Skipping the intermediate formats, a BMP converts straight to WebP with the mode picked by inspection: flat-colour graphics compress losslessly, photographic content takes quality 82 lossy, and either way the result is dramatically smaller than the bitmap and ready for modern use. It is the one-step version of the cleanup people usually do in two. The decision is overridable under More options, and the whole process runs in your browser.

Questions

How does it decide lossless versus lossy?

It samples the image's colour distribution: few distinct colours reads as a graphic, many as a photo. The default is right nearly always and overridable regardless.

Why WebP rather than PNG or JPG?

It covers both jobs in one format with better compression than either. PNG or JPG remain right when a destination demands them specifically.

Where does this run?

Locally, in the browser.
