WAV to FLAC: FAQ
Is this WAV to FLAC converter free?
Yes. Converting WAV to FLAC is completely free with no watermark, no sign-up and no file limits beyond what your device can handle. Optional Pro features like 4K export and AI subtitles are available if you need them, and a single 4K export can be unlocked without a subscription.
Are my WAV files uploaded to a server?
No, never. The conversion runs entirely in your web browser using FFmpeg compiled to WebAssembly. Your WAV file never leaves your computer or phone, and we never store it, which makes it private and fast.
