Why convert MKV to MP3?
MKV is a video container that can hold several audio tracks. This tool extracts the primary audio track and saves it as an MP3 that plays everywhere. Video and subtitles are discarded on purpose so you get a lightweight audio file. Protected or encrypted videos are not supported.
Pick the right MP3 quality
Not sure which bitrate to choose? Use Auto for a good balance. For voice (talks, lectures), 64–96 kbps in mono keeps speech clear and compact. For music, 160–192 kbps in stereo is a solid choice. Higher bitrates mean larger files; lower bitrates shrink size with some loss of detail.
