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.

Lossless compression — identical audio, 30–60% smaller
Proper metadata: title, artist, album and cover art
Ideal for archiving a lossless music library
Private uploads, auto-deleted after 1 hour
No watermark, no signup to try
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.
