Convert FLAC to WAV online
Convert a FLAC file to WAV directly in your browser — the file is never uploaded to a server.

Convert a FLAC file into a WAV file. Since FLAC is lossless, decoding it produces audio that's bit-for-bit identical to the original — the only real change is that WAV takes up more space on disk.
FLAC compresses audio without discarding any information, the same way a ZIP file shrinks a document without losing data. Decoding it back to WAV simply unpacks those exact samples into an uncompressed PCM container — no audio detail is added or removed in the process.
Use cases
- Get a WAV version of a lossless FLAC track for a car stereo or older device that doesn't support FLAC.
- Import lossless audio into a DAW or hardware sampler that only reads WAV.
- Prepare FLAC music for software that has no FLAC decoder at all.
How it works
- 1
Upload your FLAC file
Drop the file in or select it from your device.
- 2
Click Convert
ffmpeg.wasm decodes the FLAC and writes it out as PCM WAV directly in your browser.
- 3
Download the WAV
Once it's done, download the resulting file.
Technical details
Runs ffmpeg.wasm in your browser. Because FLAC's compression is fully reversible, the resulting WAV is sample-for-sample identical to what the FLAC file was encoded from; the only difference is file size, since FLAC's compression typically shrinks audio by 40 to 60% compared to the equivalent uncompressed WAV.
Frequently asked questions
Will I lose any audio quality converting FLAC to WAV?
No. FLAC is a lossless format, so the decoded WAV is bit-for-bit identical to the original audio — nothing is discarded.
Why bother if FLAC already sounds perfect?
Because some hardware and older software simply can't decode FLAC but can play any WAV file; converting is about compatibility, not quality.
