iTunes and the iPhone Music app do not import FLAC, which leaves a lot of lossless libraries stuck outside the Apple world. Converting FLAC to M4A wraps your audio in an MPEG-4 container that Apple Music adds with a simple drag and drop. The result is smaller than FLAC and ready for your phone, all in your browser with no signup.

The formats

FLAC vs M4A

FLAC

Free Lossless Audio Codec

Lossless audio at about half the size of WAV

Type: Lossless audio format
Holds: Compressed audio with no quality loss
Typical size: About half the size of WAV
Plays on: VLC and most players, not older iPhones by default

Best for:Archiving music at full quality

M4A

MPEG-4 Audio

Apple-friendly AAC audio

Type: Lossy audio, usually AAC
Holds: AAC audio in an MP4 container
Typical size: Small, smaller than MP3 at the same quality
Plays on: iPhone, Mac, iTunes, and most players

Best for:Apple devices and clean compressed audio

Will it lose quality?

Converting a lossy file to a lossless one cannot restore detail that was already discarded. It only makes a larger file.
Going from a high-quality source to M4A keeps the sound clear while changing the format.
Each pass between two lossy formats loses a little, so always convert from the best source you have.

Troubleshooting

If something looks off

The M4A is larger than I expected

Lossless and uncompressed formats are big by design. If you want a smaller file, pick a lossy format and a bitrate around 192 to 256 kbps.

The song details are missing

Title, artist, and album travel as tags when the source has them. If they are blank, add them in any music app after converting.

My app will not open the M4A

Most apps open common audio, but a few are picky. VLC plays almost anything, or convert to MP3 for the widest support.

FAQ

FLAC to M4A questions

Is the FLAC to M4A converter free?

Yes. EchoWave converts FLAC to M4A with no signup, no file-count limit, no trial, and no watermark. Upload your FLAC, convert it, and download the M4A from your browser.

Why convert FLAC to M4A for Apple devices?

iTunes, Apple Music, and the iPhone Music app do not play FLAC by default, but they handle M4A natively. Converting to M4A lets you import a FLAC library into Apple Music by dragging the files in, or using File then Import.

Will I lose quality converting FLAC to M4A?

M4A here uses AAC, which is lossy, so it discards some data that FLAC keeps. At 256 to 320 kbps it stays close to the source for everyday listening, but it is a one-way step, so keep your FLAC files if you want a perfect copy.

What is the difference between M4A and MP3?

M4A holds AAC audio, which is a newer codec than MP3 and usually sounds a little better at the same size. M4A is the natural fit for Apple devices, while MP3 is the safer pick when you need a file that opens absolutely everywhere.

Is M4A the same as AAC?

They are related but not identical. AAC is the codec, and M4A is the MPEG-4 file that usually contains AAC audio. If you want a bare AAC file instead, convert FLAC to AAC.

Does the M4A keep the song title, artist, and cover art?

Title, artist, and album carry over as tags when your FLAC has them, and embedded cover art usually travels too. You can edit any detail in Apple Music or a tag editor after converting.

Can I play the M4A on Android and Windows too?

Yes. M4A is not Apple-only. It plays on Android, Windows Media Player, and most browsers and music apps, plus VLC, so the file is not locked to Apple gear.

Does the FLAC to M4A converter work on iPhone, Android, Mac, and Windows?

Yes. The converter runs in any browser, so you can convert FLAC to M4A on iPhone, iPad, Android, macOS, Windows, Chromebook, and Linux with nothing to install.

Can I convert a whole FLAC album?

Yes. There are no file-count limits on these pages, so you can convert your tracks one after another. Larger files simply take a little longer to upload and convert.
