Why convert AVI to MP3?

Old AVI recordings frequently hold audio worth keeping — lectures, tapes, home videos. MP3 extraction gives you a small, playable file you can put on a phone or in a podcast app.

How it works

Drop your AVI file above and Morphix decodes it locally, then re-encodes it as MP3 using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle.
