MKVToolNix is a free, open-source set of tools for working with Matroska (MKV) video containers on macOS and other platforms. It includes a GUI application that lets you create, edit, and remux MKV files — combining video, audio, and subtitle tracks from multiple sources, adding or removing streams, setting default tracks, adding chapters and metadata, and adjusting properties like aspect ratio and audio synchronisation. It is widely used by video enthusiasts and archivists who need to work with MKV files without re-encoding the video or audio, as well as by anyone managing video libraries with complex audio and subtitle tracks. The tool includes both a graphical interface (MKVToolNix GUI) and command-line utilities for batch processing.
AI Recommendation
1 suggestionA native Apple Silicon build of MKVToolNix has been confirmed running on real Macs in the Rosetta Check community. If you are still running an older Intel-only build under Rosetta, updating to the latest version will give you noticeably better performance and lower CPU usage during remuxing operations. Download the latest build directly from the MKVToolNix website, where the macOS installer is available for both Intel and Apple Silicon architectures. The installation and your existing settings will carry over without issues.
