You can convert MP4 to audio for free: upload your MP4 above and Flippy extracts the audio as audio in your browser, no signup needed.

Turning MP4 into audio isn't really a conversion: it's an extraction: Flippy lifts the audio track out of your MP4 and re-packs it on its own. You keep the sound and drop the pixels, swapping an MP4 that runs roughly 50–100 MB per minute at 1080p, depending on bitrate for audio in whichever format suits: MP3 for reach, WAV for editing headroom.

Why flip MP4 to audio

MP4 is the world's default video: the file that plays before anyone has to think about it. It was born in 2001, the MPEG standards group, built on Apple's QuickTime design, and its real weak spot is very little day to day: as a container its quality depends on the codec inside.

Whatever the recording, audio just wants to be heard: the trick is picking a shape that plays where you need it. Stands in for any audio format Flippy can read: MP3, WAV, FLAC, AAC and friends. That makes it the right destination when what you need is any sound file: music, voice memos, podcasts, session exports.

Questions people ask

Will converting MP4 to audio lose quality?

No: extraction copies the audio that's already in the MP4. Whatever the soundtrack sounded like inside the video, that's what your audio will sound like.

Will the audio file be bigger or smaller than my MP4?

Much smaller: you're keeping the audio and dropping the video, which is most of the weight. Expect a small fraction of the original.

How long does MP4 to audio conversion take?

It scales with length and resolution: short clips finish in seconds, long HD videos can take a few minutes. Files auto-delete within an hour after.
