FLAC to WAV
Nothing is uploaded. The conversion runs here, on this device.

What this does
This is the rare conversion where nothing at all is lost. FLAC is lossless compression: it stores the complete recording in less space, and decoding it gives back the identical samples. The WAV that comes out is not a copy of the audio — it is the audio, bit for bit.
FLAC is lossless, so files are large, but everything is still in them. What FLAC lacks is universal support in audio software.
Lossless in, identical out
Every other pair on this site trades something away. This one does not: run a FLAC through it and the samples in the WAV are exactly the samples that went into the FLAC, which you can verify by converting back and comparing. What changes is the size and the compatibility. The WAV will be roughly twice the size of the FLAC — that is the compression coming off — and it will open in software that never learned to read FLAC, which is most older editors, samplers and hardware. Use it when a tool insists on WAV; keep the FLAC as the thing you archive.
Nothing is uploaded
The conversion happens inside this page. Your file is read by the browser, converted here, and saved straight back to your downloads. It is never sent to a server, so there is no upload wait and no size cap beyond what your own device can hold.
Open your browser’s developer tools, switch to the network panel, and convert a file. You will see the converter itself download once, and no upload of your audio at all. That is the whole difference between this and a site that converts on a server, and what that difference actually means is worth a read.
The first conversion is slower
The converter is about 32 MB and downloads the first time you use it, which is the one moment this page is not instant. After that it is cached, and later conversions start immediately, even offline. So do later visits.
Questions
Do I lose any quality?
None whatsoever. FLAC is lossless, so decoding it returns the original samples exactly. This is one of only two conversions here where that is true.
Why is the WAV about twice the size?
Because the FLAC was compressed and the WAV is not. FLAC typically stores a recording in 50–60% of its uncompressed size; converting simply undoes that, and no audio is added or removed.
Will the tags survive?
Mostly not. FLAC stores metadata as Vorbis comments, and WAV has almost nowhere to put them. Keep the FLAC if you need the title, artist and album; the WAV is the working copy.
