Most free converters add watermarks or throttle quality. AudioUtils does neither. You get the same output quality whether free or paid.

Free users get 5 conversions per month with a 10-second preview output. The conversion engine is identical to Pro — same speed, same quality, same privacy. Upgrade for full-length output.

Your files stay on your machine. Nothing is uploaded. 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.

About M4A
