Questions

Is my TIFF file uploaded anywhere?

No. Conversions run on your Mac; nothing is uploaded.

Will it overwrite my original?

No. The result is written next to the original with the same name and the new extension. If that name is taken it adds 2, 3 and so on.

Do I need to install anything besides Ferrocast?

This pair needs cwebp, which is optional and not bundled with Ferrocast. If it is missing, Ferrocast shows the install command: brew install webp.
