WAV 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.
Up to 200 MB
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.

Half the size, zero loss
Shrink your masters without giving up a single sample
A WAV master is huge, and keeping a whole catalog of them fills a drive fast. FLAC squeezes each file to roughly half the size and gives back byte-for-byte identical audio when it's decoded, nothing is thrown away. It's the format for archiving finished masters, sending lossless mixes to a client, or building a library you'll never have to re-rip.
Truly reversible
Lossless means you can always get the WAV back
FLAC isn't 'nearly lossless', it's mathematically reversible, the same way a ZIP file is. Decode the FLAC and the original PCM comes back sample for sample. So archiving as FLAC costs you nothing but disk savings: any time you need the full WAV again, it's one conversion away, unchanged.
DAW-ready
Every current DAW imports it, most players too
Logic, Pro Tools, Reaper, FL Studio, and Ableton all import FLAC in their recent versions, and consumer support is everywhere now, including Apple Music. If you're on an older DAW that still wants WAV, just decode it back first. And like everything here, the compression runs in your browser, your unreleased masters never leave your machine.
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.
