MKVToolNix 32-bit is a set of tools to create, alter, and inspect Matroska files under Linux and Windows. They do for Matroska what the OGMtools do for the OGM format and then some.

It features support for treating several input files as if they had been concatenated binarily into a single big input file.

MKVToolNix is a set of software tools that include mkvmerge, mkvinfo, mkvextract, mkvpropedit, mmg, and others.

How to Use

Install the software using the setup wizard

Launch MKVToolNix 32bit GUI from the start menu

Drag and drop MKV or other input files into the GUI

Select or deselect tracks, subtitles, and audio streams

Choose the output folder and file name

Click "Start multiplexing" to begin processing

Wait for the task to complete and check the output file

Alternatives

HandBrake – Better for video conversion and compression.

What's new in this version:

New features and enhancements:
- MKVToolNix GUI: the GUI will now remember the last used directory for selecting audio files for playback in “play audio file” program runners separately from any other “open file”-type situations. This directory will also default to /System/Library/Sounds on macOS now.

MKVToolNix GUI: executing actions → running programs: added new variables: MTX_DESTINATION_FILE_BASE_NAME (the name without the drive letter, path or the suffix; e.b. /movies/A.new.hope.mkv → A.new.hope) and MTX_DESTINATION_FILE_SUFFIX (only the letters after the last ., e.g. /movies/A.new.hope.mkv → mkv). Added examples to all the destination file variables in the popup menu when adding variables in the preferences
- MKVToolNix GUI: executing actions → running programs: the command-line input widget will now receive focus again after using the popup menu for adding a variable
- MKVToolNix GUI: executing actions → running programs: the variables will now also be set as environment variables when running a program after a job completes.
- MKVToolNix GUI: executing actions → running programs: when using the “Execute now” button for testing the MTX_… variables will be set to the current multiplexer tab’s values for easier testing

Fixed:
- mkvmerge: if using legacy font MIME types is off mkvmerge will now remap legacy font MIME types present in source files into the current ones
- mkvmerge, mkvpropedit, MKVToolNix GUI’s multiplexer & header editor: on Windows & macOS the MIME type detection will now use the FreeDesktop.org MIME database instead of falling back to file extension-based guesses. This matches how it works on other operating systems. This fixes e.g. OpenType fonts being detected as the legacy type application/vnd.ms-opentype instead of the current IETF RFC, font/otf, no matter what the “use legacy font MIME types” settings in the preferences was set to.
- MKVToolNix GUI: update checker: fixed a potential attempt to read from an invalid memory address if an error occurred when parsing the XML file retrieved from the official MKVToolNix server
- macOS: GUI: the default audio file for program runners of type “play audio file” has been changed to an AIFF file as Qt’s Multimedia backend routes through Core Audio which doesn’t support WebM/VP8/Vorbis/Opus. Existing configurations will be updated if they point to the prior default WebM audio file.
