Why convert AIFF to MP3?

AIFF is uncompressed Apple audio, roughly 10 MB per minute. MP3 cuts that by around 90% while staying perfectly listenable for previews, sharing and everyday playback.

How it works

Drop your AIFF 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.
