FLAC to M4A Converter
Convert FLAC to M4A online for free. Change audio format for playback, editing, uploads, podcasts, ringtones, archiving, or a better balance between file size and sound quality.
Converting FLAC to M4A re-encodes the audio using the target codec. Sample rate and channel layout are preserved, and ID3 metadata (artist, title, album art) carries over. File size and quality depend on the M4A codec — lossy targets shrink size; lossless targets preserve every sample.

Why Convert FLAC to M4A
M4A is the standard audio format for iPhone, iPad, Mac, and Apple Watch. Voice memos, Apple Music downloads, and iTunes purchases all use M4A for the best playback experience on Apple hardware.
M4A uses AAC encoding, which delivers superior audio quality compared to MP3 at equivalent bitrates. At 256 kbps, M4A is virtually indistinguishable from CD quality to most listeners.
M4A containers can hold Apple Lossless (ALAC) encoded audio for bit-perfect quality. Apple Music Lossless subscribers receive ALAC in M4A files for the highest quality listening experience.
M4A supports chapter markers with titles and artwork, making it ideal for enhanced podcasts. Listeners can jump between segments and see chapter-specific images in compatible podcast apps.
M4A (and its M4B audiobook variant) efficiently compresses long spoken-word content with chapter navigation and bookmark support. Apple Books and other audiobook apps handle M4A files natively.

About the FLAC Format
FLAC (Free Lossless Audio Codec) is an open-source lossless audio codec released in 2001 by the Xiph.org Foundation. It compresses audio files to approximately 50-70% of their original size with absolutely zero quality loss — every single bit of the original recording is preserved and perfectly reconstructable upon decoding.
FLAC is the preferred format for audiophiles, music archivists, and anyone who demands perfect audio fidelity. It is supported by major streaming services including Spotify and Tidal for high-resolution audio delivery, and plays natively on most modern music players and devices. FLAC strikes the ideal balance between lossless quality and practical file sizes, making it the gold standard for music collections where quality matters.
