Convert FLAC to WAV — Without Uploading Anything
Change FLAC into WAV for a different editing or storage workflow. Both formats support lossless audio. Keep the source rate, channels and bit depth when you want to preserve the decoded signal. Conversion runs locally in your browser.
Many converters ask you to send a recording to their server before they can do any work. Crikk reads your local file and runs the audio engine on your device. You skip the upload, and the sound stays with you. You can make another copy with different settings whenever you need one.
How to Convert FLAC to WAV
- Step 1
Add your FLAC files
Drop your files on the page or use Choose Files. You can add several recordings at once. A FLAC page accepts other supported formats too; each row shows what was actually detected.
- Step 2
Check the output format
WAV starts selected. Choose another format if your plans change, then open Advanced for bitrate, sample rate or channel settings. Leave the defaults to preserve source settings where possible.
- Step 3
Convert and download
Click Convert. Files finish one at a time so several encoders do not compete for memory. A single result downloads automatically. For a batch, download individual files or save the completed results together as a ZIP.
FLAC vs WAV: What's the Difference?
| Feature | FLAC | WAV |
|---|---|---|
| Full name | Free Lossless Audio Codec | Waveform Audio File Format |
| Type | Lossless | Lossless |
| Sound quality | Perfect, CD-quality or better | Perfect, uncompressed sound |
| File size | Medium — about 5–6 MB per minute (half of WAV) | Large — about 10 MB per minute |
| Plays on | Most players and phones; Apple Music doesn't import it | Plays on almost everything, but files are big |
| Best for | storing music in full quality, audiophile listening, backups that take less space than WAV | audio editing, music production and DAWs, voiceover delivery |
Will Converting FLAC to WAV Affect Quality?
Both FLAC and WAV can keep full audio detail. To preserve it, keep the sample rate and channels and avoid lowering bit depth. A deliberate change to those settings changes the signal even when the target format is lossless. Your source remains available for another export.
Will My File Get Bigger or Smaller?
WAV is typically about 2 times bigger than FLAC. Lossless compression reduces repeated data without throwing away sound. The actual saving depends on the recording: silence, speech and dense music do not all compress the same way.
As a rough guide, a 5 MB FLAC could become about 9 MB as WAV. Duration, channels, sample rate and bitrate all affect the result, so this is an estimate.
When to Use WAV
- audio editing. Open your audio in an editor without another lossy conversion.
- music production and DAWs. Bring the file into a digital audio workstation.
- voiceover delivery. Deliver a recording in a widely accepted editing format.
- mastering. Keep a full-size working file for the next stage.
- archiving recordings. Save a recording without discarding more audio detail.
Before choosing WAV, check what the receiving app or player accepts. Plays on almost everything, but files are big. Windows Media Player, Apple Music, QuickTime, VLC, Audacity, and any audio editor are common ways to open this format. Keep the original recording until you have played the result and confirmed that it fits your project.

Frequently Asked Questions
Is FLAC to WAV conversion lossless?
It can preserve the decoded signal when the output uses the same sample rate, channels and sufficient bit depth. Lowering those settings changes the audio.
Which should I keep, FLAC or WAV?
Choose the format your player or editor accepts. WAV is useful for audio editing; keep your original until you have checked the new file.
Is this FLAC to WAV converter free?
Yes. It is free to use with no sign-up, watermark or daily conversion limit.
Do you upload my FLAC file?
No. The file is read and processed by your browser on your device. The conversion tool does not send audio or file names to a server.
Does it work without internet?
The tool can cache the current page and its audio engine when service workers are available. Offline availability depends on your browser cache. Open the page online first; browser storage cleanup can remove cached files.
Can I convert several FLAC files?
Yes. Add a batch and convert it one file at a time. Each result has a download button. Multiple finished files can also be saved together in a ZIP.
Is there a file size limit?
There is no server upload limit because your files stay local. Very large files still depend on device memory, and output files are held in your browser. A computer is a better choice for long recordings.
Does it work on phones?
A browser with the required audio features can run the tool. Codec support varies by device. Unavailable output formats are disabled, and an error row explains when the selected file cannot be decoded.
Can I choose something other than WAV?
Yes. The page starts with WAV, but the output dropdown stays editable. Changing it updates this session without navigating to another page.
