Turning video into AAC isn't really a conversion: it's an extraction: Flippy lifts the audio track out of your video and re-packs it on its own. You keep the sound and drop the pixels, swapping a video that runs anywhere from short clips to multi-gigabyte recordings for an AAC built for streaming-grade sound at friendly file sizes.
A classic video to AAC job: camera clips, screen recordings and downloads, bound for streaming-grade playback at friendly sizes.
Video is the heaviest thing most of us ever attach: screen recordings, camera clips, whole talks. It comes from wherever your camera, screen recorder or download made it.
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 video 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 video 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 video sets the ceiling: an extraction can match it, never beat it.
| video | AAC | |
|---|---|---|
| Born | wherever your camera, screen recorder or download came from | 1997, an MPEG all-star team: Fraunhofer, Dolby, Sony, AT&T and Nokia |
| Type | video · any format | audio · lossy |
| Best for | any moving picture: recordings, rips, exports, downloads | streaming-grade sound at friendly file sizes |
| Weak spot | nothing inherently; every container brings its own quirks | older or stubborn hardware that only ever learned MP3 |
| Typical size | anywhere from short clips to multi-gigabyte recordings | similar to MP3, but it sounds better at the same bitrate: or the same at about 25% smaller |
| Plays on | Depends on the container and the codec inside it. | Apple everything, YouTube, Android, modern players; patchy on legacy gear. |
The AAC is encoded once from the exact track inside the video: 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 video 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.
