FLAC to WAV Converter — Free, Local, No Upload

The short answer: FLAC and WAV are both lossless, so converting FLAC to WAV changes the packaging, not a single sample: the FLAC decodes to PCM and is stored raw as 16-bit WAV, bit-identical to what any FLAC player would produce. The reason to do it is tool compatibility — DAWs, samplers, embedded systems, and older editors that read WAV but not FLAC.

How to convert FLAC to WAV

Convert FLAC to WAV now

The button opens the Audio Converter with FLAC → WAV preselected — it runs entirely in your browser and nothing is uploaded.

Open Audio Converter

Local in your browser — nothing is uploaded

  1. Open the converter

    The button above opens the Audio Converter with the WAV output already selected.

  2. Drop your FLAC file

    Add the file (up to 200.0 MiB); the format is verified from its signature, not its name.

  3. Convert and download

    Press Convert; the ffmpeg audio engine (~31 MB) downloads on first use, then your file transcodes in a dedicated worker. Cancel stops the run cleanly.

FLAC → WAV

What to watch

Nothing audible is lost — the WAV is bit-identical to the FLAC's decoded audio, so the conversion is genuinely lossless and the bitrate tiers are ignored. What you pay is size: uncompressed PCM typically runs 50–100% larger than the FLAC it came from, roughly 10 MB per minute at CD quality. Outputs are capped at 200 MiB (inputs too), with a 5-minute per-run watchdog; the ~31 MB engine downloads on first use, then stays cached on your device.

    Convert MP3, WAV, M4A, OGG and FLAC audio between formats entirely in the browser with ffmpeg.wasm — no uploads. Inputs up to 200 MB with 96/128/192 kbps bitrate tiers for lossy output; OGG uses Opus and WAV/FLAC stay lossless.

Frequently asked questions

Will converting FLAC to WAV lose any audio quality?
No — both formats are lossless, and the WAV stores exactly the samples the FLAC decodes to. Decoding the WAV later returns the identical audio; only the packaging changed from compressed to raw PCM.
Which bitrate should I choose for the WAV?
None — WAV is uncompressed PCM, so the bitrate tier selector stays visible but the encoder ignores it, and the workspace says so. The file size follows the decoded sample rate, channel count, and duration, which is why the WAV is typically half again as large as the FLAC it came from.
Are my audio files uploaded anywhere?
No. Decoding and encoding run in a WebAssembly build of ffmpeg inside your browser tab — the file never leaves your device, nothing is uploaded or stored on a server, and closing the tab discards everything.
