Good to know

WebP preserves the PNG alpha channel. Flat graphics compress best with lossless WebP, while photographic ones suit lossy WebP. For crisp icons, keep quality high to avoid edge fringing.

Yes. WebP supports an alpha channel and preserves transparent areas.

How much smaller than PNG?

It varies, but usually noticeably smaller — even lossless WebP often beats PNG.
