Convert AIFF to MP3
AIFF is what WAV is, from the Apple side of the family: uncompressed, exact and very large.
Audio only · up to 10 files · 100 MB each — those numbers protect your memory, not our server
Getting the converter ready — this happens once, then your browser keeps it.
The converter could not start.
The engine files are missing from — copy ffmpeg-core.js and ffmpeg-core.wasm there.
Almost always a mismatched build: the worker is an ES module, so the core has to be the esm one too. Copy ffmpeg-core.js and .wasm from @ffmpeg/core/dist/esm/, not dist/umd/.
not in this build of the converter, so it is not offered.
What you lose
The same as WAV to MP3 — real, permanent, and inaudible to most people above 192 kbps.
What you do not gain
Size and compatibility. AIFF opens on far fewer things than its age suggests.
What it does to the size
Approximate, for stereo audio at the settings this tool uses by default. The real figure moves with the material — silence and speech compress far better than a full mix.
When this is the right conversion
Getting audio out of Logic, GarageBand or an older Mac workflow and into something anybody can play.
