Right for speech, wrong for music. At a fixed quality the file size does not change — but mono tolerates a much lower quality than stereo, so combine the two to actually shrink the file.

Leave at 0 for the whole file.

0 means run to the end.

  • No upload The conversion runs in this tab. Your file never travels — not to us, and not to the advertising.
  • No sign-up, no email, no daily cap There is no account system to sign up to.
  • No size limit we invented Only your device's memory — about ~2 GB on a desktop browser, ~400 MB on a phone.
  • Turn your Wi-Fi off and convert anyway The conversion needs nothing but this page. Ads will not load without a connection; your file will still convert. That is the whole claim, and it takes five seconds to check.

Decompresses FLAC into WAV. This is one of the few conversions on this site that loses absolutely nothing — FLAC is lossless, so the WAV contains exactly the same samples.

Bit-for-bit identical

FLAC is compression in the same sense as ZIP: the original samples are recoverable exactly. Decoding to WAV produces the identical PCM stream the FLAC was made from.

The file roughly doubles in size, because FLAC typically compresses to 50–60% of WAV. Nothing else changes — same sample rate, same bit depth, same audio.

Why you would want the larger file

Some hardware and software still does not read FLAC: older DAWs, samplers, CD-authoring tools, in-car systems, and a surprising amount of professional broadcast equipment. WAV is the universal donor.

If everything in your chain reads FLAC, keep the FLAC — it is the same audio in half the space.

Bit depth

A 24-bit FLAC is written here as 16-bit PCM, which is CD quality and the most compatible WAV variant. If you specifically need 24-bit — you are mastering, not listening — use a desktop tool that preserves the depth.

Both are lossless, so nothing is decided here

FLAC is WAV with the redundancy squeezed out, typically to about half the size, and decoding reproduces the original samples bit for bit. There is no quality setting to get wrong and no generation loss to worry about, which makes this one of the few conversions on this site where the only thing that changes is how many bytes it takes to say the same thing. The reason to do it is compatibility: audio editors, games engines and hardware samplers that will not read FLAC will read a WAV without complaint.

Questions

Is any quality lost?
None. FLAC is lossless, so the WAV contains exactly the same samples.
Why is the file twice as big?
FLAC compresses losslessly to about half the size of WAV. Decoding restores the uncompressed form.
Do I get 24-bit?
No — 16-bit PCM, the most compatible variant. Use a desktop tool if you need to preserve a 24-bit depth.
Is my file uploaded?
No. The demuxing, decoding and encoding all happen in this tab using the browser’s own media stack plus a WebAssembly encoder. A recording can be an interview, a lecture, a private call — none of it is transmitted. Turn your Wi-Fi off after the page loads and it still works.
How large a file can I convert?
There is no imposed limit, only your device’s memory — around 2 GB in a desktop browser and 400 MB on a phone, since the file is held in memory while it converts. A two-hour video converts in well under a minute on a laptop.
