About This Tool
MKV (Matroska Video) is a popular open-source container format commonly used for high-definition movies, TV shows, and anime. It can hold multiple audio tracks, subtitles, and chapters in a single file. Sometimes you only need the audio from an MKV file — perhaps a concert recording, a podcast saved as video, or a movie soundtrack. This tool extracts the audio track from your MKV file and converts it to MP3 format for easy playback on any device. All processing happens directly in your browser using WebAssembly technology for complete privacy.
