FAQ

Frequently asked questions

Is the sound quality truly preserved?

Yes. FLAC is a lossless format and stores exactly the same audio data as the WAV file, just packed more efficiently. You lose no quality at all.

Why use FLAC instead of WAV?

FLAC is usually 30 to 60 percent smaller than WAV and supports metadata like titles and cover art. That makes it excellent for long-term archiving.

Are my files sent to a server?

Not by default. Conversion runs directly in your browser. Only if you choose the optional server mode for very large files does the data leave your device.

Can I turn FLAC back into WAV?

Yes, anytime and without loss. Because FLAC keeps every bit of the original, you can recover a bit-identical WAV file from it.
