Should you convert WAV to FLAC?
You’re archiving recordings and want to halve the storage without losing a single bit of quality.
A lossless move: WAV and FLAC both keep every sample, so the sound is identical and you can convert back at any time.
WAV is uncompressed, studio-quality audio; FLAC is lossless audio at roughly half the size of WAV. Use FLAC to archive music and recordings you may want to convert again later.

What changes when WAV becomes FLAC
Identical sound
Both formats are lossless, so the audio isn’t changed at all. Only the file size and which apps open it differ.
Expect a smaller file
FLAC usually stores the same content in less space than WAV. WAV: About 10 MB a minute at CD quality. FLAC: About 5–7 MB a minute for music.
This page is put together from our notes on each format, choosing only what is true of WAV and FLAC, so every pairing states the same facts the same way. How these pages are made.
Why it doesn’t upload
Recordings are often private: interviews, voice notes, unreleased music. Your browser can decode and encode audio itself, so there is no reason to send it anywhere.
How to check for yourselfWorth knowing
- About the WAV. A WAV made from an MP3 is ten times bigger but sounds exactly like the MP3; the lost detail doesn’t come back.
- About the FLAC. FLAC made from an MP3 is lossless only in name: it perfectly preserves an already lossy recording, at five times the size.
- MP3, WAV, M4A, OGG, Opus and FLAC are converted by your browser directly. WMA, AMR, APE, AC3 and the other specialist formats use the FFmpeg engine, a one-time 31 MB download.
