Why Convert WAV to FLAC?

WAV stores raw PCM, which is honest and enormous. FLAC compresses that same audio 40 to 60 percent smaller and throws nothing away, so decoding the FLAC gives you back a file bit-for-bit identical to the WAV.

It is the sensible way to keep a lossless master without paying full uncompressed storage for it.

Frequently Asked Questions

Is FLAC really lossless, or does it lose a little?
Genuinely lossless. Decode the FLAC and you get back the exact PCM samples from the WAV, with no rounding and no artifacts. Think of it as ZIP for audio, not as MP3.
How much smaller will the FLAC be?
Usually 40 to 60 percent, depending on the material. Dense, busy music compresses less than sparse recordings, but nothing is discarded either way.
Can I get the original WAV back later?
Yes. Convert the FLAC back to WAV and the samples are identical to what you started with, which is the entire point of a lossless codec.
Do all players support FLAC?
Most modern players and phones do now, though some older hardware and a handful of Apple apps still lag. If a device refuses FLAC, keep the WAV or make an MP3 for it.
Is this conversion free, and is my file private?
Yes. The conversion runs in your browser tab, nothing is uploaded, and no account is needed. Files up to 100 MB convert here, limited to 3 conversions per day on this path; the desktop app has neither cap.
