About this tool
Converting WAV to FLAC
WAV stores audio uncompressed — every sample bit-exact, editing-grade quality, at roughly ten times the size of MP3. FLAC compresses audio losslessly — typically half the WAV size with every sample bit-identical. It is the archival format of music collectors and audiophiles. FLAC compresses the WAV losslessly — bit-identical audio at roughly half the storage, the standard archival move.
What to check after converting
Listen to a section you know well — the beginning, the loudest part — and compare it against the original file. The FLAC output is bit-identical to the source. Your original file stays untouched on your device either way.
Frequently asked questions
Will converting WAV to FLAC reduce the quality?
No further loss — FLAC stores the decoded audio exactly, though what earlier lossy encoding discarded stays discarded.
Is my audio file uploaded anywhere?
Small files convert entirely in your browser; larger ones finish on our servers and auto-delete within an hour. Either way, nothing is kept, shared, or used for anything else.
Why would I pick FLAC over WAV?
FLAC compresses the WAV losslessly — bit-identical audio at roughly half the storage, the standard archival move.
