Convert WAV to FLAC.
Compress bulky WAV files by 30–60% with zero quality loss. FLAC keeps every sample and adds proper tags. Converted with a local engine, private, and auto-deleted after 1 hour.
Same audio, half the size
A WAV stores audio uncompressed, so the files are big, a few minutes of stereo can run tens of megabytes. FLAC applies lossless compression: it packs the exact same samples into a smaller file and unpacks them perfectly on playback. Nothing is thrown away, so there's no quality cost, only the size drops, usually by 30–60%.
Better for a music library
FLAC also does things WAV can't do well: it carries proper tags: title, artist, album, track number and embedded cover art, so your library stays organised. That, plus the smaller size, makes FLAC the standard for archiving and streaming lossless music.
Need uncompressed again?
Because it's lossless, you can decode back to a bit-identical WAV any time with FLAC to WAV when a tool needs uncompressed PCM.

WAV to FLAC: no added loss
FLAC is a lossless format, so encoding into it adds no further quality loss. Note that if WAV was already lossy (like MP3 or AAC), detail discarded earlier can't be brought back. The FLAC is faithful to the WAV, just larger.

Common questions
Is it free?+
Yes. Convert WAV to FLAC free, with no signup.
Is my file private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour.
Does compressing to FLAC lose quality?+
No. FLAC is lossless. It reconstructs the exact original samples, so a FLAC and the WAV it came from sound identical. You only lose the wasted space.
How much smaller will it be?+
Typically 30–60% smaller than the WAV, depending on the music. Busy, full-range tracks compress less; sparse or quiet audio compresses more.
