    About FLAC

    FLAC is lossless compressed audio: the full quality of a CD in about half the size of a WAV. Many phones, cars and portable players can’t play FLAC, and FLAC files are still large to carry around.

    An MP3 at 320 kbps is a third to a quarter of the FLAC’s size.

    Quality and size

    Choose 128 kbps for speech, 192 kbps (the default) for most music, or 320 kbps for the best quality. MP3 is lossy: converting can’t add quality the original didn’t have. The result is about 1.4 MB a minute at 192 kbps.

    Private by design

    Converters that upload your file keep a copy on someone else’s server, at least for a while. Here the conversion happens on your device, with your browser’s own audio decoders and an MP3 encoder that runs in the page. Nothing is uploaded, and it works on Windows, Mac, Linux and Chromebooks.

    Questions and answers

    Is this FLAC to MP3 converter free and safe?

    Yes. It’s free, with no sign-up and no watermark. Your FLAC files are converted by your browser on your device and never uploaded, so nobody else sees them.

    Should I keep the FLAC files?

    Yes, keep them as your originals. Make MP3 copies for devices that don’t play FLAC or don’t have room for it.

    Can I convert several files at once?

    Yes. Choose or drop as many as you like. They convert one after another, and each gets its own Download button.

    How large can a file be?

    The whole file is read into your browser’s memory, so very large files depend on your device. Audio up to about an hour, and videos up to a few hundred megabytes, work well on most computers.
