FAQ

Why is the output always MP3?

MP3 at a lower bitrate is what actually shrinks the file — WAV can't be compressed this way since it's uncompressed by design.

What bitrate should I pick?

96 kbps is a solid balance for speech and podcasts. For music, 128–192 kbps keeps more detail at a larger size.

Does this work on Mac, Windows, or my phone?

Yes — it runs in any modern browser on Mac, Windows, Chromebook, iPhone, or Android. No app or software to install.
