Convert FLAC to WAV
Convert FLAC lossless audio to uncompressed WAV format directly in your browser. WAV is required by older DAWs, CD authoring software, and some hardware samplers that don't support FLAC. The conversion is bit-perfect since both formats preserve the full PCM signal. No upload needed.

When to Convert FLAC to WAV
- Converting FLAC archival masters to WAV for CD authoring in Nero Burning ROM or Toast Titanium
- Preparing FLAC studio masters as WAV for loading into hardware samplers like the MPC Renaissance
- Converting FLAC tracks from a Hi-Fi music library to WAV for DJ controllers that require WAV files
- Loading FLAC sound design assets as WAV into older versions of Pro Tools that don't read FLAC
- Converting FLAC concert recordings to WAV for editing in legacy audio software with no FLAC support

//how_it_works
How It Works
Drop your FLAC files
Drag and drop or select FLAC files at any sample rate or bit depth. First use loads FFmpeg WASM (~30MB).
FFmpeg decodes FLAC
FFmpeg WASM parses the FLAC container and decompresses the linear-predicted Rice-coded data back to raw PCM samples bit-perfectly.
Write uncompressed PCM WAV
PCM samples are written as uncompressed signed little-endian PCM with a RIFF WAV header at the source sample rate and bit depth — no resampling.
Download your WAV files
Your WAVs are bit-identical to the FLAC source and ready for any DAW, CD authoring tool, or hardware sampler.
// under the hood
FLAC uses linear prediction with Rice coding for lossless compression of PCM samples. WAV is a RIFF container holding raw PCM with no compression. Our converter uses FFmpeg WASM with the native FLAC decoder to decompress the FLAC stream to raw PCM at its native sample rate and bit depth, then writes the PCM as uncompressed signed little-endian PCM with a standard RIFF WAV header. The conversion is bit-perfect.

Frequently Asked Questions
- Is the FLAC to WAV conversion lossless?
- Yes — completely. Both FLAC and WAV preserve the full PCM signal exactly. FLAC is just a compressed container around PCM; decoding to WAV recovers the original samples bit-for-bit. There is zero quality difference between the FLAC and the resulting WAV.
- Why convert if both are lossless?
- WAV is required by older DAWs (some pre-2015 versions), CD authoring software like Nero or Toast, hardware samplers like the MPC Renaissance, and many DJ controllers. WAV's RIFF header is universally readable. Use WAV when your destination tool doesn't support FLAC.
- What's the WAV file size?
- About 10 MB per minute of stereo at 44.1kHz/16-bit, or 30 MB per minute at 48kHz/24-bit. A typical 4-minute FLAC (~25 MB compressed) becomes a ~40 MB WAV (uncompressed). WAV is bigger because it stores PCM with no compression at all.
- Are sample rate and bit depth preserved?
- Yes. We decode FLAC at its native sample rate and bit depth (typically 44.1kHz/16-bit for music or 48kHz/24-bit for studio masters), then write WAV at the same parameters. No resampling, no dithering, no quality changes.
- Are my FLAC files uploaded?
- No. FFmpeg WebAssembly runs entirely in your browser. Your FLAC files never leave your device.
