Citrus Get Citrus Convert AIFF to M4A (AAC) on Mac, offline
Need to turn a .aiff file into M4A (AAC)? Citrus converts AIFF to M4A (AAC) right on your Mac, offline, using Apple's own engines. Nothing is uploaded to any server, which matters for client work, private photos and contracts.
What to expect
M4A (AAC) is lossy, so you trade a little audio data for a much smaller file. Choose a bitrate in Citrus; 256 kbps is a good default for music. How to convert AIFF to M4A (AAC)
Open Citrus from the menu bar (the citrus slice icon). Drop your .aiff file, or several, into the window. You can also drag a file onto the menu bar icon to open the quick wheel. Choose M4A (AAC) as the output format and adjust options if you want, like size, quality or resolution. Press Convert. Your new files appear next to the originals, and the originals are never changed. About the formats
AIFF: AIFF is Apple's uncompressed audio format, equivalent to WAV in quality.
M4A (AAC): M4A with AAC is the compact lossy audio format used by iPhone, Apple Music and most devices.
