You can convert AVI to AAC for free: upload your AVI above and Flippy extracts the audio as AAC in your browser, no signup needed.

Turning AVI into AAC isn't really a conversion: it's an extraction: Flippy lifts the audio track out of your AVI and re-packs it on its own. You keep the sound and drop the pixels, swapping an AVI that runs usually bulky: its era's codecs compress far less than H.264 or H.265 for an AAC built for streaming-grade sound at friendly file sizes.

Why flip AVI to AAC

AVI is the veteran of desktop video: dependable in 1995, cranky about everything invented since. It was born in 1992, Microsoft, and its real weak spot is modern life: no proper streaming, no subtitles, no love for modern codecs.

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.

Questions people ask

Will converting AVI to AAC lose quality?

No: extraction copies the audio that's already in the AVI. Whatever the soundtrack sounded like inside the video, that's what your AAC will sound like.

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

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.

Where will the AAC file play?

Apple everything, YouTube, Android, modern players; patchy on legacy gear. That's the usual reason people leave AVI behind: AAC simply opens in more of the places that matter.

How long does AVI to AAC 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.
