MKVToolnix

Free Manager for MKV Files

MKVToolNix is a free MKV manager that allows you to create, edit, and view MKV files through a graphical user interface. This open-source software, developed by Moritz Bunkus, enables modifications using the C++ programming language. The MKVToolNix GUI is cross-platform, supporting Apple Mac, Linux, Microsoft Windows PC, and other Unix 32-bit and 64-bit operating systems.

An MKV file, also known as a Matroska file, is a digital container for multimedia content, capable of storing audio, video, and text. MKV files are popular due to their ability to package multiple media types. With MKVToolNix, you can manage various elements within the MKV container, such as headers, subtitles, and visuals.

What is an MKV File? What Does MKVToolNix Do?

MKVToolNix provides tools like mkvextract, mkvinfo, mkvmerge, mkvpropedit, and mmg to manipulate MKV files. It functions as a multiplexer, capable of demuxing and muxing data, allowing you to extract and merge codecs within the GUI. You can create new files by splitting content and edit properties during inspection.

The software enables splitting a single file into multiple parts for easier access to specific sections. You can extract audio, subtitles, and video components, and embed subtitles in various languages, such as Arabic, English, or Spanish. MKVToolNix processes tasks quickly, displaying progress in the lower right corner of the interface.

Import media by dragging and dropping files into the ?Input? section of the user interface. The UI populates details into sections like ?Source file? and ?Tracks, chapters, and tags?, showing file name, container type, and size. You can import multiple files or a single file at once.

The ?Tracks, chapters, and tags? area displays multimedia type, codec, and language for each component. You can select or deselect elements to keep or remove them. The GUI allows resizing sections by dragging their edges.

The tabbed interface includes ?Output? and ?Attachments? tabs alongside ?Input?. The ?Properties? section shows details for selected items in the ?Tracks, chapters, and tags? list. For subtitles, you can change the language via a dropdown menu next to ?Language?.

Does MKVToolNix Reduce Quality?

MKVToolNix maintains the original file quality as it does not recode content. It supports MP4 reading and is compatible with video formats like AVC, AVI, Dirac, MPEG, RealVideo, and VC1, as well as audio formats including AAC, DTS, Enhanced AC, FLAC, MP2, MP3, RealAudio, and Vorbis. Supported subtitle formats include ASS, PGS, SRT, and SSA.

After selecting a destination file at the bottom of the screen, click ?Start multiplexing? to process the media. The interface displays the number of active jobs and any errors or warnings detected.

Alternative Apps for Video Handling

Alternatives like Avidemux, FFmpeg, and MakeMKV are audio and video converters that transcode multimedia formats. These editors are free, with Avidemux and FFmpeg being open-source. MakeMKV converts Blu-ray and DVD content into MKV files. Avidemux?s interface resembles VLC Media Player, particularly in its video playback area.

Powerful MKV Management Tool

The MKVToolNix GUI is a versatile utility for altering, generating, and inspecting multimedia files. It is lightweight, consuming minimal system resources, and is safe and ad-free. The MKVToolNix website includes a ?Source Code? tab detailing the software?s current development status.

How Do I Install MKVToolNix on Windows?

MKVToolNix is available as an installer or portable version for Windows PCs. Regular software updates are released, with details on bug fixes available in the ?News? section of the MKVToolNix website.
