Extracts the audio track; the video is discarded.

Pulling the audio out of a video

Lifting the sound out of an MP4 is what most people come here for — to save a song or mix, or to keep a podcast, interview or recorded lecture as something to listen to on the move. You end up with just the audio, in a far smaller file.

Morphr decodes the MP4’s audio track and encodes it as MP3 in your browser. The video is discarded; only the sound is kept. Since it’s a real re-encode, a long video takes a little time, and you’ll see progress as it runs.

Good to know

The private way to turn MP4 video into MP3

With Morphr, the whole conversion runs inside your browser tab using your browser's built-in decoder, so your file is never uploaded to a server, queued, or stored. That makes it a safe choice for personal photos, scanned documents and anything you'd rather not hand to a third party.
