Convert FLAC to WAV

This free FLAC to WAV converter changes your Free Lossless Audio Codec (.flac) file into a Waveform Audio (.wav) file, right in your browser. There is nothing to install, no account to create, and no limit on how many files you convert.

100% private. Your file is processed locally in your browser with WebAssembly — it is never uploaded to a server, stored, or seen by anyone.

Share this tool

The conversion runs on your own device using ffmpeg compiled to WebAssembly (ffmpeg.wasm), so your file is never uploaded to a server. WAV is best for uncompressed editing and mastering, which is the usual reason to convert from FLAC.

Why convert FLAC to WAV?

  • WAV plays on more devices and apps than FLAC, so it is the safer choice for sharing.
  • Expect a larger file: WAV (largest) is less compressed than FLAC.
  • Pick WAV when you need a file made for uncompressed editing and mastering.

How to convert FLAC to WAV

  1. Add your FLAC file

    Drag and drop your .flac file onto the upload area, or click to browse and pick it from your device.

  2. Start the conversion

    Click "Convert to WAV". Everything runs locally with ffmpeg compiled to WebAssembly (ffmpeg.wasm) - your file stays on your device.

  3. Wait a few seconds

  4. Download your WAV file

    When it finishes, download the .wav file straight to your device.

Frequently asked questions

Is this FLAC to WAV converter free?
Yes. It is completely free with no signup, no watermark, and no limit on how many files you convert. It is supported by ads, which keeps the conversion itself free.
Are my files uploaded to a server?
No. The conversion runs locally in your browser using ffmpeg compiled to WebAssembly (ffmpeg.wasm), so your file is processed in memory on your own device and is never uploaded, stored, or seen by anyone.
Will I lose quality converting FLAC to WAV?
WAV is lossless, but the source is decoded and re-encoded, so the result can only match - not exceed - the quality already in your FLAC file.
Will the file get smaller or larger?
Larger. WAV (largest) is less compressed than FLAC (large), so expect a bigger file.
What is the difference between FLAC and WAV?
FLAC is Free Lossless Audio Codec (a FLAC container, typically FLAC); WAV is Waveform Audio (a WAV container, typically PCM). WAV is best for uncompressed editing and mastering, while FLAC is best for lossless archiving of music.
How long does the conversion take?
Most files finish in a few seconds to under a minute, depending on length and your device. The first conversion is a little slower while the engine downloads and caches, then later runs start instantly.
