WAV to FLAC

FLAC shrinks WAV files to roughly half their size without losing a single detail. Convert recordings, albums and masters here, on your own device.

Your files never leave your device

How to use it

  1. Choose your WAV files, or drag them onto the box.
  2. Each one is converted to FLAC on your device.
  3. Download each FLAC file, or all of them together as a ZIP file.

Nothing is lost

FLAC is lossless: played back, the FLAC gives exactly the same samples as the WAV. The sample rate is kept, and 24-bit recordings stay 24-bit. The files are made with the reference FLAC encoder from the Xiph.Org Foundation, running inside your browser.

Good to know

32-bit floating-point WAV files, which some recording programs make, are saved as 24-bit FLAC, which is more detail than any playback equipment can reproduce. FLAC files keep surround sound as it is, up to eight channels.

Questions

Are my files uploaded?

No. The work happens inside your web browser, on your own device. Before your file is opened, this page locks itself: from then on your browser refuses to let it fetch, upload or send anything at all. You can check: once the page has loaded, switch off your internet connection and it will still work. How the lock works.
