FLAC to M4R Converter

Convert FLAC to M4R 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 M4R 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 M4R codec — lossy targets shrink size; lossless targets preserve every sample.

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.
