WAV to FLAC converter
Same bits, half the bytes: FLAC packs WAV audio losslessly, ideal for archiving masters. Conversion happens in your browser — the file never touches a server.

FLAC (Free Lossless Audio Codec) works by predicting each sample from the ones before it and storing only the small difference, then entropy-coding what's left. That math typically shaves 30-60% off a WAV's size depending on how busy the audio is, and because nothing is thrown away, decoding reproduces the original PCM samples bit-for-bit. Unlike WAV, FLAC also carries tagging (artist, title, album art) and stores an internal checksum of the audio, so a corrupted file gets flagged instead of playing back as a glitch.
Suno exports and your own bounced masters usually land as WAV, which is uncompressed and grows fast once you're keeping stems, alternates, and multiple takes. Converting WAV to FLAC is the standard move for anyone who wants a smaller archive without touching audio quality — a lossless format you can re-decode to a byte-identical WAV whenever a distributor, mastering engineer, or collaborator asks for one. It's the wrong tool if you need something to stream on a phone or upload to a platform that only accepts MP3 or AAC; FLAC is for keeping the pristine copy, not for casual playback everywhere.
How it works
- 1
Drop the WAV file.
- 2
Pick a compression level (maximum = smallest file, slightly slower).
- 3
Click convert and download the FLAC.
When to use it
- Archiving a full Suno project folder — original download, instrumental, and every re-roll — as FLAC so a year of tracks fits on the drive at roughly half the size.
- Sending a lossless master to a distributor like DistroKid or a mastering engineer who accepts FLAC, without emailing a giant WAV that bounces off attachment limits.
- Building a bit-perfect backup on cloud storage (Google Drive, Dropbox) where the internal FLAC checksum lets you later verify the file never got corrupted in transit.
WAV vs FLAC

| Typical size | Large (uncompressed) | Medium (~50–60% of WAV) |
| Best for | Editing, DAWs, mastering | Lossless archiving |
| Compatibility | All editors & players | Most modern players |
FAQ
Is FLAC really identical to WAV?
Bit-for-bit — decoding a FLAC reproduces the exact original samples, like a ZIP for audio.
Why not just use MP3?
MP3 permanently discards detail. FLAC is for masters and archives; MP3 is for distribution.
Does FLAC keep the metadata and cover art from my file?
FLAC supports Vorbis comment tags (title, artist, album, year) and embedded cover art, which plain WAV largely can't hold. That said, a raw WAV usually has no tags to carry over, so you'll typically be adding that information rather than preserving it — the audio itself converts untouched either way.
What compression level does the converter use, and does it affect quality?
Compression level only changes encoding speed versus file size — the decoded audio is identical at every level because FLAC is lossless. Higher levels search harder for efficient predictors and produce a slightly smaller file that takes longer to encode, but level 0 and level 8 both decode back to the exact same samples.
Will FLAC play on my devices, or do I need to convert back to WAV?
FLAC plays natively in VLC, foobar2000, most Android phones, and modern browsers, but not in some older hardware players or default iOS playback. Since this is lossless, you can convert any FLAC straight back to a bit-identical WAV whenever a tool or device refuses it, with no quality loss in the round trip.
