Why use our WAV to FLAC Converter?

Quality Encoding
Lossless FLAC keeps every bit of the decoded audio.

FAQ
Frequently asked questions
How do I convert WAV to FLAC?
Drop your WAV files onto the page and click Convert. Each file is re-encoded to FLAC in your browser and gets its own Download button.
Is my audio uploaded to a server?
No. Conversion runs entirely in your browser with a WebAssembly build of FFmpeg, so your files never leave your device.
Why convert WAV to FLAC?
FLAC is lossless compression: the audio is bit-for-bit identical to the source at roughly half the size of WAV.
Will I lose audio quality?
FLAC is lossless, so nothing is lost from the decoded audio. If the source was a lossy format like MP3, the result is as good as that source.
Can I convert several WAV files at once?
Yes. Drop in as many as you like and they all convert in one pass, each with its own download.
Is this converter free?
Yes. It is free to use with no sign-up, no account, and no watermark on your files.
