Why pull audio out of AVI files?
AVI files are bulky and built for a different era. Many modern phones and players struggle with them, and the video track eats up storage. If all you need is the sound — a speech, a song, an old home movie’s audio — MP3 gives you a small file that plays on anything.
AVI to MP3 FAQs
Will my old AVI files work here?
If your browser can play the AVI’s audio, we can convert it. Most standard AVI files work fine. Very old or exotic codecs may not play in a browser — in that case, try re-saving the file with a modern tool first.
Is my file uploaded to a server?
Never. Everything happens locally in your browser, so your old videos stay completely private.
How much smaller will the MP3 be?
Dramatically. A 500 MB AVI can become a 5–10 MB MP3, because you’re dropping the entire video track and compressing the audio.
What’s the maximum file size?
200 MB per file. For best results, keep files under 100 MB.
