Flippy turns AAC into AVI for free: upload the AAC above and download it wrapped as AVI, sound untouched. No signup, and both files delete themselves within an hour.

It sounds backwards, but AAC to AVI is a real need: plenty of platforms and tools only accept video, so Flippy re-packs your AAC audio inside an AVI wrapper. Where AVI accepts your AAC's codec the sound crosses over untouched; where it doesn't, it's re-encoded once. The AVI that comes out is built for opening old archives and humoring legacy Windows tools.

A classic AAC to AVI job: iTunes-era rips and app exports, bound for legacy Windows tools that never learned newer containers.

Why flip AAC to AVI

AAC is MP3's better-trained successor: cleaner sound from the same number of bits. It was born in 1997, an MPEG all-star team: Fraunhofer, Dolby, Sony, AT&T and Nokia, and its real weak spot is older or stubborn hardware that only ever learned MP3.

AVI is the veteran of desktop video: dependable in 1995, cranky about everything invented since. Audio Video Interleave: an early container that predates streaming and most codecs you'd use today. That makes it the right destination when what you need is opening old archives and humoring legacy Windows tools.

Best settings for AAC to AVI

Settings for AAC to AVI: none to pick. Where the AVI container accepts your AAC's audio codec, the stream is copied bit for bit; where it doesn't, Flippy re-encodes it once and leaves the levels alone.

AAC vs AVI, side by side

	AAC	AVI
Born	1997, an MPEG all-star team: Fraunhofer, Dolby, Sony, AT&T and Nokia	1992, Microsoft
Type	audio · lossy	video · container
Best for	streaming-grade sound at friendly file sizes	opening old archives and humoring legacy Windows tools
Weak spot	older or stubborn hardware that only ever learned MP3	modern life: no proper streaming, no subtitles, no love for modern codecs
Typical size	similar to MP3, but it sounds better at the same bitrate: or the same at about 25% smaller	for video content, usually bulky: its era's codecs compress far less than H.264 or H.265; wrapping audio alone stays about the size of the AAC
Plays on	Apple everything, YouTube, Android, modern players; patchy on legacy gear.	Old Windows software and desktop players; phones and browsers mostly refuse.

Questions people ask

Will converting AAC to AVI lose quality?

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

Will the AVI file be bigger or smaller than my AAC?

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

Where will the AVI file play?

Old Windows software and desktop players; phones and browsers mostly refuse. That's the usual reason people leave AAC behind: AVI simply opens in more of the places that matter.

How long does AAC to AVI conversion take?

Seconds for most AAC files: there are no pictures to encode, so wrapping the audio as AVI is nearly as fast as copying it. Both files auto-delete within an hour.
