fwip compresses to lossless FLAC in your browser — identical audio, smaller file.

Compress audio without uploading it.

WAV files are large and uncompressed. FLAC gives you identical audio quality at 40-60% smaller file size. fwip converts entirely in your browser — no upload, no server, no account.

fwip works differently. The processing engine runs entirely in your browser. Your WAV is read from your device, processed on your CPU, and the result is saved back to your device. No server is involved. We literally cannot see your file.

No server processing

Everything runs on your device using WebAssembly. Your file never touches a network.

Frequently asked.

How do I convert WAV to FLAC?

No. Conversion runs entirely in your browser using WebAssembly. Your audio file never leaves your device.
