FLAC files are uncompressed and huge. M4A uses lossy compression to shrink them by 90% or more. The size reduction is significant for sharing, uploading, and storage.
For email attachments, 128-192kbps works well. For music sharing, use 256-320kbps. AudioUtils lets you drop your file and convert instantly. No upload to a server, no waiting.
FLAC is lossless. Converting to M4A reduces file size at the cost of some audio data. Use a high bitrate to minimize loss. Choose the right bitrate for your use case. Higher bitrate means better quality but larger files.
Frequently Asked Questions
How does M4A quality compare to FLAC?
At 256kbps AAC, the difference from FLAC is nearly imperceptible in normal listening. You lose the lossless guarantee, but the audible quality is excellent.
Will my FLAC metadata transfer to M4A?
Yes. M4A has excellent metadata support — title, artist, album, track number, and album art all transfer cleanly.
Is M4A the same as AAC?
M4A is the container file format, and AAC is the codec inside it. M4A files almost always use AAC compression. Think of M4A as the box and AAC as what's inside.
