WAV to FLAC Converter

Runs in your browser — your files are never uploaded.

Convert WAV to FLAC and keep every single sample. FLAC is lossless compression: it typically halves the size of a WAV, and decoding gives back a bit-for-bit identical waveform. That makes it the right choice for archiving masters and recordings where MP3 or OGG would be throwing away detail you cannot recover. Runs entirely in your browser.

Frequently asked questions

Is any quality really lost?+

None whatsoever. FLAC is mathematically lossless — decode it and you get exactly the samples the WAV contained. It compresses audio the way ZIP compresses documents.

How much smaller is FLAC than WAV?+

Typically 40–60% smaller. Quiet, sparse recordings compress the most; loud dense masters the least. It will never reach MP3 or OGG sizes — that is the trade you are choosing.

Should I pick FLAC or OGG?+

FLAC to archive or edit further, OGG or MP3 to distribute and save space. If this file is your only copy of a recording, FLAC is the safer choice.

What plays FLAC?+

Practically every modern player and platform — VLC, foobar2000, Android, recent Windows and macOS, Bandcamp, Plex. Older car stereos and some cheap portable players are the usual holdouts.

Is my file uploaded anywhere?+

No. Once the engine has loaded, compression happens entirely inside your browser tab.
