About the WAV to FLAC
WAV to FLAC converts WAV audio into FLAC, right in your browser. WAV is uncompressed and completely lossless: studio-perfect quality but large files, the standard for editing and mastering. FLAC is lossless but compressed, giving you the full original quality at roughly half the size of WAV — the favourite of audiophiles.
Converting WAV to FLAC gives you a compact, lossless copy for archiving or high-quality listening. Both formats are lossless, so the audio is preserved bit-for-bit — only the file size and container change. Everything runs on your device with a WebAssembly build of ffmpeg, so your file is never uploaded — it is private, free and has no watermark. The audio engine is downloaded once (shared with the other audio and video tools) and then cached, so repeat conversions start quickly.
Frequently asked questions
Is my WAV file uploaded?
No. The conversion runs entirely in your browser with ffmpeg (WebAssembly). Your file never leaves your device.
Will I lose quality converting WAV to FLAC?
Both formats are lossless, so the audio is preserved bit-for-bit — only the file size and container change.
What bitrate should I choose?
For FLAC, 192 kbps is a good balance and 320 kbps is near-transparent. Lossless targets (WAV, FLAC, AIFF) ignore bitrate and keep full quality.
Can I convert more than one file?
Convert them one after another — each stays private on your own device, with nothing uploaded.
