PNG to WebP FAQ
Will transparency be preserved?
WebP can preserve transparency. JPEG cannot, but WebP and PNG can keep alpha channels.

Not always, but it often is for web graphics and mixed image assets. Very simple PNGs may already be tiny.
Are PNG files uploaded?
No. Conversion happens locally in your browser.
