Turning MOV into AAC isn't really a conversion: it's an extraction: Flippy lifts the audio track out of your MOV and re-packs it on its own. You keep the sound and drop the pixels, swapping a MOV that runs frequently huge: camera and ProRes MOVs can run to gigabytes per minute for an AAC built for streaming-grade sound at friendly file sizes.
A classic MOV to AAC job: iPhone footage and camera originals, bound for streaming-grade playback at friendly sizes.
MOV is Apple's homebody: gorgeous on a Mac, awkward everywhere else. It was born in 1991, Apple's QuickTime team, and its real weak spot is traveling: Windows, Android and the web would all rather meet an MP4.
AAC is MP3's better-trained successor: cleaner sound from the same number of bits. Advanced Audio Coding: the default soundtrack of YouTube, iTunes and most MP4 video. That makes it the right destination when what you need is streaming-grade sound at friendly file sizes.
Drop your MOV file into the flipper above, or click to browse for it.
Check the output format: AAC is already selected for you.
Hit Convert, give it a moment, then download your new AAC.
Quality tip for MOV to AAC: AAC turns transparent for most ears around 192 to 256 kbps, and it degrades more gracefully than MP3 below that. The track inside your MOV sets the ceiling: an extraction can match it, never beat it.
| MOV | AAC | |
|---|---|---|
| Born | 1991, Apple's QuickTime team | 1997, an MPEG all-star team: Fraunhofer, Dolby, Sony, AT&T and Nokia |
| Type | video · container | audio · lossy |
| Best for | shooting and editing on Apple hardware, where it's the native tongue | streaming-grade sound at friendly file sizes |
| Weak spot | traveling: Windows, Android and the web would all rather meet an MP4 | older or stubborn hardware that only ever learned MP3 |
| Typical size | frequently huge: camera and ProRes MOVs can run to gigabytes per minute | similar to MP3, but it sounds better at the same bitrate: or the same at about 25% smaller |
| Plays on | Mac and iPhone natively; elsewhere it depends on the player's mood. | Apple everything, YouTube, Android, modern players; patchy on legacy gear. |
The AAC is encoded once from the exact track inside the MOV: from a typical soundtrack the difference is inaudible, but it can't sound better than what the video carried.
Much smaller: you're keeping the audio and dropping the video, which is most of the weight. Expect similar to MP3, but it sounds better at the same bitrate: or the same at about 25% smaller.
Apple everything, YouTube, Android, modern players; patchy on legacy gear. That's the usual reason people leave MOV behind: AAC simply opens in more of the places that matter.
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.
