Convert WAV to FLAC
The one conversion on this site that costs nothing at all. FLAC stores exactly the same audio in roughly half the space.
Audio only · up to 10 files · 100 MB each — those numbers protect your memory, not our server
Getting the converter ready — this happens once, then your browser keeps it.
The converter could not start.
The engine files are missing from — copy ffmpeg-core.js and ffmpeg-core.wasm there.
Almost always a mismatched build: the worker is an ES module, so the core has to be the esm one too. Copy ffmpeg-core.js and .wasm from @ffmpeg/core/dist/esm/, not dist/umd/.
not in this build of the converter, so it is not offered.
What you lose
Nothing. Not "almost nothing" — nothing. Convert back to WAV and you get a bit-for-bit identical file.
What you do not gain
About half the disk space, and a format that carries proper tags, which WAV handles badly. Audio quality is unchanged, because it is the same audio.
What it does to the size
Approximate, for stereo audio at the settings this tool uses by default. The real figure moves with the material — silence and speech compress far better than a full mix.
When this is the right conversion
Archiving masters, recordings or a sample library. If you are storing WAV files long-term, this is close to free money.
Other conversions
This tool is free because dbelo is a library of sound effects, and we would rather you found us this way than not at all.
