Convert FLAC to WAV
Turn FLAC into plain WAV for software and hardware that will not read FLAC, on your own device.
- Nothing is uploaded
- Works offline after first use
- Open source
- No sign-up, no watermark. The limit is your device’s memory (phones hold less).
Convert FLAC to WAV in your browser for CD burning, DJ software and audio editors. It is free, needs no account and adds no watermark, and your files are not uploaded: everything runs in your browser on your device. The limit is your device’s memory, which is smaller on a phone, and after your first run the page works offline.
Your iPhone may take a few seconds to prepare the video first, longer if it's stored in iCloud.
Done
Open the network tab. Your files never appear in it.
Add files and run the tool to see every request this tab makes.
Your files are processed on this device and never sent to a server. Reload the page to clear everything from memory.
FLAC and WAV hold the same kind of audio; FLAC just compresses it without loss. You need the WAV when something refuses FLAC: CD burning software, older versions of Rekordbox, Serato and Traktor, CDJs and other hardware players reading from USB, some video editors, and audio tools on Windows that predate FLAC support.
The FLAC is decoded by your browser and written straight out as a WAV file in this tab. The WAV is 16-bit at 44.1 kHz, which is exactly CD audio, so a CD rip converts with every sample kept. Hi-res FLAC at 24-bit or 96 kHz is reduced to CD resolution on the way; keep the originals if you need the hi-res versions for anything else.
Expect the WAVs to be about twice the size of the FLACs, around 600 MB for a full album. Nothing is uploaded, so the size only matters for your own disk, and a whole album converts in one drop.
DJs run into this most. Rekordbox exports to CDJs, older Serato versions and many club players read WAV, AIFF and MP3 but not FLAC, and finding out at the venue is the worst time. Converting a crate the night before takes a few minutes here, and because each WAV keeps the FLAC’s file name, your playlists and cue notes still match the tracks.
How it works
- Drop FLAC tracks or a whole album, or tap to pick them.
- WAV is already selected. Leave it on stereo for music.
- Convert. The WAVs download together as a zip.
In your browser, not on a server
Your browser decodes the sound track with the same audio decoders it uses to play media on any website (AAC for MP4, MOV and M4A; Opus or Vorbis for WebM; FLAC, WAV and MP3). The samples are resampled to 44.1 kHz and handed to LAME, the reference MP3 encoder, compiled to WebAssembly and served by this site. WAV files are written directly by a few lines of code in the page. Everything happens in memory in your tab.
Compared with upload-based tools: Online converters upload the whole video just to keep its sound, cap free files at a few hundred megabytes, and make you wait in a queue. Home videos, lectures and voice memos are personal. Here the file never leaves your device, so a 1 GB video converts as fast as your computer can read it, and the limit is your device’s memory (phones hold less).
Verify it yourself. Give the page a short while after your first run to save itself for offline use, then turn off Wi-Fi or switch to airplane mode and run the tool again. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.
Questions
Is FLAC to WAV lossless?
For CD-quality FLAC (16-bit, 44.1 kHz), yes: the WAV contains the same samples. Hi-res FLAC is converted to 16-bit, 44.1 kHz, which is lossless for anything played from a CD but not a bit-perfect copy of the hi-res file.
Can I burn the WAVs to an audio CD?
Yes. They are in the CD format already. Add them to your burning software in track order; the file names keep their track numbers.
Why is the WAV twice as big?
FLAC packs the same audio into roughly half the space, the way a zip file does. WAV stores every sample as-is, which is why hardware and older software can read it without a decoder.
Are the artist and title tags kept?
No. WAV has only limited tag support and the page writes the audio alone. Keep the track name in the file name, which carries over unchanged apart from the extension.
Is the file uploaded anywhere?
No. There is no server in this process. The page is a static file and the work is done by code running inside your browser tab. Give the page a short while after your first run to save itself for offline use; then you can turn off Wi-Fi and it still works.
