Turn a lossless FLAC file into an uncompressed WAV file.
The FLAC to WAV converter turns FLAC audio (Free Lossless Audio Codec) into WAV (Waveform Audio File Format (RIFF, usually uncompressed PCM)) directly in your browser. WAV is accepted by every editor, while FLAC support is still missing in some professional and legacy tools.
FLAC is lossless compression — typically 50–60% of the size of the equivalent WAV while decoding bit-identically. WAV is the editing and archiving standard — uncompressed, sample-accurate and supported by every audio application. Both formats are lossless, so the audio stays identical.
Your file is decoded to 32-bit floating-point samples by the browser’s own audio decoder — and at the file’s own sample rate, not a resampled one. You can optionally resample or switch channels. It is then encoded to WAV on your device; for a lossy target the result is decoded again for the preview, so you hear what you will get. Typical size: about 10 MB per minute for 16-bit 44.1 kHz stereo.
Source format facts: FLAC files are lossless; usual bandwidth: full bandwidth, exactly as recorded. Target facts: WAV is lossless; usual bandwidth: full bandwidth up to the Nyquist limit.
Use FLAC masters in editors lacking FLAC.
Many editors prefer WAV.

No — lossless to lossless.
No; WAV has limited tagging.
Going to WAV is lossless. Going to MP3 uses a standard 192kbps encode by default (adjustable), which is transparent for most listening but is a lossy step if your source was uncompressed.
No — the file is decoded and re-encoded entirely in your browser using the Web Audio API and, for MP3, a small bundled encoder. Nothing is sent anywhere.
This tool runs entirely in your browser using the Web Audio API. Nothing is uploaded, stored or shared — there is no server to send your file to, so it works offline once the page has loaded.
