🔒 Converted on your device. Your file is never uploaded.
WAV is uncompressed: about 10 MB per minute of stereo audio. MP3 at 192 kbps is about 1.4 MB per minute, so converting makes files small enough to email, upload, or store on a phone.
Big WAVs are exactly where uploading hurts most. Here the file is converted on your device, so a 600 MB recording starts converting immediately.

Frequently asked questions
Is my file uploaded to a server?
No. The converter (FFmpeg compiled to WebAssembly) runs inside your browser, so the file never leaves your device. That also means there is no upload wait, even for big videos.
Will I hear a difference?
At 320 kbps almost nobody can tell. At 192 kbps it’s fine for most music and all speech. Keep the WAV if you still need to edit or master it.
Do 24-bit or 96 kHz WAVs work?
Yes. They are converted to standard MP3 automatically.
