Why convert WAV to FLAC?
FLAC stores exactly the same sound as WAV in about half the space and keeps song details properly. Converting WAV to FLAC is the best way to archive recordings and CD rips without losing anything.
When to keep the WAV
Keep WAV only for software that cannot open FLAC; the FLAC holds exactly the same sound in much less space.
Tips for the best result
- FLAC is lossless: the sound is identical to the WAV.
- Files are typically 40 to 60 percent smaller.
- Most music players, phones and streaming apps play FLAC.
Common problems and fixes
- The FLAC is not much smaller.
- Noisy or very loud recordings compress less. That is normal for lossless audio.
- An app will not open FLAC.
- Some older apps and Apple Music on older systems do not support FLAC. Use WAV or ALAC there.

Frequently asked questions
Does WAV to FLAC lose quality?
No. FLAC is lossless; decoding it gives back exactly the same audio.

How do I convert WAV to FLAC?
Click Select File or drop your WAV file onto the upload box. The converted FLAC appears in the list below with a download button. You can add many files at once and download them together as a ZIP.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
