Convert MUX files online for free
The converter easily converts your MUX file to various formats - free and online. No Media Player or extra software needed.
The converter also works in reverse, so you can convert other Video formats to MUX with high quality output.
The .MUX extension serves two distinct, incompatible purposes, creating significant confusion for users. Its primary role is within the Linux ecosystem as a temporary video recording file generated by Kazam. These files are typically created during a screen capture session. If the software crashes or the recording is interrupted, the file remains in this temporary .MUX state rather than being finalized into a standard MP4 or WEBM. While effectively a Matroska (.MKV) stream, the file header is often incomplete, making it unreadable to standard players like VLC Media Player or Windows Media Player. To recover this footage, users must convert or remux the file into a stable MP4 (for web compatibility and editing) or MKV (to preserve the raw stream without quality loss).
In a completely different context, .MUX files function as game audio packages for titles running on the ManiaPlanet engine, such as Trackmania by Ubisoft. These are proprietary compressed archives containing music and sound effects. Because these files are locked to the game engine, audiophiles or content creators wishing to use the game's soundtrack cannot open them directly. The solution is converting these internal assets into accessible audio formats like MP3 for listening or WAV for high-fidelity editing.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our MUX converter.
