Quick answer: To convert WAV to FLAC, add the WAV file to the iHateFiles WAV to FLAC converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. A lossless target, so nothing is thrown away in this step.
Should you convert WAV to FLAC?
A safe conversion: WAV and FLAC are both lossless, so the sound is identical and only the file changes.
Every sample survives
WAV and FLAC are both lossless, so the FLAC decodes to exactly the same samples as the WAV. Only the packaging changes: about 10 MB per minute as WAV, 5 to 7 MB as FLAC.
Where the FLAC will play
FLAC plays on VLC, Android, Windows 10 and later, and recent Macs.

What usually goes wrong
About the WAV. Converting an MP3 to WAV makes the file ten times larger without recovering anything. The detail the MP3 discarded is gone.
About the FLAC. Converting an MP3 to FLAC produces a large file that sounds exactly like the MP3. Lossless compression preserves what it is given, including the damage.
How to convert WAV to FLAC
- Add your WAV file. It is read from your disk and stays there.
- Check the settings. The output format is already set to FLAC.
- Press convert and the FLAC file is saved back to your device.
Questions
How do I convert WAV to FLAC?
Open this page, add your WAV file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this WAV to FLAC converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to FLAC lose quality?
FLAC is lossless, so this step throws nothing away. If the original was already a lossy format, the damage it did cannot be undone, but nothing further is lost.
Can I convert several WAV files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
