Flippy turns audio into MP4 for free: upload the audio above and download it wrapped as MP4, sound untouched.

It sounds backwards, but audio to MP4 is a real need: plenty of platforms and tools only accept video, so Flippy re-packs your audio audio inside an MP4 wrapper. Nothing is re-recorded: the sound in your audio crosses over untouched, and the MP4 that comes out is built for playing everywhere: browsers, phones, TVs, editors, slide decks.

Why flip audio to MP4

Whatever the recording, audio just wants to be heard: the trick is picking a shape that plays where you need it. It was born in wherever your microphone, DAW or download came from, and its real weak spot is nothing in particular; the limits belong to whichever format it happens to be wearing.

MP4 is the world's default video: the file that plays before anyone has to think about it. A container, most often carrying H.264 or H.265 video with AAC audio. That makes it the right destination when what you need is playing everywhere: browsers, phones, TVs, editors, slide decks.

Questions people ask

Will converting audio to MP4 lose quality?

No. Wrapping audio in an MP4 container doesn't touch the sound itself: it's the same stream in a different box.

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

About the same, plus a sliver of container overhead. The audio stream is unchanged; MP4 just adds a video-shaped envelope.

Where will the MP4 file play?

Every browser, phone, TV and editing app worth mentioning. That's the usual reason people leave audio behind: MP4 simply opens in more of the places that matter.

How long does audio to MP4 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.
