Convert FLAC to WAV

FLAC is where careful people keep their audio; WAV is what stubborn software wants handed to it. Editors that will not import FLAC, samplers that stream raw PCM from disk, transcription workflows with a fixed intake format — this page unpacks the FLAC in your browser and hands back a WAV. Lossless in, uncompressed out: your files are never uploaded on the way.

How to convert FLAC to WAV

  1. Drop your FLAC files

    Several at once is fine — each converts on its own row, and one bad file does not stop the rest.

  2. Check the target says WAV

    WAV is pre-selected on this page; MP3 is one press away if what you actually need is something small.

  3. Save the WAVs

    Each file downloads on its row, or take all of them at once as a zip.

What you get

No loss was ever in the chain

FLAC is lossless compression — the exact samples, packed smaller. Unpacking to WAV is decompression, not conversion between codecs, so nothing about the sound is thrown away in the unpacking — bit depth and rate are a separate question, answered below.

The shape editors expect

Out comes 16-bit PCM at 44.1 kHz — CD shape, the format editors, samplers and DAWs take without a plugin. Hi-res sources are resampled to it, and the FAQ says so rather than hiding it.

Decoded by the browser you already trust

FLAC decoding is built into every current browser engine — measured here in Chromium, Firefox and WebKit. No wasm decoder to fetch, nothing to install; the first file converts immediately.

Your archive stays your archive

People convert FLAC in batches — masters, rips, field recordings. All of it decodes in this page; your files are never uploaded.

Questions about FLAC and WAV

Is FLAC to WAV really lossless?
The decode is: FLAC stores the exact samples, and unpacking them loses nothing. One honest caveat — output here is 16-bit at 44.1 kHz, so a 24-bit or 96 kHz FLAC is resampled to CD shape on the way. For playback and normal editing that is inaudible; for a mastering archive, keep the FLAC.
Why is the WAV so much bigger than the FLAC?
Because FLAC was doing real work: it typically packs the same samples into 50–70% of the space. WAV stores them raw, which is exactly why fussy software likes it — no decoder needed, cut anywhere.
Why do editors and samplers insist on WAV at all?
Raw PCM can be streamed from disk by trivial code and cut at any sample without decoding around the cut. Compressed formats decode in frames — which is why some tools refuse them and others import them slowly.
Should I just keep everything as WAV then?
No — FLAC is the better archive: half the size, checksummed against corruption, tags intact. Convert to WAV when a tool demands it; keep the FLAC as the master.
Is it free, and are my files uploaded?
Free, no account, no limit on count. Decoding and rewriting happen in your browser — your files are never uploaded.
