Build Your iTunes Library from Lossless FLAC Rips
iTunes and Apple Music accept M4A files and sync them to every Apple device. FLAC files are not on Apple's supported import list. Converting FLAC CD rips and archival recordings to M4A imports them directly into the iTunes library with full metadata — album art, artist, genre, track number — and makes them available for sync to iPhone, iPad, and HomePod.

Open FLAC Recordings as GarageBand Project Tracks
GarageBand on Mac and iPad imports M4A audio files directly into projects as audio regions. FLAC files cannot be opened in GarageBand. Podcast producers, musicians, and songwriters who work from FLAC masters can convert to M4A and drag recordings into any GarageBand project for editing, adding music beds, applying effects, and exporting finished audio.

FLAC to M4A: Open Lossless Archive to Apple's Native Music Container
FLAC is the universal lossless archive format. M4A is Apple's native music container — the format iTunes creates, Apple Music downloads in, and GarageBand works with. Converting between them brings a lossless library into Apple's music management ecosystem.

Our converter uses FFmpeg to decode FLAC losslessly and encode as AAC in an M4A container at a high bitrate.

Frequently Asked Questions
What is the difference between FLAC to M4A and FLAC to AAC?
AAC is the audio codec — the compression algorithm. M4A is the container file format that holds AAC audio. Converting FLAC to M4A produces a .m4a file containing AAC audio — the same audio as a plain .aac file, just in the MPEG-4 container that iTunes, GarageBand, and Apple Music expect. For Apple ecosystem use, M4A is the correct output format.
Why can't I import FLAC directly into iTunes?
iTunes and Apple Music support AAC (.m4a), MP3, WAV, AIFF, and Apple Lossless (ALAC). FLAC is an open-source format not included in Apple's supported list. Converting to M4A with AAC encoding is the standard approach for adding FLAC music to an iTunes library.
Should I convert FLAC to M4A with AAC or with ALAC?
If you want a compressed file for efficient iPhone storage and everyday listening, use AAC inside M4A — it produces the best possible AAC quality from a lossless source at a fraction of the FLAC file size. If you want bit-for-bit identical quality to the FLAC master with no quality loss at all, convert to ALAC (also stored in .m4a). Both are valid choices depending on your storage and quality priorities.
Can I open the converted M4A in GarageBand on Mac?
Yes. Drag the .m4a file into a GarageBand project window and it will appear as an audio region on a track. GarageBand imports M4A on both Mac and iPad natively.
Will the M4A sync to all my Apple devices via iCloud Music Library?
Yes. Once an M4A is imported into Apple Music on a Mac with iCloud Music Library enabled, it uploads and becomes available on every Apple device signed into the same Apple ID — iPhone, iPad, Mac, HomePod, and Apple Watch.
Is there a file size limit?
The upload limit is 100 MB per file. Most FLAC audio tracks are well within this limit.
