FAQ
Is this WAV to FLAC converter free, with no upload?
Yes. Conversion happens locally in your browser via FFmpeg WebAssembly — your audio never uploads. No signup, no watermark, no length cap (browser memory permitting).
Will converting WAV to FLAC lose quality?
FLAC is lossless, so converting from WAV preserves every sample. File size will be larger than lossy formats, but quality is identical to the source.
What sample rate and bitrate are used?
Defaults: 44.1 kHz / 192 kbps for MP3, 48 kHz / 128 kbps for AAC/Opus, 48 kHz / 16-bit for WAV/FLAC. Open the Audio Converter tool directly for full control.
Can I convert long files (over 1 hour)?
Yes, as long as your browser tab has enough memory (~2 GB headroom). Long files take longer because conversion is single-threaded WebAssembly on your CPU.
