Is MP3 lower quality than WAV?

MP3 is a lossy format. At higher bitrates (e.g., 192 kbps), most listeners won’t notice a difference for typical use cases.

Do my files get uploaded?

No. All conversions happen locally in your browser using WebAssembly. Your files never leave your device.

What bitrate should I choose for speech?

96 kbps mono is a great balance for spoken word. If you include music, try 128 kbps stereo.
