Does it remove every pause inside the recording?

No. It removes only the sections outside your chosen start and end. Pauses inside the retained range remain.

How can I avoid cutting quiet speech?

Lower the sound threshold or add padding, then inspect the waveform and result. You can also enter start and end times manually.

Do I need to upload my file?

No. Your selected file is processed in your browser. No account is required, and the original file stays unchanged.
