally find them. Your feedback is important to me :)

Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.

What's new in MKVtoolnix

Version 40.0.0:
New features and enhancements
  • Mkvmerge: MP4 reader: added support for BMP covert art images.
  • MKVToolNix GUI: multiplexer: added an option to disable deriving the destination file name from the file title. Implements #2648.
  • MKVToolNix GUI: multiplexer: the content of the "stereoscopy" combo box has been simplified making the box's minimum width much smaller, allowing the user to resize the GUI's whole window to a much smaller width.
  • MKVToolNix GUI: multiplexer: whenever the user changes the "aspect ratio" or "display dimensions" controls, the corresponding radio button will be activated automatically. Implements #2651.
  • MKVToolNix GUI: Windows: added a setting in the preferences to disable the GUI's dark color mode even if Windows's app color mode is set to dark. Implements #2646.
  • MKVToolNix GUI: Windows: replaced the dark mode introduced in v39 with another dark mode that's less wasteful with space between widgets.

Doesn't start on 10.11 here (no crash on startup). The application is about 20 MB smaller than 29.0.0 and that sounds strange.

30.1.0 released but it requires Sierra, as most likely did 30.0.0, even though the Info.plist in package contents still lists Mavericks as minimum requirement.

Great app for complete control of MKV files. Will you be releasing a "Dark" version for Mojave?

Very good app. I would give all the stars if "Stretch by" would work on audio.

READ THIS: initial release of 9.7.1 would only launch on 10.12 Sierra due to inadvertent compiler setting. A new build, #4, is now available as of Dec 30 which runs on 10.9 and later. Download direct here (don't download from MacUpdate link): https://www.fosshub.com/MKVToolNix.html/MKVToolNix-9.7.1-build4.dmg If you're not sure what build you have, or if you get an error at launch about needing 10.12 or later to run, just make sure you get build #4. 5 stars for the developer Moritz for working it through and resolving it.
