# Convert AIFF to M4A

Convert AIFF to M4A right in your browser — free, private, nothing is uploaded. Pick a bitrate (32–320 kbps) and shrink the file dramatically.

AIFF is Apple's classic uncompressed audio container — the Mac counterpart to WAV. Same raw PCM audio, same huge files, mostly seen in pro-audio sessions and older Mac workflows.

M4A wraps AAC audio in an MPEG-4 container — the format iTunes and Apple Music use. AAC squeezes better quality than MP3 out of the same bitrate, at the cost of slightly narrower support.

Converting AIFF to M4A trades a sliver of fidelity for a dramatic drop in size: an AIFF recording that hogs storage becomes an M4A file you can email, message or stream. It's the classic move for sharing voice memos, publishing spoken audio and fitting a music library onto a phone.
