Convert WAV to FLAC
Pack a WAV into FLAC and keep every sample intact, at roughly half the size. It runs in your browser, so the file never leaves your device.
Why convert WAV to FLAC?
FLAC holds the exact audio a WAV does, just with lossless compression, so a CD-quality album that runs about 10 MB per minute as WAV lands at 50 to 60 percent of that as FLAC. It also carries proper tags and cover art, which bare WAV headers barely handle, so albums stay labeled and sorted. Music servers like Plex and Roon, foobar2000, and VLC all read it, and hardware streamers have caught up. Convert your WAV masters to FLAC when you want a tagged, space-saving archive that decodes straight back to WAV whenever a DAW or an editor needs raw PCM.
Quality and file size
This is a lossless to lossless conversion, so every sample is preserved bit for bit and the audio does not change at all. FLAC just packs the same PCM data more efficiently, which is why the file shrinks while decoding back to the identical original. Think of it as a zip built for audio: nothing is discarded, only stored more compactly. Playback is broad now, though some older car head units and a few Apple apps still skip native FLAC, so keep an ALAC or M4A copy for those.
WAV to FLAC: common questions
Does FLAC lose any quality compared to WAV?
No. FLAC is lossless, so it stores the exact same samples as the WAV, bit for bit. The only thing that changes is the file size.
How much smaller will the FLAC be?
Usually 50 to 60 percent of the WAV size, depending on the material. Dense, busy mixes compress less than sparse or quiet ones.
Is my WAV uploaded anywhere?
No. The conversion runs entirely in your browser using FFmpeg compiled to WebAssembly, so your WAV never leaves your device and we never see or store it.
Can I get the WAV back from the FLAC?
Yes. Because FLAC is lossless, you can decode it back to WAV and recover the identical original PCM with no degradation.
