WAV to FLAC Converter

Why convert WAV to FLAC?

FLAC is what a WAV archive should have been. It is mathematically lossless — every sample recoverable — while taking roughly half the space, and unlike WAV it stores proper tags for artist, album and track.

WAV holds uncompressed PCM audio — exactly what the microphone or mixdown produced. Studios, podcasters and transcription tools want it; storage and email do not.

When WAV → FLAC is the right move

• Archiving recordings or CD rips without giving up any quality.
• Halving the storage a session or library consumes.
• Adding searchable metadata that WAV cannot store properly.

Quality, size and what changes

Compression is lossless, so decoding a FLAC back to WAV returns bit-identical audio. Expect files around 50–60% of the original, with the exact ratio depending on how dense and loud the material is.

What you gain with FLAC: Lossless quality at roughly half the size of WAV, with rich tagging support.

How it works

Drop your WAV file above and Morphio decodes it locally, then re-encodes it as FLAC using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.
