WAV (Waveform Audio File Format) uses uncompressed lossless encoding and is best for professional audio editing, mastering, and archival in DAWs and production software. FLAC (Free Lossless Audio Codec) uses losslessly compressed encoding and excels at high-fidelity music archives and audiophile listening where quality matters more than file size. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Typically 50–60% of WAV size with bit-identical audio — a 600 MB session folder lands near 300 MB. Decompression is instant on any player.
FLAC carries Vorbis-comment tags plus embedded covers — richer metadata than WAV's limited support. Tag thoroughly at archive time.
Equivalent quality; FLAC is universal, ALAC is Apple-preferred. Archive FLAC, convert copies for Apple workflows.
