    FLAC, a compressed but lossless format

    Unlike MP3, FLAC compresses audio without discarding any data: the file is lighter than a WAV but remains bit-for-bit identical to the original recording. It’s the format favored by audiophiles and platforms like Bandcamp for high-fidelity music.

    A size trade-off for mobile use

    An album in FLAC can weigh 3 to 5 times more than in MP3. For listening on a smartphone, in a car, or on a player with limited storage, converting to MP3 sharply cuts the space used, at the cost of a lossy compression that this time is irreversible.

    A one-way conversion

    Once converted to MP3, the file can no longer regain the lossless quality of the source FLAC: it’s best to keep the FLAC original if high-fidelity listening remains possible elsewhere, and create the MP3 only for mobile use.

    Frequently asked questions

    FLAC compresses without losing data (identical quality to the original), while MP3 compresses with loss to shrink the file size further.

    Its larger size makes it less practical for mobile storage or listening on space-limited devices.

    No, data removed by MP3 compression is permanently lost.

    Generally hard to notice outside a high-fidelity audio setup or very attentive listening.
