FAQ
Are WAV files uploaded to a server?
No. Conversion runs entirely in your browser with ffmpeg.wasm, so your audio never leaves your device.
Which MP3 quality should I choose?
192 kbps is a good balance of quality and size. Use 320 kbps for the best quality or 128 kbps for the smallest file.
Why does the first conversion take a moment?
The converter (about 30 MB) loads once on first use, then stays ready for further conversions in the same session.
