LoMux is a lightweight cross-platform GUI for FFmpeg. Its goal is to make common audio/video conversions as simple, free, and open source as possible for the layman. Driven by the extremely powerful CLI driven FFmpeg, LoMux comes with prebuilt executables for 64-bit macOS, Linux, and Windows. If you prefer not to install FFmpeg system-wide, you can drop the static ffmpeg and ffprobe binaries into the bin/<platform>/ folders.

Homebrew (macOS):
brew install ffmpegAPT, DNF, Pacman (Linux)
sudo apt-get install ffmpeg
sudo dnf install ffmpeg
sudo pacman -S ffmpegWinget (Windows)
winget install ffmpegAlternativly you can download and install a static build or you may drag ffmpeg + ffprobe exes into bin/<platform>/ (if on Linux, make them chmod +x). LoMux will look both in the system path and the bin folder for versions of FFmpeg to use.
Install them via your python package manger:
pip install pyinstaller \
ttkthemes \
rich \
pillow
apt install python-pyinstaller \

- Move
LoMux/folder wherever you plan on storing it or delete it if FFmpeg is installed. The only file you need with ffmpeg installed is the prebuiltLoMux.app. Otherwise you will need the/binfolder to store ffmpeg/ffprobe exe files. - Double-click LoMux.app in Finder.
- If macOS Gatekeeper “verifies” it, wait a moment. If it still closes on first run, open Terminal and run:
open /path/to/dist/LoMux.app/
- (Optional) You may attempt to bypass gatekeeper from closing the app by
cd /path/to/Lomux/and using:codesign --force --deep --sign - dist/LoMux.app xattr -dr com.apple.quarantine dist/LoMux.app
