Sometimes you only need the sound: a lecture you want to listen to on your commute, a podcast recorded as video, a song performance, an interview you need to transcribe, or audio for a sample library.
An MP3 file is a fraction of the size of the source video, plays on absolutely everything, and works with every audio app, editor, and transcription service.
Our tool reads the MP4, discards the video stream, and encodes the audio to MP3 right in your browser - no upload, no queue, no watermarks.
Fublix's MP4 to MP3 converter processes everything locally in your browser using WebAssembly. Your video never leaves your device.
That makes it safe for meeting recordings, private lectures, and any other sensitive material.
