What is M4A?

Apple's preferred audio format. Better quality than MP3 at same bitrate. Default for iTunes and Apple devices.

What is FLAC?

Lossless compression. Perfect quality at roughly half the size of WAV. The choice for audiophiles and archiving.

Why Convert M4A to FLAC?

Moving away from Apple's ecosystem? FLAC is the universal lossless format supported by nearly every non-Apple device and player. While converting lossy M4A to FLAC won't restore lost data, it puts your files in an open format that works everywhere and prevents further quality degradation from future conversions.

Frequently Asked Questions

Does converting M4A to FLAC improve audio quality?

No. M4A typically uses lossy AAC compression, and that lost data can't be recovered. FLAC stores the audio losslessly from this point forward, preventing further degradation.

Why convert to FLAC if it doesn't improve quality?

FLAC is open-source and supported by nearly every media player outside Apple. It also preserves the current quality exactly — no further loss from future format conversions.

Will FLAC files be larger than M4A?

Yes, typically 3-5x larger. FLAC is lossless, so it stores more data per second of audio than the compressed M4A source.
