The format

What is a FLAC file?

  • Free Lossless Audio Codec

    FLAC compresses audio without losing any quality, usually to about half the size of a WAV file. Music collectors and hi-res music stores use it because it keeps CD-quality or better audio bit for bit.

  • What opens FLAC files

    Windows 10 and 11, Android, VLC, foobar2000, browsers, and most hi-fi players. On iPhone and Mac it plays in the Files app, QuickTime, and VLC, but the Music app can't import it.

FAQ

Questions, answered

Is the FLAC converter free?

Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.

Are my files uploaded anywhere?

No. Everything runs inside your browser with Mediabunny and your browser's WebCodecs video encoders, so your files never leave your device. Once the page has loaded, it even works offline.

Does it work on iPhone, Android, Mac, and Windows?

Yes. It works in current versions of Chrome, Edge, Safari, and Firefox. Phones handle short clips well, and long or 4K videos convert best on a computer.

MP3, WAV, OGG, Opus, M4A, AAC, and AIFF. Pick the format after adding your file.
