Convert WAV to FLAC — Without Uploading Anything
Change WAV into FLAC 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 WAV to FLAC
- Step 1
Add your WAV files
Drop your files on the page or use Choose Files. You can add several recordings at once. A WAV page accepts other supported formats too; each row shows what was actually detected.
- Step 2
Check the output format
FLAC 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.
WAV vs FLAC: What's the Difference?
| Feature | WAV | FLAC |
|---|---|---|
| Full name | Waveform Audio File Format | Free Lossless Audio Codec |
| Type | Lossless | Lossless |
| Sound quality | Perfect, uncompressed sound | Perfect, CD-quality or better |
| File size | Large — about 10 MB per minute | Medium — about 5–6 MB per minute (half of WAV) |
| Plays on | Plays on almost everything, but files are big | Most players and phones; Apple Music doesn't import it |
| Best for | audio editing, music production and DAWs, voiceover delivery | storing music in full quality, audiophile listening, backups that take less space than WAV |
Will Converting WAV to FLAC Affect Quality?
Both WAV and FLAC 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?
FLAC is typically about 2 times smaller than WAV. 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 WAV could become about 3 MB as FLAC. Duration, channels, sample rate and bitrate all affect the result, so this is an estimate.
When to Use FLAC
- storing music in full quality. Keep a lossless music collection.
- audiophile listening. Store recordings without another lossy conversion.
- backups that take less space than WAV. Use compressed lossless files instead of large PCM files.
Before choosing FLAC, check what the receiving app or player accepts. Most players and phones; Apple Music doesn't import it. VLC, Foobar2000, Windows Media Player, most Android phones 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 WAV to FLAC 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, WAV or FLAC?
Choose the format your player or editor accepts. FLAC is useful for storing music in full quality; keep your original until you have checked the new file.
Is this WAV to FLAC converter free?
Yes. It is free to use with no sign-up, watermark or daily conversion limit.
Do you upload my WAV 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 WAV 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 FLAC?
Yes. The page starts with FLAC, but the output dropdown stays editable. Changing it updates this session without navigating to another page.
