AIFF vs AMR 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. AMR is the codec built for phone calls — optimized for speech at very low bit rates, but rarely playable outside dedicated voicemail or call-recording apps.

AIFF to AMR — frequently asked questions

Is this AIFF to AMR converter really free?

Yes — completely free, with no sign-up, no watermarks and no daily limits.

Will I lose quality converting to AMR?

AMR 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.
