What is AIFF?
Apple's uncompressed format. Similar to WAV but with better metadata support. Used in professional Mac audio workflows.
What is M4A?
Apple's preferred audio format. Better quality than MP3 at same bitrate. Default for iTunes and Apple devices.
Why Convert AIFF to M4A?
AIFF files are massive and uncompressed. M4A using AAC compression shrinks them by 80-90% while preserving audio quality that rivals the original. If you're moving audio from Mac production tools into your iTunes library or onto iPhone, M4A is the format Apple's ecosystem expects.
Frequently Asked Questions
How much smaller will the M4A be compared to AIFF?
About 85-90% smaller. A 50MB AIFF file typically becomes 5-7MB as M4A at 256kbps.
Will I lose audio quality?
AAC is a lossy codec, so some compression happens. At 256kbps, the difference from the AIFF original is nearly imperceptible in normal listening.
Can I play M4A on non-Apple devices?
Yes. Android supports M4A natively, and most modern media players handle it fine.
