Convert WAV to FLAC online
Convert a WAV file to FLAC directly in your browser — the file is never uploaded to a server.
or click to select it
Convert a WAV file (uncompressed audio, the typical format when exporting from an audio editor or ripping a CD) to FLAC, a lossless format that's roughly 40-60% smaller without sacrificing a single bit of quality, directly in your browser.
Unlike MP3 or AAC, FLAC doesn't throw away information to shrink the file: it compresses the same waveform more efficiently, the same way a ZIP compresses a document. The result takes up noticeably less space than the original WAV, but playing it back reconstructs the exact same PCM signal.
Use cases
- Archive a collection of uncompressed WAV masters or recordings while saving disk space, without losing any quality.
- Shrink podcast recording sessions before storing them long-term.
- Prepare WAV files exported from a DAW for a player or library app that prefers FLAC.

Technical details
Runs ffmpeg.wasm in your browser. Typical size reduction is around 40-60% versus the source WAV, though it varies with content — a recording with lots of silence or little variation compresses better than a dense mix with heavy background noise.
Frequently asked questions
Do I lose quality converting WAV to FLAC?
No. FLAC is a lossless format: decompressing it produces exactly the same audio signal as the original WAV, sample for sample.
If there's no quality loss, why not just keep the WAV?
FLAC takes up considerably less space for the same content and, unlike WAV, supports metadata (title, artist, cover art) the way MP3 does.
