WebP to JPG on Mac without extra software

Mac users hit the WebP wall constantly: images saved from Safari are .webp, Preview opens them fine but "Export" only does one file at a time, and Automator workflows for WebP are fiddly.

ConvertFlow handles WebP → JPG and WebP → PNG in bulk, right in Safari or Chrome. Drop the files, convert, download a ZIP. Nothing is installed and nothing is uploaded.

Transparency in the source WebP? Convert to PNG to keep the alpha channel; convert to JPG for maximum compatibility (transparent areas become white).
