Frequently asked questions

Does this keep the video, or just the audio?

Only the audio is kept — the video stream is discarded and the soundtrack is saved as a standalone MP3 file, so you end up with a small, listenable clip instead of a bulky old video.

Why extract audio from an old AVI file?

Old recordings, lectures, music videos or home movies are sometimes only available as AVI. Extracting the audio gives you a small, universally playable MP3 you can keep on a phone, without dragging the heavy legacy video along.

Where do AVI files usually come from?

AVI is an old Microsoft container from the DivX/XviD era: video downloads of the 2000s, clips off old camcorders and digital cameras, and files burned to CDs and DVDs back then. That vintage is exactly why AVI now feels awkward on modern phones and apps.

Will a very old or unusual AVI still work?

Usually yes. AVI can wrap many different codecs — MP3, AC3, PCM and older ones — and the converter reads the audio stream it finds and re-encodes it to MP3, so you do not have to identify or install anything for odd old files.

Will the audio quality drop, and how small is the result?

The audio in an AVI is often already MP3 or AC3, and it is re-encoded once to a clean MP3 — a small lossy step that is inaudible for normal listening. The result is a fraction of the video's size, easy to email or keep on a phone.

Can I extract audio from several AVI files at once?

Yes. Add all your AVI files together and click Convert — each one's audio is extracted as a separate MP3, so a folder of old clips converts in one pass with no limit on file count.
