Expi leverages the FFmpeg library to provide a simple yet powerful way to convert media files. Users can drag and drop files into the app, select output formats, and choose from a variety of presets. The app handles all processing locally, using the user's computer resources rather than cloud services. This ensures complete privacy and eliminates reliance on internet connectivity.
