About this tool
WAV recordings from field recorders, DAWs and CD rips take up about 10 MB per minute. FLAC compresses the same audio losslessly, usually to around half the size, and decodes back to exactly the same samples. It is the standard format for archiving music and recordings without giving up any quality.
FLAC plays on Android phones, Windows, macOS, most hi-fi players and music servers. The conversion runs on our server with FFmpeg after you agree to the upload, and keeps the original sample rate and bit depth. WAV files can be up to 50 MB, about five minutes of CD-quality stereo, and are deleted within 30 minutes.
