Your privacy matters. No signup means no tracking profile tied to your conversions. No email list. No data to breach. AIFF is lossless. Converting to M4A reduces file size at the cost of some audio data. Use a high bitrate to minimize loss.
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.
