Convert FLAC to WAV

None. FLAC is lossless, so decoding it to WAV gives you the exact original audio, just uncompressed. The only change is a larger file that any editor or device will accept.

No. The conversion runs with WebCodecs on your device, so the audio never leaves the browser — no account, no quota, no size limit. Chrome, Edge and Firefox work best.

Because some tools only speak WAV. Older audio editors, certain DAWs, hardware samplers, CD-authoring software and some game engines expect uncompressed PCM and will not open a FLAC at all. WAV is the lowest-common-denominator format that every one of them reads. You trade disk space for compatibility — the audio is identical either way, since both hold the same lossless samples.

Expect it to roughly double, sometimes more. FLAC typically compresses to around half the size of the same audio as WAV, so decoding it back to WAV undoes that saving. A three-minute CD-quality track is about 30 MB as WAV; an hour of audio runs to several hundred megabytes. It is a working format, not a storage one — keep the FLAC as your archive copy and use the WAV only where a tool demands it.

Yes — the WAV carries the same sample rate and bit depth the FLAC stored (typically 44.1 or 48 kHz, 16- or 24-bit), because decoding FLAC is exact and nothing is resampled. The result is a bit-for-bit representation of the original audio in an uncompressed wrapper, which is precisely what an editor or transcription pipeline wants to start from.
