Flippy turns M4A into MP4 for free: upload the M4A above and download it wrapped as MP4, sound untouched.

It sounds backwards, but M4A to MP4 is a real need: plenty of platforms and tools only accept video, so Flippy re-packs your M4A audio inside an MP4 wrapper. Nothing is re-recorded: the sound in your M4A crosses over untouched, and the MP4 that comes out is built for playing everywhere: browsers, phones, TVs, editors, slide decks.

Why flip M4A to MP4

M4A is AAC in Apple's favorite outfit: the audio-only MP4 your iPhone speaks natively. It was born in 2003, popularized by Apple's iTunes Store, and its real weak spot is older Windows software and stubborn car stereos that expect a .mp3.

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 M4A 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 M4A?

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 M4A behind: MP4 simply opens in more of the places that matter.

How long does M4A 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.
