Frequently asked questions
Is my MKV uploaded?
No. The conversion runs in your browser with FFmpeg compiled to WebAssembly. The first use downloads the converter (about 30 MB); your file never leaves your device.
What is a MKV file?
MKV is a container that often holds films and TV episodes, sometimes with several audio tracks. FFmpeg uses the main one, normally the one with the most channels.
Is the video kept?
No. Only the sound is saved, as an MP3. The original video file is not changed.
