MKVToolnix for Windows 10 - Full description
MKVToolNix is an open-source toolkit for creating, inspecting and editing Matroska (MKV) video files. It is useful for video editors, media archivists and anyone who needs to combine tracks, examine file contents or adjust MKV metadata. The suite includes a graphical interface for common muxing tasks as well as command-line utilities for scripting and more precise control.
The central tool, mkvmerge, combines video, audio and subtitle sources into a single MKV file. In its GUI, users add source files, choose which tracks to include and set options such as track language and default playback status before starting the muxing job. This can bring separately stored audio, video and subtitles together without requiring them to be edited into a single stream first. Multiple sources and tracks can also be organized as part of one output file.
For inspecting and reusing existing content, mkvinfo displays a file's tracks, chapters, tags and other structural details. mkvextract can export selected elements, such as audio, subtitles or chapters, for separate editing or use elsewhere. These tools help users check what is contained in an MKV and retrieve only the components they need, rather than processing the entire file as one unit.
The suite also includes mkvpropedit, which changes selected properties of an existing MKV without remuxing the whole file. It can be used to edit track names, chapter information and metadata, making small organizational corrections more direct. The command-line versions of the tools suit repeatable workflows and batch operations, while the graphical interface offers an accessible way to configure and run muxing jobs without entering commands.
Typical uses include assembling a video with alternate audio and subtitle tracks, checking chapters and track details, extracting subtitles for translation, or correcting metadata before organizing a media library. MKVToolNix is free and open source. It is available for Windows 10 and Windows 11, including 32-bit and 64-bit Windows 10, and is also distributed for macOS and Linux. The command-line tools and GUI provide different ways to work with the same Matroska-focused operations.
