Why convert AIFF to MP3?
AIFF files from GarageBand or Logic Pro are uncompressed and large — a 4-minute recording can weigh 40 MB or more. Converting to MP3 shrinks it dramatically while sounding nearly identical, and plays on any device instead of just macOS software.
AIFF vs MP3 at a glance
AIFF is Apple's uncompressed audio format — the Mac equivalent of WAV, lossless and studio-standard but with much less support outside professional audio software. MP3 is the universal audio format — plays on every device and app since the late 90s, smaller than WAV with near-identical quality.

AIFF to MP3 — frequently asked questions
Is this AIFF to MP3 converter really free?
Yes — completely free, with no sign-up, no watermarks and no daily limits.
Will I lose quality converting to MP3?
MP3 uses lossy compression, so the image is re-encoded at high quality (92%). For photos the difference is practically invisible; for text-heavy graphics or logos, a lossless format like PNG preserves sharp edges better.
Is the conversion private?
Audio conversion runs on our servers with ffmpeg — your file is deleted immediately and never stored.
