Convert WAV to FLAC
Convert WAV files to FLAC format instantly in your browser. FLAC stores every bit of your audio with zero quality loss but at 40-60% of the WAV file size — the audiophile standard for music archiving. No upload needed.

When to Convert WAV to FLAC
- Archiving a vinyl record or cassette digitized as WAV to FLAC to halve storage costs without any quality loss
- Converting a 24-bit 96kHz WAV studio recording to FLAC for distribution on Bandcamp or Qobuz Hi-Res
- Compressing a large WAV music library to FLAC for a Plex, Jellyfin, or Navidrome home media server
- Converting WAV CD rips to FLAC for permanent lossless backup before also creating MP3 listening copies
- Preparing WAV stems to FLAC for upload to a mastering engineer who requests lossless FLAC delivery

How It Works
Drop your WAV files
Drag and drop or select WAV audio files. 16-bit or 24-bit PCM, mono or stereo, any sample rate supported. First use loads FFmpeg WASM (~30MB).
FFmpeg reads raw PCM
FFmpeg WASM reads the uncompressed PCM from the WAV container. No decoding is needed — WAV is already raw audio. Everything runs locally in your browser.
FLAC lossless compression
libFLAC applies linear predictive coding and Rice entropy coding at level 8 — maximum compression with zero quality loss. The FLAC file decodes to bit-identical PCM.
Download FLAC files
Your FLAC files are ready — 40-60% smaller than the WAV originals with zero quality loss. Perfect for archives, Plex servers, and audiophile music libraries.
// under the hood
WAV stores raw Linear PCM (typically 16-bit or 24-bit at 44.1kHz or 48kHz) with no compression. FLAC uses Linear Predictive Coding (LPC) to model audio signals and Rice coding (a form of entropy coding) to compress the residuals — all reversible with zero data loss. Our converter uses FFmpeg WASM to read the WAV PCM directly and encode with libFLAC at compression level 8, which provides maximum compression with identical decode quality to level 0. Both 16-bit and 24-bit WAV inputs are supported.

Frequently Asked Questions
- What is the difference between WAV and FLAC?
- Both WAV and FLAC are lossless audio formats that preserve the original audio perfectly. The difference is compression: WAV stores raw uncompressed PCM data while FLAC applies lossless data compression (similar to ZIP for images) that reduces file size by 40-60% without discarding any audio information. Decoding FLAC produces byte-identical output to the original WAV.
- Is there any quality difference between WAV and FLAC?
- No — this is a truly lossless conversion. FLAC decodes to exactly the same PCM data as the original WAV. The only difference is file size. This makes WAV to FLAC the ideal archival conversion: you save storage without sacrificing a single bit of audio quality.
- How much smaller will the FLAC be than my WAV?
- FLAC typically reduces file size by 40-60% compared to WAV. A 40MB WAV file usually becomes 15-25MB FLAC. The compression ratio depends on audio complexity — highly dynamic music compresses less than voice recordings or silence-heavy tracks. We use FLAC compression level 8 for maximum size reduction.
- Does FLAC support metadata tags?
- Yes. FLAC supports Vorbis comment tags (TITLE, ARTIST, ALBUM, TRACKNUMBER, DATE, etc.) natively. WAV has limited metadata support via the ID3 or LIST chunk, which many players ignore. Converting to FLAC gives you proper metadata support in every serious audio player and DAW.
- Is this conversion private?
- Yes. All processing runs locally in your browser via FFmpeg WebAssembly. Your WAV files never leave your device — no upload, no server, no access by anyone.
