FAQ
Is FLAC really lossless?
Yes, literally. Decoding a FLAC returns exactly the samples that went in. It compresses by removing redundancy, not by discarding detail, the same way ZIP does with a document.
How much smaller will the file be?
Typically 50–60% of the WAV, depending on the material. Quiet or sparse recordings compress more; dense loud mixes compress less.
Is there a quality setting?
No, because there is no quality decision. Compression level only affects how hard the encoder works and how small the result is — the decoded audio is identical either way.
Will my software read FLAC?
Almost certainly. Most editors, players, phones and both Windows and Android support it. The holdouts are some samplers and embedded tools that only accept raw PCM.
Should I archive in FLAC or WAV?
FLAC. It is the same audio in half the space, and it stores checksums so you can verify the file has not degraded — something WAV cannot do.
Is it really free?
Yes — every conversion on this site, with no account, no watermark and no daily cap. The work happens on your own device, so there is no server bill for us to pass on to you.
Do I need to install anything?
No. It runs in any modern browser, on Windows, macOS, Linux, Android and iOS. There is nothing to download and nothing to sign up for, and once the page has loaded it keeps working with the network switched off.
