A lecture recording, a voice memo saved as video, a song from a clip: sometimes only the sound matters. Locavert takes the audio track out of the MP4 and saves it as MP3 on your device. If the video already carries MP3 audio the track is copied as is; otherwise it is encoded at a quality set by the slider.
Set a start and end time to keep only the part you need. WAV, FLAC, Opus and AAC are on the same row if MP3 is not what you want. The file never leaves your browser, and the audio tools download once, with a prompt before the download.
