Convert FLAC to WAV
To convert FLAC to WAV, drop your .flac file into the converter on this page and click Convert to WAV. The decode runs in a WebAssembly build of ffmpeg inside your browser, so the audio is reconstructed on your own machine rather than on a server.

Why convert FLAC to WAV?
You usually land here because a piece of software refuses FLAC. Plenty of samplers, hardware loopers, older DAWs and a few stubborn plugins only ingest plain WAV, so a perfectly good FLAC library is unusable until it is unpacked into raw PCM. WAV is the lowest-common-denominator audio container: if a tool reads audio at all, it almost certainly reads WAV. Converting hands those tools the exact same samples your FLAC held, just stored without compression so the gear does not have to decode anything itself.
What is FLAC?
FLAC (Free Lossless Audio Codec) compresses audio to roughly half of WAV size while keeping every sample bit-perfect, which made it the archival and audiophile standard. It is open and royalty-free, plays in browsers and most modern software, but car stereos, older devices and plenty of apps still want MP3, and audio editors often prefer plain WAV input.
What is WAV?
WAV is uncompressed audio in its plainest form: the 1991 RIFF container holding raw PCM samples, the same data a CD carries. Nothing is lost and nothing is guessed, which makes WAV the standard handoff format for audio editing, mastering, transcription tools and samplers. The price is size: about 10MB per stereo minute, an order of magnitude more than a decent MP3 of the same sound.
Quality and what to expect
This conversion is fully lossless. FLAC is compressed losslessly to begin with, so decoding it to WAV reproduces every sample bit-for-bit: the audio in the WAV is identical to the audio in the FLAC, nothing is approximated or thrown away. The one real consequence is size. WAV stores those same samples with no compression, so the file gets considerably larger, often roughly double, since FLAC was squeezing the data and WAV is not. Sample rate and bit depth carry through unchanged; you are paying disk space to drop the compression layer, not buying or losing any fidelity.
FLAC to WAV FAQ
Does converting to WAV improve the sound?
No, and it cannot. FLAC already stores the audio losslessly, so the WAV holds the exact same samples bit-for-bit. You gain compatibility with raw-PCM tools, not any audible quality, and you lose nothing either.
Why is the WAV so much bigger than my FLAC?
Because WAV applies no compression at all. FLAC was packing those same samples into roughly half the space losslessly, and unpacking them to uncompressed PCM removes that saving, so a doubling in file size is completely normal.
Is my FLAC uploaded anywhere to be decoded?
It is not. The ffmpeg decoder is compiled to WebAssembly and runs in a worker in this browser tab, so the audio stays on your device. You can watch the network panel in developer tools and see no file leave.
Will the WAV keep my original sample rate and bit depth?
Yes. The converter writes PCM at the source FLAC sample rate and bit depth, so a 44.1kHz/16-bit FLAC becomes a 44.1kHz/16-bit WAV. The samples are preserved exactly; only the container and the absence of compression change.
