You can convert AVI to MP3 for free: upload your AVI above and Flippy extracts the audio as MP3 in your browser, no signup needed.

Turning AVI into MP3 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 MP3 built for playing on anything with a speaker, from new phones to twenty-year-old car stereos.

Why flip AVI to MP3

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.

MP3 is the format that taught music to travel: small, scrappy, and welcome absolutely everywhere. MPEG-1 Audio Layer III. Perceptual coding: it throws away the parts of the signal your ear is least likely to miss. That makes it the right destination when what you need is playing on anything with a speaker, from new phones to twenty-year-old car stereos.

Questions people ask

Will converting AVI to MP3 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 MP3 will sound like.

Will the MP3 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 about 1 MB per minute at 128 kbps: roughly a tenth of CD audio.

Where will the MP3 file play?

Everything. Phones, browsers, cars, smart speakers, ancient iPods. That's the usual reason people leave AVI behind: MP3 simply opens in more of the places that matter.

How long does AVI to MP3 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.
