WAV stores raw, uncompressed PCM samples — the audio equivalent of a bitmap. Files are huge, but every editor, DAW and operating system opens them without a second thought.

FLAC compresses audio without losing anything — a perfect, bit-for-bit copy at a fraction of the WAV size, which makes it the default choice for archiving music.

Converting WAV to FLAC is a pure win for storage: the copy is bit-for-bit identical to the original, at typically 50–70% of the WAV size.

How the conversion works

  1. Choose your WAV file (up to 10 MiB). The button above opens the converter with FLAC already selected as the target format.
  2. There is no bitrate to choose: FLAC is lossless, so the bitrate field is simply ignored.
  3. Run the conversion and download the result — the output keeps your filename with a .flac extension. Everything happens locally: the page runs ffmpeg compiled to WebAssembly, so your audio is never uploaded to a server.

What to expect

Nothing is lost either way. WAV and FLAC both store audio losslessly, so the samples come through bit for bit — only packaging and file size change. The bitrate setting doesn't apply to a lossless target.

Embedded album art is dropped along the way: cover images ride along as a video stream, which audio-only outputs like FLAC can't carry.

FAQ

Is converting WAV to FLAC really lossless?

Yes — both formats store the audio losslessly, so the conversion is bit-transparent. What changes is packaging and file size, not sound.

How much smaller will the FLAC file be?

Typically 50–70% of the WAV size — FLAC's compression is lossless, so the saving comes free. Exact ratios depend on the material: quiet, simple audio shrinks further than dense, loud mixes.

Is my WAV file uploaded when converting to FLAC?

No. The page downloads an ffmpeg WebAssembly build once, then converts your file locally in the browser tab — the audio never leaves your device. Input files up to 10 MiB are supported.
