MixMasterAIWAV to FLAC Converter
FLAC compresses PCM audio losslessly — the file shrinks to roughly half the WAV size, but decoding it gives back bit-identical audio. It's the right format for archiving masters, sending lossless mixes to clients, or building a music library you'll never have to re-encode.
How it works
Drop the WAV
Any PCM WAV — 16, 24, or 32-bit float, any sample rate.

Compress at level 8
FLAC compression level only affects encoding speed and file size. The audio is identical at every level. Level 8 (max) takes a bit longer but gives the smallest file.

FLAC plays in VLC, foobar2000, modern Android phones, most DAPs, and Apple Music since 2021. DAW import support is universal in 2024+ versions of Logic, Reaper, FL Studio, and Pro Tools.

Frequently asked questions
How much smaller is a FLAC than the source WAV?
Typically 40-60% smaller, depending on content. A solo piano piece with quiet passages compresses well. A loud, dense full-band master compresses less. The compression is reversible — decoding gives back bit-identical PCM.
Is FLAC truly lossless?
Yes. FLAC uses linear prediction and Rice coding — same idea as ZIP, applied to audio. Decode the FLAC and you get the original PCM samples back, byte for byte. There's no quality loss anywhere in the round trip.
Should I use a higher compression level for archival?
Level 8 is fine for archival — the audio is identical at every level. Higher levels compress slightly better but take longer to encode. For a one-time archive, level 8 is the sensible default. For batch jobs, level 5 is faster with most of the size benefit.
Will my DAW import FLAC?
All recent versions do — Logic Pro 10.4+, Pro Tools 2024+, Reaper, FL Studio 20+, Ableton Live 11+. Older DAWs may need WAV; in that case decode the FLAC back to WAV first or pick a different export from your DAW.
